Besides, the natural breathing capacity of the cobra is such as no other creature shows. That capacity goes as a straight line throughout its body. The current which it gets from space and which runs through it, gives it lightness and energy and radiance and power. Compared with the cobra all other creatures are awkwardly built. The skin of the cobra is so very soft and of such silky texture, and in a moment's time it can shed its skin and be new, just as if born anew. The mystics have learnt from it. They say, "We must go out of our body just as the cobra goes out of its skin; we must go out of our thoughts, ideas, feelings, just as the cobra does with its skin." They say, "We must be able to breathe as rhythmically, to control our breath as the cobra does. We must be able to repose and relax in the same way as the cobra can. And then it will be possible to attain all we desire."
