A total spiritual direction given to the whole life and the whole nature can alone lift humanity beyond itself. . . It is only the full emergence of the soul, the full descent of the native light and power of the Spirit and the consequent replacement or transformation and uplifting of our insufficient mental and vital nature by a spiritual and supramental Supernature that can effect this evolutionary miracle.
The seers of ancient India had, in their experiments and efforts at spiritual training and the conquest of the body, perfected a discovery which in its importance to the future of human knowledge dwarfs the divinations of Newton and Galileo , even the discovery of the inductive and experimental method in Science was not more momentous.
Even if the being is not entirely purified, varieties of inspirations and powers may come down from above but this may lead to serious errors. Inspirations from above mixing with the impurities from below get all muddled up and the sadhak takes this for an absolute command. Many a sadhak has thus fallen into danger. Therefore, one must particularly lay stress on the purification of the being.
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.
Spirituality is much wider than any particular religion, and in the larger ideas of it that are now coming on us even the greatest religion becomes no more than a broad sect or branch of the one universal religion, by which we shall understand in the future man's seeking for the eternal, the divine, the greater self, the source of unity and his attempt to arrive at some equation, some increasing approximation of the values of human life with the eternal and the divine values.
Spirituality is the master key of the Indian mind. It is this dominant inclination of India which gives character to all the expressions of her culture. In fact, they have grown out of her inborn spiritual tendency of which her religion is a natural out flowering. The Indian mind has always realized that the Supreme is the Infinite and perceived that to the soul in Nature the Infinite must always present itself in an infinite variety of aspects.
There is therefore no reason to put a limit to evolutionary possibility by taking our present organization or status of existence as final. The animal is a laboratory in which Nature has worked out man; man may very well be a laboratory in which she wills to work out superman, to disclose the soul as a divine being, to evolve a divine nature.
All religions have some truth in them, but none has the whole truth; all are created in time and finally decline and perish. Mahomed himself never pretended that the Koran was the last message of God and there would be no other. God and Truth outlast these religions and manifest themselves anew in whatever way or form the Divine Wisdom chooses.
