I think many of my students have followed the advice I gave years ago, to give more than you take.
B.K.S. IyengarSometimes our body is willing, but our mind is weak. Sometimes our mind is willing, but our body is weak. Do not be afraid. Strive to extend your capacity but do not be disappointed with yourself. What does not challenge us, cannot change us.
B.K.S. IyengarThe cure to combat the three Ss- stress, strain, and speed- can be found in three Ws- the work of devoted practice, the wisdom that comes of understanding the self and the world, and worship because ultimately surrendering to what we cannot control allows the ego to relax and lose the anxiety of its own infinitesimally small self in the infinitude of the divine.
