Deepak Chopra (born October 22, 1946) is an American author, public speaker, alternative medicine advocate, and a prominent figure in the New Age movement. Through his books and videos, he has become one of the best-known and wealthiest figures in alternative medicine.
Chopra studied medicine in India before emigrating to the United States in 1970 where he completed residencies in internal medicine and endocrinology. As a licensed physician, he became chief of staff at the New England Memorial Hospital (NEMH) in 1980. He met Maharishi Mahesh Yogi in 1985 and became involved with the Transcendental Meditation movement (TM). He resigned his position at NEMH shortly thereafter to establish the Maharishi Ayurveda Health Center. Chopra gained a following in 1993 after his interview on The Oprah Winfrey Show regarding his books. He then left the TM movement to become the executive director of Sharp HealthCare's Center for Mind-Body Medicine and in 1996 he co-founded the Chopra Center for Wellbeing.
Chopra believes that a person may attain "perfect health", a condition "that is free from disease, that never feels pain", and "that cannot age or die". Seeing the human body as being undergirded by a "quantum mechanical body" composed not of matter but of energy and information, he believes that "human aging is fluid and changeable; it can speed up, slow down, stop for a time, and even reverse itself," as determined by one's state of mind. He claims that his practices can also treat chronic disease. As of 2014, Deepak Chopra lived in a "health-centric" condominium in Manhattan.
The ideas Chopra promotes have been regularly criticized by medical and scientific professionals as pseudoscience. This criticism has been described as ranging "from dismissive [to] damning". For example, Robert Carroll states Chopra attempts to integrate Ayurveda with quantum mechanics to justify his teachings. Chopra argues that what he calls "quantum healing" cures any manner of ailments, including cancer, through effects that he claims are literally based on the same principles as quantum mechanics. This has led physicists to object to his use of the term quantum in reference to medical conditions and the human body. His treatments benefit from the placebo response, and some argue that his claims for the effectiveness of alternative medicine can lure sick people away from medical treatments. He is placed by David Gorski among the "quacks", "cranks" and "purveyors of woo", and described as "arrogantly obstinate". Richard Dawkins publicly exposed Chopra, accusing him of using "quantum jargon as plausible-sounding hocus pocus".

Biography
Early life and education
Chopra was born in New Delhi, India, to Krishan Lal Chopra (1919-2001) and Pushpa Chopra.
His paternal grandfather was a sergeant in the British Indian Army. His father was a prominent cardiologist, head of the department of medicine and cardiology at New Delhi's Moolchand Khairati Ram Hospital for over 25 years; he was also a lieutenant in the British army, serving as an army doctor at the front at Burma and acting as a medical adviser to Lord Mountbatten, viceroy of India. As of 2014 Chopra's younger brother, Sanjiv Chopra, is a professor of medicine at Harvard Medical School and on staff at Beth Israel Deaconess Medical Center.
Chopra completed his primary education at St. Columba's School in New Delhi and graduated from the All India Institute of Medical Sciences in 1969. He spent his first months as a doctor working in rural India, including, he writes, six months in a village where the lights went out whenever it rained. It was during his early career that he was drawn to study endocrinology, particularly neuroendocrinology, to find a biological basis for the influence of thoughts and emotions.
He married in India in 1970 before emigrating with his wife that year to the United States. The Indian government had banned its doctors from sitting the American Medical Association exam needed to practice in the USA, so Chopra had to travel to Sri Lanka to take it. After passing he arrived in the United States to take up a clinical internship at Muhlenberg Hospital in Plainfield, New Jersey, where doctors from overseas were being recruited to replace those serving in Vietnam.
Between 1971 and 1977 he completed residencies in internal medicine at the Lahey Clinic in Burlington, Massachusetts, the VA Medical Center, St Elizabeth's Medical Center and Beth Israel Deaconess Medical Center in Boston. He earned his license to practice medicine in the state of Massachusetts in 1973, becoming board certified in internal medicine, specializing in endocrinology.
East Coast years
Chopra taught at the medical schools of Tufts University, Boston University and Harvard University, and became Chief of Staff at the New England Memorial Hospital (NEMH) (later known as the Boston Regional Medical Center) in Stoneham, Massachusetts, before establishing a private practice in Boston in endocrinology.
