Keep your attention internal, not external, not worrying about what others see, but what the Self sees.
B.K.S. IyengarA lamp does not flicker in a place where no wind blows; so it is with a yogi, who controls his mind, intellect and self, being absorbed in the spirit within him.
B.K.S. IyengarYou know the known, so go a little into the unknown. The mind that is caught up in the known - extended a little beyond reason. The moment you go beyond , you move in the soul. Releasing the bondage of your mind to extend further, reach the unknown a little more. The further you go, you realize that the known is limited and the unknown is vast.
B.K.S. Iyengar
