"We speak of the evolution of Life in Matter, the evolution of Mind in Matter; but evolution is a word which merely states the phenomenon without explaining it. For there seems to be no reason why Life should evolve out of material elements or Mind out of living form, unless we accept the Vedantic solution that Life is already involved in Matter and Mind in Life because in essence Matter is a form of veiled Life, Life a form of veiled Consciousness. And then there seems to be little objection to a farther step in the series and the admission that mental consciousness may itself be only a form and a veil of higher states which are beyond Mind. In that case, the unconquerable impulse of man towards God, Light, Bliss, Freedom, Immortality presents itself in its right place in the chain as simply the imperative impulse by which Nature is seeking to evolve beyond Mind, and appears to be as natural, true and just as the impulse towards Life which she has planted in certain forms of Matter or the impulse towards Mind which she has planted in certain forms of Life. As there, so here, the impulse exists more or less obscurely in her different vessels with an ever-ascending series in the power of its will-to-be; as there, so here, it is gradually evolving and bound fully to evolve the necessary organs and faculties."The Life Divine " Aurobindo p. 5