While visiting New Delhi in 1981, he met the physician Brihaspati Dev Triguna, head of the Indian Council for Ayurvedic Medicine, whose advice prompted him to begin investigating Ayurvedic practices. Chopra was "drinking black coffee by the hour and smoking at least a pack of cigarettes a day". He took up Transcendental Meditation to help him stop; as of 2006 he continued to meditate for two hours every morning and half an hour in the evening.
Chopra's involvement with TM led to a meeting, in 1985, with the leader of the TM movement, Maharishi Mahesh Yogi, who asked him to establish an Ayurvedic health center. He left his position at the NEMH. Chopra said that one of the reasons he left was his disenchantment at having to prescribe too many drugs: "[W]hen all you do is prescribe medication, you start to feel like a legalized drug pusher. That doesn't mean that all prescriptions are useless, but it is true that 80 percent of all drugs prescribed today are of optional or marginal benefit."
He became the founding president of the American Association of Ayurvedic Medicine, one of the founders of Maharishi Ayur-Veda Products International, and medical director of the Maharishi Ayur-Veda Health Center in Lancaster, Massachusetts. The center charged between $2,850 and $3,950 a week for Ayurvedic cleansing rituals such as massages, enemas and oil baths; TM lessons cost an additional $1,000. Celebrity patients included Elizabeth Taylor. Chopra also became one of the TM movement's spokespersons. In 1989 the Maharishi awarded him the title "Dhanvantari of Heaven and Earth" (Dhanvantari is the Hindu physician to the gods). That year Chopra's Quantum Healing: Exploring the Frontiers of Mind/Body Medicine was published, followed by Perfect Health: The Complete Mind/Body Guide (1990).
West Coast years
In June 1993 he moved to California as executive director of Sharp HealthCare's Institute for Human Potential and Mind/Body Medicine, and head of their Center for Mind/Body Medicine, a clinic in an exclusive resort in Del Mar, California that charged $4,000 a week and included Michael Jackson's family among its clients. Chopra and Jackson first met in 1988 and remained friends for 20 years. When Jackson died in 2009 after being administered prescription drugs, Chopra said he hoped it would be a call to action against the "cult of drug-pushing doctors, with their co-dependent relationships with addicted celebrities".
Chopra left the Transcendental Meditation movement around the time he moved to California in January 1993. By his own account, the Maharishi had accused him of competing for the Maharishi's position as guru, although Chopra rejects identification as a "guru". According to Robert Todd Carroll, Chopra left the TM organization when it "became too stressful" and was a "hindrance to his success". Cynthia Ann Humes writes that the Maharishi was concerned, and not only with regard to Chopra, that rival systems were being taught at lower prices. Chopra, for his part, was worried that his close association with the TM movement might prevent Ayurvedic medicine from being accepted as legitimate, particularly after the problems with the JAMA article. He also stated that he had become uncomfortable with what seemed like a "cultish atmosphere around Maharishi".
In 1995 Chopra was not licensed to practice medicine in California where he had a clinic; however, he did not see patients at this clinic "as a doctor" during this time. In 2004 he received his California medical licence, and as of 2014 is affiliated with Scripps Memorial Hospital in La Jolla, California. Chopra is the owner and supervisor of the Mind-Body Medical Group within the Chopra Center, which in addition to standard medical treatment offers personalized advice about nutrition, sleep-wake cycles and stress management, based on mainstream medicine and Ayurveda. He is a fellow of the American College of Physicians and member of the American Association of Clinical Endocrinologists.
The couple had two adult children and three grandchildren as of 2013. As of 2014, Deepak Chopra lived in a "health-centric" condominium in Manhattan.
Alternative medicine business
Chopra's Ageless Body, Timeless Mind: The Quantum Alternative to Growing Old was published in 1993. The book and his friendship with Michael Jackson gained him an interview on July 12 that year on Oprah, which made him a household name. Paul Offit writes that within 24 hours Chopra had sold 137,000 copies of his book and 400,000 by the end of the week. Four days after the interview, the Maharishi National Council of the Age of Enlightenment wrote to TM centers in the United States, instructing them not to promote Chopra, and his name and books were removed from the movement's literature and health centers. Neuroscientist Tony Nader became the movement's new "Dhanvantari of Heaven and Earth".
