The Action of the Super-mind :

The Supermind represents a plane of consciousness between the Mind plane and the higher plane of Sat-Chit-Ananda. Mind divides, fragments and analyzes everything into separate parts and actions in Time. Sat-Chit-Ananda incorporates the consciousness of Oneness, infinity, universality and timelessness. It is the role of the Supermind to translate the unity into the multiplicity and to synthesize the fragmented view of the mind into a comprehensive whole. It acts both in the descent of consciousness from Oneness to Multiplicity as well as in the ascent back from Multiplicity to Oneness. In order to accomplish these things, it has to have various characteristics, which are described at some length by Sri Aurobindo : -

“It reveals the Truth behind the scattered and ill-combined suggestions of our mentality and makes each to fall into its place in the unity of the Truth behind; thus it can transform the half-light of our minds into a certain totality of light. It reveals the Will behind all the devious and imperfectly regulated striving of our mental will and emotional wishes and vital effort and makes each to fall into its place in the unity of the luminous Will behind; thus it can transform the half-obscure struggle of our life and mind into a certain totality of ordered force. It reveals the delight for which each of our sensations and emotions is groping and from which they fall back in movements of partially grasped satisfaction or of dissatisfaction, pain, grief or indifference, and makes each take its place in the unity of the universal delight behind; thus it can transform the conflict of our dualised emotions and sensations into a certain totality of serene, yet profound and powerful love and delight. Moreover, revealing the universal action, it shows the truth of being out of which each of its movements arises and to which each progresses, the force of effectuation which each carries with it and the delight of being for which and from which is born, and it relates all to the universal being, consciousness, force and delight of Sachchidananda. Thus it harmonises for us all the oppositions, divisions, contrarieties of existence and shows us in them the One and the Infinite. Uplifted into this supramental light, pain and pleasure and indifference begin to be converted into joy of the one self-existent Delight, strength and weakness, success and failure into powers of the one self-effective Force and Will, truth and error, knowledge and ignorance into light of the one infinite self-awareness and universal knowledge, increase of being and diminution of being, limitation and the overcoming of limitation into waves of the one self-realising conscious existence. All our life as well as all our essential being is transformed into the possession of Sachchidananda.”
