One day you too may experience what I have experienced. So right away go and practise.
B.K.S. IyengarIn your discipline, if doubt comes, let it come. You do your work and let doubt carry on with its work. And let us see which gives up first!
B.K.S. IyengarTo 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
