The word yoga means "union" in Sanskrit, the language of ancient India where yoga originated thousands of years ago (although noone really knows exactly how long ago) union occurring between the mind, body and spirit with the Supreme. Yoga is tool for personal transformation and self-realization. But while stretching plays its part, the aim of yoga is to create balance in the body through developing both strength and flexibility; help us become aware of our thought processes, and having calmed our mind - become more aware of our being.

That is another reason for people to tend to stick with their yoga practice for years (often becomes a lifetime practice). Those who have tried various ways to stay fit but lack motivation also tend to stick with their practice as by the end of the class, they feel wonderfully cleansed, purified, and calm, unlike some exercise programs which leave a person exhausted.
