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". 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 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. Claims of quantum consciousness are, however, disputed by scientists arguing that quantum effects have no effect in systems on the macro-level systems (i.e., the brain).
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 through
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 practice
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
humors, and is treated with diet, exercise, and meditative practices based on the
medical evidence there is, however, nothing in Ayurvedic medicine is known to be effective at treating disease, and some preparations may be actively harmful, although meditation may be useful in promoting general well-being. 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 introduces 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 well-being. He has attempted to integrate Ayurveda, a traditional Indian system of medicine, with quantum mechanics 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'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. For example, 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" merges two
language games in a "completely unprincipled way". He acknowledges that AIDS is caused by the
HIV virus but says that "'hearing' the virus in its vicinity, the DNA mistakes it for a friendly or compatible sound". Ayurveda uses vibrations that 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. 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 shows the correspondences are not so close as claimed. Wanjek characterized the broadcast as "an instructive example of how bad medicine is presented as exciting news" that has "a dependence on unusual or sensational science results that others in the scientific community renounce as unsound".
Alternative medicine in June 2025 Chopra has been described as "America's most prominent spokesman for Ayurveda". Physician and former
U.S. Air Force flight surgeon Harriet Hall has criticized Chopra for his promotion of Ayurveda, stating, "It can be dangerous," referring to studies showing that 64% of Ayurvedic remedies sold in India are contaminated with significant amounts of heavy metals like mercury, arsenic, and cadmium and a 2015 study of users in the United States who found elevated blood lead levels in 40% of those tested. 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". He is placed by
David Gorski among the "quacks", "cranks", and "purveyors of woo" and described as "arrogantly obstinate". In 2013,
The New York Times stated that Deepak Chopra is "the controversial New Age guru and booster of alternative medicine". He has become one of the best-known and wealthiest figures in the holistic-health movement.
The New York 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 on its list of the 20th century's heroes and icons.
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". For
Timothy Caulfield, Chopra is an example of someone using scientific language to promote treatments that are not grounded in science: "[Chopra] legitimizes these ideas that have no scientific basis at all, and makes them sound scientific. He really is a fountain of meaningless jargon." A 2008
Time magazine article by
Ptolemy Tompkins commented that Chopra was a "magnet for criticism" for most of his career, and most of it was from the medical and scientific professionals. 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 aging 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 Worldviewsa 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". 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". 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.
Misuse of scientific terminology Physicist Sadri Hassani writes that "few people have distorted and defaced quantum physics more" than Chopra. Hassani recounts how Chopra co-opts the language of quantum mechanics and uses nonsensical diagrams to advance absurd propositions about the relation between science and
Ayurvedic medicine. Reviewing
Susan Jacoby's book
The Age of American Unreason,
Wendy Kaminer sees Chopra's popular reception in the US as 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. English professor George O'Har writes that Chopra is 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. 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 said that Shukla had 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==
