If one learns from others, but does not think, one will be bewildered. If, on the other hand, one thinks but does not learn from others, one will be in peril.
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.
Yoga means to bind back, unite. To bring the body and the soul together. For this reason the practice of yoga is a holy endeavor and the teaching of it to our people a very high calling.
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.
