Yoga is a physical, mental and spiritual practice or discipline originated in India. But B. K. S. Iyengar (艾扬格) is believed to be the person who helped make yoga popular in the West. Iyengar was born into a poor family. His childhood was plagued by malaria, influenza and tuberculosis. Doctors predicted he would not live past 20. After being introduced to yoga at the age of 16, it took the young man six years to fully regain his health. In 1952 the violinist Yehudi Menuhin (耶胡迪•梅纽因) met Iyengar in India and then brought him to London. Iyengar taught yoga there, and showed people that yoga is for everyone and that, for modern people who suffer from physical pains and mental stress, yoga is the way to help integrate the mental and the physical plane, bringing about a sense of inner and outer balance.
