Death 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.
B.K.S. IyengarAny action done with beauty and purity, and in complete harmony of body, mind and soul, is Art.
B.K.S. IyengarFirst yoga deals with health, strength and conquest of the body. Next, it lifts the veil of difference between the body and the mind. Lastly, it leads the Sadhaka to peace and unalloyed purity.
B.K.S. IyengarThe challenge of yoga is to go beyond our limits - within reason. We continually expand the frame of the mind by using the canvas of the body. It is as if you were to stretch a canvas more and create a larger surface for a painting. But we must respect the present form of our body. If you pull too much at once, we will rip the canvas. If the practice of today damages the practice of tomorrow, it is not correct practice.
