Spirit manifesting in Nature

"Aurobindo saw humanity at a crossroads in its evolution: [he wrote] "If a spiritual unfolding on earth is the hidden truth of our birth into Matter, if it is fundamentally an evolution of consciousness that has been taking place in Nature, then man as he is cannot be the last term of that evolution: he is too imperfect an expression of spirit, mind itself is a too limited form and instrumentation; mind is only a middle term of consciousness, the mental term of consciousness, the mental being can only be a transitional being. If, then, man is incapable of exceeding mentality, he must be surpassed and supermind and superman must manifest and take the lead of creation. But if his mind is capable of opening to what exceeds it, then there is no reason why man himself should not arrive at supermind and supermanhood or at least lend his mentality, life and body to an evolution of that greater term of the Spirit manifesting in Nature."
