Nobody really enjoys having to pacify their feelings. It's too much like failure; it reminds you of weakness. but feelings don't want to be pacified, either. They want to be fulfilled. You fulfill your positive feelings (love, hope, optimism, appreciation, approval) by connecting with other people, expressing your best self. You fulfill your negative feelings by releasing them. Your whole system recognizes negative feelings as toxic. It's futile to bottle them up, divert them, ignore them, or try to rise above them. Either negativity is leaving or it's hanging on - it has no other alternative. As you fulfill emotions, your brain will change and form new patterns, which is the whole goal.

Reviewing Susan Jacoby's book The Age of American Unreason Kaminer (2008) sees Chopra's popular reception in America 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". He currently serves as an Adjunct Professor of Executive Programs at the Kellogg School of Management at Northwestern University. The documentary is directed by actress Namrata Singh Gujral and also features cancer survivors Olivia Newton-John Diahann Carroll Melissa Etheridge Mumtaz and Jaclyn Smith.

His books have been translated into 35 languages and sold more than 20 million copies worldwide. Chopra has taught at the medical schools of Tufts University Boston University and Harvard University. His critics accuse him of creating a false sense of hope in sick individuals which may keep them away from effective medical care.
