Yoga is for internal cleansing, not external exercising. Yoga means true self-knowledge.
Yoga is an internal practice. The rest is just a circus.
Yoga is your mind control capacity.
Yoga is 99% practice and 1% theory.
The full ashtanga system practiced with devotion leads to freedom within one's heart.
Yoga is possible for anybody who really wants it. Yoga is universal.... But don't approach yoga with a business mind looking for worldly gain.
