To do is hard, but to teach is still harder. Do not teach only to teach. Teach to improve the pupil. To be a teacher requires tremendous, vigorous discipline on oneself. We are teachers because somebody demands it from us. But the teacher should first rub his own self, and teach afterwards
B.K.S. IyengarThe 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.
B.K.S. Iyengar
