In recent years, yoga(瑜珈) has become popular with people for its health. Because of the focus on the physical sides of yoga, like postures and breathing, few people realize that they are taking part in an ancient practice, developing from Indian religion.

Yoga originated in India in the sixth century B. C, when people were trying to answer questions about the nature of the self and the soul. It started as a practice only done by ascetics (僧人). So it was not something that the ordinary people did.

Yoga is not only a physical practice but also a mental practice, designed to reduce the focus on the external (外部), said Whitney Sanford, professor of religious studies. Most people pay much attention to daily existence and as a result, they lead busy lives, while yoga provides people with a technique to cut off their devotion to the external.

Samantha Tam said that practicing yoga improved her flexibility and treated her injuries. “Every time after practicing yoga, I always felt really relaxed and was in a good mood,” she said.

Yoga was probably introduced on a popular level in America in the 1960s and 1970s,when Western people began to show curiosity about other religions. Now most people pursue yoga to relieve stress, and fair numbers of people are simply curious.
