The Force which has to be called down from above must be pure and quiet because there are all kinds of forces - it will not do to call them all. And one must have sincerity.
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 AurobindoSafety lies in tending towards our highest and not in resting content with an inferior potentiality..... To rest in or follow after an inferior potentiality may seem safe, rational, comfortable, easy, but it ends badly, in some futility or in a mere circling down the abyss or in a stagnant morass. Our right and natural road is towards the summits.
Sri Aurobindo
