[paragraph continues] This law applies to the self, not less than to the animal or the plant. Indeed, it applies first and foremost to the self, and applies to the living things that surround us because, and just so far as, they too are manifestations of the one self-evolving life. There is, however, a vital difference between the growth of the soul and the growth of any animal or plant. "The lilies of the field . . . toil not, neither do they spin: and yet . . . Solomon in all his glory was not arrayed like one of these." But if the soul is to be arrayed in glory it must both toil and spin. "Which of you," asks Christ, "by taking thought can add one cubit unto his stature?" Buddha's teaching bases itself on the assumption that by taking thought we can add to our spiritual stature, that the soul can make itself grow. Buddha would, I think, if we could question him, pass on from can to must. He would say that, when a certain stage in our development has been reached, the soul can make no further growth except what it wills to make, that it is only by the action of the will--itself one of Nature's master "streams of tendency"--that the expansive forces of Nature which are at work in the soul can be co-ordinated and made effective. He would say that the power of the soul to make itself grow is the very fruit of the whole previous process of its growth; that its presence is the proof that the process has (thus far) been successfully accomplished; that if it be wanting, the preliminary process of growth has not been carried far enough; that if, having been won, it has become atrophied through disuse, the growth of the soul has been
arrested and the counter-process of degeneration has begun.
