Do to your capacity. Always strive to extend your capacity. Ten minutes today, after a few days, twelve minutes. Master that, then again extend.
B.K.S. IyengarA scientist sets out to conquer nature through knowledge - external nature, external knowledge. By these means he may split the atom and achieve external power. A yogi sets out to explore his own internal nature, to penetrate the atom (atma) of being. He does not gain dominion over wide lands and restless seas, but over his own recalcitrant flesh and febrile mind.
B.K.S. IyengarFaith, courage, and intelligent and uninterrupted awareness - these qualities are to be present whether one is wide awake, half asleep, or in deep slumber. An individual who lives like this performs his daily actions with a mind free from selfishness. This is poise in action. And this poise leads to that serenity which is in the truest sense a healthy mind in a healthy body.
