The material body has a practical reality that is accessible. It is here and now, and we can do something with it. However, we must not forget that the innermost part of our being is also trying to help us. It wants to come out to the surface and express itself.
The yogi cannot be afraid to die, because he has brought life to every cell of his body. We are afraid to die, because we are afraid we have not lived. The yogi has lived.
The Yogi conquers the body by the practice of asanas, making the body a fit vehicle for the spirit. The Yogi knows that it is a necessary vehicle for the spirit, for a soul without a body is like a bird deprived of its power to fly.
I also say with backbends, you have to be cautiously bold. Not carelessly bold. You have to descend to the dictation of the spine. You cannot command from the brain to do the poses. As you play with a child, guarding the child from injuries, similarly you have to play in backbends, guarding your spine.
