Full Disclaimer HARUKA SAKAGUCHI/The New York Times News Service Forty years ago, Deepak Chopra was a stressed-out chief of staff at a hospital in Boston, drinking and smoking too much, and desperately unhappy. The endocrinologist knew he had to get his life back on track so he took up meditation, under the tutelage of world master Maharishi Yogi, who was spiritual guru to the Beatles at the time. Within months, Chopra was on a New Age path to enlightenment. Today, his name – and the Chopra brand – is practically synonymous with the US$4.5-trillion global wellness industry.
