Purity is when there is no anxiety, no worry, no thinking.

If you open the armpits, the brain becomes light. You cannot brood or become depressed.

The yogi cannot be afraid to die, because he has brought life to every cell of his body. We are afraid to die, because we are afraid we have not lived. The yogi has lived.

He who has learnt to control his tongue has attained self-control in a great measure. When such a person speaks he will be heard with respect and attention. His words will be remembered, for they will be good and true. When one who is established in truth prays with a pure heart, then things he really needs come to him when they are really needed: he does not have to run after them. The man firmly established in truth gets the fruit of his actions without apparently doing anything. God, the source of all truth, supplies his needs and looks after his welfare.

Many ask me whether pranayama ... postpones old age. Why worry about it? Death is certain. Let it come when it comes. Just keep working. The soul has no age. It doesn't die. Only the body decays. And yet, we must never forget the body, since it is the garden we must cherish and cultivate.

Nothing is achieved by a mind that doubts

Nothing can be forced, receptivity is everything.
