True knowledge is not attained by thinking. It is what you are; it is what you become.
Sri AurobindoThe higher Truth is all the time working in us but through the lower power - Aparashakti. It is when we become conscious of the play of this higher Power then only yoga begins.
Sri AurobindoThus to act under the guidance coming from above, this is one side of the sadhana, the dynamic side. The other one is the discrimination between the Purusha and the Prakriti. The Purusha will calmly observe, give sanction, choose, but will realise that all this does not belong to him - all these are outside him. This is the static side of the sadhana. These two aspects constitute the basis of Yoga.
Sri AurobindoWhat you call the psychic being is the mind of the vital. The heart is the seat of this mind. And this mind is the essence of the senses. It receives things from outside, acts upon things that are outside - knows, gives consent, takes interest in them. But this mind cannot be the Ishwara, but it is the knower, the giver of the consent.
Sri AurobindoMaterial things are not to be despised-without them there can be no manifestation in the material world.
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.