Sharp HealthCare changed ownership in 1996 and Chopra left to set up the Chopra Center for Wellbeing with neurologist David Simon, now located at the Omni La Costa Resort and Spa in Carlsbad, California. In his 2013 book Do You Believe in Magic?, Paul Offit writes that Chopra's business grosses approximately $20 million annually, and is built on the sale of various alternative medicine products such as herbal supplements, massage oils, books, videos and courses. A year's worth of products for "anti-ageing" can cost up to $10,000, Offit wrote. Chopra himself is estimated to be worth over $80 million as of 2014. As of 2005, according to Srinivas Aravamudan, he was able to charge $25,000 to $30,000 per lecture five or six times a month. Medical anthropologist Hans Baer said Chopra was an example of a successful entrepreneur, but that he focused too much on serving the upper-class through an alternative to medical hegemony, rather than a truly holistic approach to health.
Teaching and other roles
Chopra serves as an adjunct professor in the marketing division at Columbia Business School. He serves as adjunct professor of executive programs at the Kellogg School of Management at Northwestern University. He participates annually as a lecturer at the Update in Internal Medicine event sponsored by Harvard Medical School and the Beth Israel Deaconess Medical Center. Robert Carroll writes of Chopra charging $25,000 per lecture, "giving spiritual advice while warning against the ill effects of materialism".
In 2015, Chopra partnered with businessman Paul Tudor Jones II to found JUST Capital, a non-profit which ranks companies in terms of just business practices in an effort to promote economic justice. In 2014 Chopra founded ISHAR (Integrative Studies Historical Archive and Repository). In 2012, Chopra joined the board of advisors for tech startup State.com, creating a browsable network of structured opinions. In 2009 Chopra founded the Chopra Foundation, a tax-exempt 501(c) organization that raises funds to promote and research alternative health. The Foundation sponsors annual Sages and Scientists conferences. He sits on the board of advisors of the National Ayurvedic Medical Association. Chopra founded the American Association for Ayurvedic Medicine (AAAM) and Maharishi AyurVeda Products International, though he later distanced himself from these organizations. In 2005 Chopra was appointed as a senior scientist at The Gallup Organization. Since 2004 he has been a board member of Men's Wearhouse, a men's clothing distributor. In 2006 he launched Virgin Comics with his son Gotham Chopra and entrepreneur Richard Branson. In 2016 Chopra was promoted from assistant professor to full professor at the University of California, San Diego in their Department of Family Medicine.
Ideas and reception
Chopra believes that a person may attain "perfect health", a condition "that is free from disease, that never feels pain", and "that cannot age or die". Seeing the human body as being undergirded by a "quantum mechanical body" comprised not of matter but of energy and information, he believes that "human aging is fluid and changeable; it can speed up, slow down, stop for a time, and even reverse itself," as determined by one's state of mind. He claims that his practices can also treat chronic disease.
Consciousness
Chopra speaks and writes regularly about metaphysics, including the study of consciousness and Vedanta philosophy. He is a philosophical idealist, arguing for the primacy of consciousness over matter and for teleology and intelligence in nature - that mind, or "dynamically active consciousness", is a fundamental feature of the universe.
In this view, consciousness is both subject and object. It is consciousness, he writes, that creates reality; we are not "physical machines that have somehow learned to think...[but] thoughts that have learned to create a physical machine". He argues that the evolution of species is the evolution of consciousness seeking to express itself as multiple observers; the universe experiences itself through our brains: "We are the eyes of the universe looking at itself". He has been quoted as saying "Charles Darwin was wrong. Consciousness is key to evolution and we will soon prove that." He opposes reductionist thinking in science and medicine, arguing that we can trace the physical structure of the body down to the molecular level and still have no explanation for beliefs, desires, memory and creativity. In his book Quantum Healing, Chopra stated the conclusion that quantum entanglement links everything in the Universe, and therefore it must create consciousness.
Approach to health care
Chopra argues that everything that happens in the mind and brain is physically represented elsewhere in the body, with mental states (thoughts, feelings, perceptions and memories) directly influencing physiology by means of neurotransmitters such as dopamine, oxytocin and serotonin. He has stated, "Your mind, your body and your consciousness - which is your spirit - and your social interactions, your personal relationships, your environment, how you deal with the environment, and your biology are all inextricably woven into a single process ... By influencing one, you influence everything."
Chopra and physicians at the Chopra Center practise integrative medicine, combining the medical model of conventional Western medicine with alternative therapies such as yoga, mindfulness meditation, and Ayurveda. According to Ayurveda, illness is caused by an imbalance in the patient's doshas or humours, and is treated with diet, exercise and meditative practices - based on the medical evidence there is, however, nothing in Ayurvedic medicine that is known to be effective at treating disease, and some preparations may be actively harmful, although meditation may be useful in promoting general wellbeing.
