For many people, that's enough of an answer, but there's more if you are interested. Yoga began in India about 5,000 years ago. At that time, people wanted to be free, healthy and live a long life, so this kind of exercise was born. The early yoga was part of a religion (宗教). It was usually taught one to one—one teacher with one student. Yoga is an Indian word that means “to join together”. There are three parts of yoga altogether: exercise, breathing and meditation (沉思). In the past, people paid more attention to the spirit. The idea behind the exercise was to join the mind, body and spirit as one. Yoga can give you peace, help you feel relaxed, and have fewer worries and illnesses. 204 小题1:What is yoga?
