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. IyengarHealth begins with firmness in the body, deepens to emotional stability, then leads to intellectual clarity, wisdom and finally the unveiling of the soul.
B.K.S. IyengarYoga is the rule book for playing the game of Life, but in this game no one needs to lose. It is tough, and you need to train hard. It requires the willingness to think for yourself, to observe and correct, and to surmount occasional setbacks. It demands honesty, sustained application, and above all love in your heart.