In discussing health care, Chopra has used the term "quantum healing", which he defined in Quantum Healing (1989) as the "ability of one mode of consciousness (the mind) to spontaneously correct the mistakes in another mode of consciousness (the body)". This attempted to wed the Maharishi's version of Ayurvedic medicine with concepts from physics, an example of what cultural historian Kenneth Zysk called "New Age Ayurveda". The book introduced Chopra's view that a person's thoughts and feelings give rise to all cellular processes.
Chopra coined the term quantum healing to invoke the idea of a process whereby a person's health "imbalance" is corrected by quantum mechanical means. Chopra said that quantum phenomena are responsible for health and wellbeing. He has attempted to integrate Ayurveda, a traditional Indian system of medicine, with quantum mechanics, in order to justify his teachings. According to Robert Carroll, he "charges $25,000 per lecture performance, where he spouts a few platitudes and gives spiritual advice while warning against the ill effects of materialism".
Chopra has equated spontaneous remission in cancer to a change in quantum state, corresponding to a jump to "a new level of consciousness that prohibits the existence of cancer". Physics professor Robert L. Park has written that physicists "wince" at the "New Age quackery" in Chopra's cancer theories, and characterizes them as a cruel fiction, since adopting them in place of effective treatment risks compounding the ill effects of the disease with guilt, and might rule out the prospect of getting a genuine cure.
Chopra's claims of quantum healing have attracted controversy due to what has been described as a "systematic misinterpretation" of modern physics. Chopra's connections between quantum mechanics and alternative medicine are widely regarded in the scientific community as being invalid. The main criticism revolves around the fact that macroscopic objects are too large to exhibit inherently quantum properties like interference and wave function collapse. Most literature on quantum healing is almost entirely theosophical, omitting the rigorous mathematics that makes quantum electrodynamics possible.
Physicists have objected to Chopra's use of terms from quantum physics; he was awarded the satirical Ig Nobel Prize in physics in 1998 for "his unique interpretation of quantum physics as it applies to life, liberty, and the pursuit of economic happiness". When Chopra and Jean Houston debated Sam Harris and Michael Shermer in 2010 on the question "Does God Have a Future?", Harris argued that Chopra's use of "spooky physics" merged two language games in a "completely unprincipled way". Interviewed in 2007 by Richard Dawkins, Chopra said that he used the term quantum as a metaphor when discussing healing and that it had little to do with quantum theory in physics.
Chopra wrote in 2000 that his AIDS patients were combining mainstream medicine with activities based on Ayurveda, including taking herbs, meditation and yoga. He acknowledges that AIDS is caused by the HIV virus, but says that, "'[h]earing' the virus in its vicinity, the DNA mistakes it for a friendly or compatible sound". Ayurveda uses vibrations which are said to correct this supposed sound distortion. Medical professor Lawrence Schneiderman writes that Chopra's treatment has "to put it mildly...no supporting empirical data".
In 2001, ABC News aired a show segment on the topic of distance healing and prayer. In it Chopra said that "there is a realm of reality that goes beyond the physical where in fact we can influence each other from a distance". Chopra was shown using his claimed mental powers in an attempt to relax a person in another room, whose vital signs were recorded in charts which were said to show a correspondence between Chopra's periods of concentration and the subject's periods of relaxation. After the show, a poll of its viewers found that 90% of them believed in distance healing. Health and science journalist Christopher Wanjek has criticized the experiment, saying that any correspondence evident from the charts would prove nothing, but that even so freezing the frame of the video showed the correspondences were not so close as claimed. Wanjek characterized the broadcast as "an instructive example of how bad medicine is presented as exciting news" which had "a dependence on unusual or sensational science results that others in the scientific community renounce as unsound".
Alternative medicine
Chopra has been described as "America's most prominent spokesman for Ayurveda". His treatments benefit from the placebo response. Chopra states "The placebo effect is real medicine, because it triggers the body's healing system."
Chopra has metaphorically described the AIDS virus as emitting "a sound that lures the DNA to its destruction". The condition can be treated, according to Chopra, with "Ayurveda's primordial sound". Taking issue with this view, medical professor Lawrence Schneiderman has said that ethical issues are raised when alternative medicine is not based on empirical evidence and that, "to put it mildly, Dr. Chopra proposes a treatment and prevention program for AIDS that has no supporting empirical data".
