Yoga 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.
B.K.S. IyengarDeath is unimportant to a yogi; he does not mind when he is going to die. What happens after death is immaterial to him. He is only concerned with life-with how he can use his life for the betterment of humanity. Having undergone various types of pain in his life and having acquired a certain mastery over pain, he develops compassion to help society and maintains himself in purity and holiness. The yogi has no interest beyond that.
