In 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. IyengarI am old, and death inevitably approaches. But both birth and death are beyond the will of a human being. They are not my domain. I do not think about it. Yoga has taught me to think of only working to live a useful life...I will never stop learning, and it have tried to share some lessons with you. I do pray that my ending will be your beginning. The great rewards and the countless blessings of a life spent following the Inward Journey await you.
