Thus 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 AurobindoA total spiritual direction given to the whole life and the whole nature can alone lift humanity beyond itself. . . It is only the full emergence of the soul, the full descent of the native light and power of the Spirit and the consequent replacement or transformation and uplifting of our insufficient mental and vital nature by a spiritual and supramental Supernature that can effect this evolutionary miracle.
