Aurobindo on Involution

Since this Consciousness is creatrix of the world, it must be not only state of knowledge, but power of knowledge, and not only a will to light and vision but a will to power and works. And since mind too is created out of it, mind must be a development by limitation out of this primal faculty and this supreme consciousness and must therefore be capable of resolving itself back into it through a reverse development by expansion.

-- Sri Aurobindo, from The Life Divine
