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 AurobindoThe mind is running on all sides to think about many things, - what we call thoughts coming from outside. We must withdraw the mind from these distractions and make it abide in the self. Thus guarding the peace within we shall have to do the work without.
Sri Aurobindo
