Last night I looked for my Indian classmate Barbara . I found her sitting with her legs crossed and quietly practicing .   Needless to say , it must be Indian Yoga .   Mary , you say something about it .   Tracing back , Yoga has a very long history . It was originated before India had approved Yoga and these documents were arranged and written according to the contents passed by mouth to mouth . In other words , Yoga is passed down from ancient times , which cannot be recalled .
