There is a veil between the Supermind above and the lower Prakriti below - the veil of ingrained formations. This veil may completely withdraw or be partially withdrawn. Thus even if there is some little opening, with the contact of Light from above the lower nature will get slowly changed.
Sri AurobindoOne may come armoured, Invinsible. His will immobile meets the mobile hour. The world blows cannot bend this Victor Head. Calm and sure are his steps in the growing night. The goal recedes, he hurries not his pace. He asks from no help from the inferior Gods. His eyes are fixed on the immutable aim.
Sri AurobindoIf it be true that spirit is involved in Matter and apparent Nature is secret God, then the manifestation in the divine in himself and the realization of God within and without are the highest and most legitimate aim possible to man on earth.
Sri Aurobindo
