Regular and rhythmic breathing gives health to both body and mind. Inspiration comes from above, but it comes as light. It is the work of the mind to receive it; if the mind is not ready to receive it the inspiration will come but it will not be realized. This is like the difference between the metal gong and the wooden gong: the former will resound, the latter will not resound. It is not the fault of the one who strikes the gong, it is the gong itself which does not resound. So it is with the mind which receives the inspiration and the mind which cannot conceive it. Yet to every mind inspiration comes. The only difference is that one receives it, the other rejects it.
