Our purpose in Yoga is to exile the limited outward-looking ego and to enthrone God in its place as the ruling Inhabitant of the nature. And this means, first, to disinherit desire and no longer accept the enjoyment of desire as the ruling human motive. The spiritual life will draw its sustenance not from desire but from a pure and selfless spiritual delight of essential existence. And not only the vital nature in us whose stamp is desire, but the mental being too must undergo a new birth and a transfiguring change. Our divided, egoistic, limited and ignorant thought and intelligence must disappear; in its place there must stream in the catholic and faultless play of a shadowless divine illumination which shall culminate in the end in a natural self-existent Truth-consciousness free from groping half-truth and stumbling error. Our confused and embarrassed ego-centred small-motived will and action must cease and make room for the total working of a swiftly powerful, lucidly automatic, divinely moved and guided unfallen Force. There must be implanted and activised in all our doings a supreme, impersonal, unfaltering and unstumbling will in spontaneous and untroubled unison with the will of the Divine. The unsatisfying surface play of our feeble egoistic emotions must be ousted and there must be revealed instead a secret deep and vast psychic heart within that waits behind them for its hour; all our feelings, impelled by this inner heart in which dwells the Divine, will be transmuted into calm and intense movements of a twin passion of divine Love and manifold Ananda. This is the definition of a divine humanity or a supramental race. This, not an exaggerated or even a sublimated energy of human intellect and action, is the type of the superman whom we are called to evolve by our Yoga.
