The 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.
The one aim of [my] yoga is an inner self-development by which each one who follows it can in time discover the One Self in all and evolve a higher consciousness than the mental, a spiritual and supramental consciousness which will transform and divinize human nature.
Great compassion penetrates into the marrow of the bone. It is the support of all living beings. Like the love of a parent for an only child, the tenderness of the Compassionate One is all-pervasive.
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.
