Introduction

Supermind in Sri Aurobindo's philosophy refers to the infinite unitary truth-consciousness or truth-idea simultaneously transcendent and immanent to planes of matter, life, and mind. Supermind is the dynamic form of sachchidananda (being-consciousness-bliss), and the necessary conduit, mediator or linkage between satchitananda and the manifest Creation. (Life Divine Book I, ch.14-16)

The objective and final stage of integral yoga is to actualise the Supermind within one's being, this would constitute a divinisation of matter itself or a realisation of its inherent primordial propensity, and usher in a completely new, 'divine' way of existing. (Life Divine Book II, ch.26-28)

Quotes:

"The term above is the unitarian or indivisible consciousness of pure Sachchidananda in which there are no separating distinctions; the term below is the analytic or dividing consciousness of Mind which can only know by separation and distinction and has at the most a vague and secondary apprehension of unity and infinity,-for, though it can synthetise its divisions, it cannot arrive at a true totality. Between them is this comprehensive and creative consciousness, by its power of pervading and intimately comprehending knowledge the child of that self-awareness by identity which is the poise of the Brahman and by its power of projecting, confronting, apprehending knowledge parent of that awareness by distinction which is the process of the Mind."

"Above, the formula of the One eternally stable and immutable; below, the formula of the Many which, eternally mutable, seeks but hardly finds in the flux of things a firm and immutable standing-point; between, the seat of all trinities, of all that is biune, of all that becomes Many-in-One and yet remains One-in-Many because it was originally One that is always potentially Many. This intermediary term is therefore the beginning and end of all creation and arrangement, the Alpha and the Omega, the starting-point of all differentiation, the instrument of all unification, originative, executive and consummative of all realised or realisable harmonies. It has the knowledge of the One, but is able to draw out of the One its hidden multitudes; it manifests the Many, but does not lose itself in their differentiations. And shall we not say that its very existence points back to Something beyond our supreme perception of the ineffable Unity, -- Something ineffable and mentally inconceivable not because of its unity and indivisibility, but because of its freedom from even these formulations of our mind, -- Something beyond both unity and multiplicity? That would be the utter Absolute and Real which yet justifies to us both our knowledge of God and our knowledge of the world."

"the supermind, the Truth-consciousness, the Real-Idea which knows itself and all that it becomes. "

"Consciousness and Force are the twin essential aspects of the pure Power of existence; Knowledge and Will must therefore be the form which that Power takes in creating a world of relations in the extension of Time and Space. This Knowledge and this Will must be one, infinite, all-embracing, all-possessing, all-forming, holding eternally in itself that which it casts into movement and form. The supermind then is Being moving out into a determinative self-knowledge which perceives certain truths of itself and wills to realise them in a temporal and spatial extension of its own timeless and spaceless existence. Whatever is in its own being, takes form as self-knowledge, as Truth-Consciousness, as Real-Idea, and, that self-knowledge being also self-force, fulfils or realises itself inevitably in Time and Space."
