The body repeats constantly and with a poignant sincerity: “What am I to demand anything whatsoever from anyone at all? Left to myself I am nothing, I know nothing, I can do nothing. Unless the truth penetrates into me and directs me, I am incapable of taking even the minutest decision and of knowing what is the best thing to do and to live even in the most insignificant circumstance. Shall I ever be capable of being transformed to the point of becoming What I ought to be and of manifesting What wants to manifest upon earth?” But why does this answer always come from the depths, from You, Lord, with an indisputable certitude: “If you cannot do it, no other body upon earth can do it.” There is but one conclusion: I shall persist in my effort, without giving in, I shall persist until death or until victory.

And your body, if you draw from it all the possibilities it holds, if you educate it by the normal, well-known, scientific methods, if you make this instrument into something as perfect as possible, then, when the supramental truth manifests in that body, it will become immediately—without centuries of preparation—a marvellous instrument for the expression of the Spirit.
That is why Sri Aurobindo used to repeat and has always said: You must work from both ends, not let go of one for the other. And certainly, if you want to have a divine consciousness, you must not give up spiritual aspiration; but if you want to become an integral divine being on earth, take good care not to let go of the other end, and make your body the best possible instrument.
