The path of knowledge is the well-known path of Raja Yoga, in which one practises detachment from one’s physical being, saying, “I am not the body”, then detachment from one’s sensations, “I am not my sensations”, then from one’s feelings, saying, “I am not my feelings”, and so on. One detaches oneself from thought and goes more and more within until one finds something which is the Eternal and Infinite.

The yoga of knowledge is the path that leads to the Divine through the exclusive pursuit of the pure and absolute Truth.

The first necessity of preparation is the purifying of all the members of our being; especially, for the path of knowledge, the purification of the understanding, the key that shall open the door of Truth; and a purified understanding is hardly possible without the purification of the other members. An unpurified heart, an unpurified sense, an unpurified life confuse the understanding, disturb its data, distort its conclusions, darken its seeing, misapply its knowledge; an unpurified physical system clogs or chokes up its action. There must be an integral purity.

But whatever the aim, the path of knowledge must lead to one first result, an absolute quietude; for unless the old action of Nature in us be entirely quieted, it is difficult if not impossible to found either any true soul-status or any divine activity. Our nature acts on a basis of confusion and restless compulsion to action, the Divine acts freely out of a fathomless calm. Into that abyss of tranquillity we must plunge and become that, if we are to annul the hold of this lower nature upon the soul.

The integral Yoga of knowledge has to recognise the double nature of this manifestation, — for there is the higher nature of Sachchidananda in which He is found and the lower nature of mind, life and body in which He is veiled, — and to reconcile and unite the two in the oneness of the illumined realisation. We have not to leave them separate so that we live a sort of double life, spiritual within or above, mental and material in our active and earthly living; we have to re-view and remould the lower living in the light, force and joy of the higher reality.

All relations in the world, even to its greatest and most shocking apparent discords, are relations of something eternal to itself in its own universal existence; they are not anywhere or at any time collisions of disconnected beings who meet fortuitously or by some mechanical necessity of cosmic existence. Therefore to get back to this eternal fact of oneness is our essential act of self-knowledge; to live in it must be the effective principle of our inner possession of our being and of our right and ideal relations with the world. That is why we have had to insist first and foremost on oneness as the aim and in a way the whole aim of our Yoga of knowledge.

The realisation of the Yoga of Knowledge is when one feels that one lives in the wideness of something silent, featureless and universal (called the Self) and all else is seen as only forms and names; the Self is real, nothing else.

Contemplation of God in Nature, contemplation and service of God in man and in the life of man and of the world in its past, present and future, are equally elements of which the Yoga of knowledge can make use to complete the realisation of God in all things.