He is placed by David Gorski among the "quacks", "cranks" and "purveyors of woo", and described as "arrogantly obstinate". The New York Times in 2013 stated that Deepak Chopra is "the controversial New Age guru and booster of alternative medicine". The Time magazine stated that he is "the poet-prophet of alternative medicine." He has become one of the best-known and wealthiest figures in the holistic-health movement. The Times argued that his publishers have used his medical degree on the covers of his books as a way to promote the books and buttress their claims. In 1999 Time magazine included Chopra in its list of the 20th century's heroes and icons. The following year Mikhail Gorbachev referred to him as "one of the most lucid and inspired philosophers of our time". Cosmo Landesman wrote in 2005 that Chopra was "hardly a man now, more a lucrative new age brand - the David Beckham of personal/spiritual growth". A 2008 Time magazine article by Ptolemy Tompkins commented that for most of his career Chopra had been a "magnet for criticism", and most of it was from the medical and scientific professionals. Opinions ranged from the "dismissive" to the "outright damning". Chopra's claims for the effectiveness of alternative medicine can, some have argued, lure sick people away from medical treatments. Tompkins however considered Chopra a "beloved" individual whose basic messages centered on "love, health and happiness" had made him rich because of their popular appeal. English professor George O'Har argues that Chopra exemplifies the need of human beings for meaning and spirit in their lives, and places what he calls Chopra's "sophistries" alongside the emotivism of Oprah Winfrey. Paul Kurtz writes that Chopra's "regnant spirituality" is reinforced by postmodern criticism of the notion of objectivity in science, while Wendy Kaminer equates Chopra's views with irrational belief systems such as New Thought, Christian Science, and Scientology.
Aging
Chopra believes that "ageing is simply learned behaviour" that can be slowed or prevented. Chopra has said that he expects "to live way beyond 100". He states that "by consciously using our awareness, we can influence the way we age biologically...You can tell your body not to age." Conversely, Chopra also says that ageing can be accelerated, for example by a person engaging in "cynical mistrust".
Robert Todd Carroll has characterized Chopra's promotion of lengthened life as a selling of "hope" that seems to be "a false hope based on an unscientific imagination steeped in mysticism and cheerily dispensed gibberish".
Spirituality and religion
Chopra has likened the universe to a "reality sandwich" which has three layers: the "material" world, a "quantum" zone of matter and energy, and a "virtual" zone outside of time and space, which is the domain of God, and from which God can direct the other layers. Chopra has written that human beings' brains are "hardwired to know God" and that the functions of the human nervous system mirror divine experience. Chopra has written that his thinking has been inspired by Jiddu Krishnamurti, a 20th-century speaker and writer on philosophical and spiritual subjects.
In 2012, reviewing War of the Worldviews - a book co-authored by Chopra and Leonard Mlodinow - physics professor Mark Alford says that the work is set out as a debate between the two authors, "[covering] all the big questions: cosmology, life and evolution, the mind and brain, and God". Alford considers the two sides of the debate a false opposition, and says that "the counterpoint to Chopra's speculations is not science, with its complicated structure of facts, theories, and hypotheses," but rather Occam's razor.
In August 2005, Chopra wrote a series of articles on the creation-evolution controversy and Intelligent design, which were criticized by science writer Michael Shermer, founder of The Skeptics Society. In 2010, Shermer said that Chopra is "the very definition of what we mean by pseudoscience".
Position on skepticism
Paul Kurtz, an American skeptic and secular humanist, has written that the popularity of Chopra's views is associated with increasing anti-scientific attitudes in society, and such popularity represents an assault on the objectivity of science itself by seeking new, alternative forms of validation for ideas. Kurtz says that medical claims must always be submitted to open-minded but proper scrutiny, and that skepticism "has its work cut out for it".
In 2013, Chopra published an article on what he saw as "skepticism" at work in Wikipedia, arguing that a "stubborn band of militant skeptics" were editing articles to prevent what he believes would be a fair representation of the views of such figures as Rupert Sheldrake, an author, lecturer, and researcher in parapsychology. The result, Chopra argued, was that the encyclopedia's readers were denied the opportunity to read of attempts to "expand science beyond its conventional boundaries". The biologist Jerry Coyne responded, saying that it was instead Chopra who was losing out as his views were being "exposed as a lot of scientifically-sounding psychobabble".
