At the junction where the higher triple principle of Sat-Chit-Ananda meets the cosmic manifestation principles of Matter-Life-Mind, is “where mind and Supermind meet with a veil between them.” Because of this veil, the levels of matter, life and mind treat themselves as if they are separate and distinct from the Oneness, and this is the “ignorance” that causes suffering and struggles. Rending of the veil implies that the consciousness of the levels of sat-chit-ananda now have free and active reach into the levels of mind-life-matter and thus, inform those levels with the inherent oneness, light, knowledge, bliss operative at the highest levels. When that happens “mind can recover its divine light in the all-comprehending Supermind, the soul realise its divine self in the all-possessing all-blissful Ananda, life repossess its divine power in the play of omnipotent Conscious-Force and Matter open to its divine liberty as a form of the divine Existence.”
Sri Aurobindo points out the necessity in fact of this occurrence when he makes the case for a meaningful existence: “And if there be any goal to the evolution which finds here its present crown and head in the human being, other than an aimless circling and an individual escape from the circling, if the infinite potentiality of this creature, who alone here stands between Spirit and Matter with the power to mediate between them, has any meaning other than an ultimate awakening from the delusion of life by despair and disgust of the cosmic effort and its complete rejection, then even such a luminous and puissant transfiguration and emergence of the Divine in the creature must be that high-uplifted goal and that supreme significance.”
