A quiet mind does not mean that there will be no thoughts or mental movements at all, but that these will be on the surface, and you will feel your true being within, separate from them, observing but not carried away
Sri AurobindoBut what after all, behind appearances, is this seeming mystery? We can see that it is the Consciousness which had lost itself returning again to itself, emerging out of its giant self-forgetfulness, slowly, painfully, as a Life that is would be sentient, half-sentient, dimly sentient, wholly sentient and finally struggles to be more than sentient, to be again divinely selfconscious, free, infinite, immortal.
Sri AurobindoThe yogin becomes aware in part of the action of the supramental power organizing the lower vehicle (ฤdhฤra). A part of it remains behind the veil and prepares itself.
Sri AurobindoFor the powers of our mind, life, and body are bound to their own limitations, and however high they may rise or however widely expand, they cannot rise beyond them. But still, mental man can open to what is beyond him and call down a Supramental Light, Truth, and Power to work in him and do what the mind cannot do. If mind cannot by effort become what is beyond mind, Supermind can descend and transform mind into its own substance.
Sri Aurobindo