More broadly, Chopra has attacked skepticism as a whole, writing in The Huffington Post that "No skeptic, to my knowledge, ever made a major scientific discovery or advanced the welfare of others." Astronomer Phil Plait said this statement trembled "on the very edge of being a blatant and gross lie", listing Carl Sagan, Richard Feynman, Stephen Jay Gould, and Edward Jenner among the "thousands of scientists [who] are skeptics", who he said were counterexamples to Chopra's statement.
Use of scientific terminology
Reviewing Susan Jacoby's book, The Age of American Unreason, Wendy Kaminer sees Chopra's popular reception in the USA as being symptomatic of many Americans' historical inability (as Jacoby puts it) "to distinguish between real scientists and those who peddled theories in the guise of science". Chopra's "nonsensical references to quantum physics" are placed in a lineage of American religious pseudoscience, extending back through Scientology to Christian Science. Physics professor Chad Orzel has written that "to a physicist, Chopra's babble about 'energy fields' and 'congealing quantum soup' presents as utter gibberish", but that Chopra makes enough references to technical terminology to convince non-scientists that he understands physics. English professor George O'Har writes that Chopra is as an exemplification of the fact that human beings need "magic" in their lives, and places "the sophistries of Chopra" alongside the emotivism of Oprah Winfrey, the special effects and logic of Star Trek, and the magic of Harry Potter.
Chopra has been criticized for his frequent references to the relationship of quantum mechanics to healing processes, a connection that has drawn skepticism from physicists who say it can be considered as contributing to the general confusion in the popular press regarding quantum measurement, decoherence and the Heisenberg uncertainty principle. In 1998, Chopra was awarded the satirical Ig Nobel Prize in physics for "his unique interpretation of quantum physics as it applies to life, liberty, and the pursuit of economic happiness". When interviewed by ethologist and evolutionary biologist Richard Dawkins in the Channel 4 (UK) documentary The Enemies of Reason, Chopra said that he used the term "quantum physics" as "a metaphor" and that it had little to do with quantum theory in physics. In March 2010, Chopra and Jean Houston debated Sam Harris and Michael Shermer at the California Institute of Technology on the question "Does God Have a Future?" Shermer and Harris criticized Chopra's use of scientific terminology to expound unrelated spiritual concepts.
A 2015 paper examining "the reception and detection of pseudo-profound bullshit" used Chopra's Twitter feed as the canonical example, and compared this with fake Chopra quotes generated by a spoof website.
Yoga
In April 2010 Aseem Shukla, co-founder of the Hindu American Foundation, criticized Chopra for suggesting that yoga did not have its origins in Hinduism but in an older Indian spiritual tradition. Chopra later said that yoga was rooted in "consciousness alone" expounded by Vedic rishis long before historic Hinduism ever arose. He accused Shukla of having a "fundamentalist agenda". Shukla responded by saying Chopra was an exponent of the art of "How to Deconstruct, Repackage and Sell Hindu Philosophy Without Calling it Hindu!", and he said Chopra's mentioning of fundamentalism was an attempt to divert the debate.
Legal actions
In May 1991, the Journal of the American Medical Association (JAMA) published an article by Chopra and two others on Ayurvedic medicine and TM. JAMA subsequently published an erratum stating that the lead author, Hari M. Sharma, had undisclosed financial interests, followed by an article by JAMA associate editor Andrew A. Skolnick which was highly critical of Chopra and the other authors for failing to disclose their financial connections to the article subject. Several experts on meditation and traditional Indian medicine criticized JAMA for accepting the "shoddy science" of the original article. Chopra and two TM groups sued Skolnick and JAMA for defamation, asking for $194 million in damages, but the case was dismissed in March 1993.
Chopra was sued for copyright infringement by Robert Sapolsky, for using a chart displaying information on the endocrinology of stress without proper attribution, after the publication of Chopra's book Ageless Body, Timeless Mind. "An out-of-court settlement" resulted in Chopra correctly attributing material that was researched by Sapolsky.
Select bibliography
As of 2015, Chopra has written 80 books, 21 of them New York Times bestsellers, which have been translated into 43 languages. His book The Seven Spiritual Laws of Success was on The New York Times Best Seller list for 72 weeks.
