B.K.S. IyengarWe are creatures that are designed for continual challenge. We must grow or we begin to die....So just standing still isn't really an option. We have to move on. If not, disturbances will come.
B.K.S. IyengarThrough surrender the aspirant's ego is effaced, and . . . grace . . . pours down upon him like a torrential rain.
