This prayer reveals to us the essence of the Integral yoga.
May 22, 1914
WHEN we have discerned successively what is real from what is unreal in all the states of being and all the worlds of life, when we have arrived at the perfect and integral certitude of the sole Reality, we must turn our gaze from the heights of this supreme consciousness towards the individual aggregate which serves as the immediate instrument of Thy manifestation upon earth, and see in it nothing but Thee, our sole real existence. Thus each atom of this aggregate will be awakened to receive Thy sublime influence; the ignorance and the darkness will disappear not only from the central consciousness of the being but also from its most external mode of expression. It is only by the fulfilment, by the perfection of this labour of transfiguration that there can be manifested the plenitude of Thy Presence, Thy Light and Thy Love.
Lord, Thou makest me understand this truth ever more clearly; lead me step by step on that path. My whole being down to its smallest atom aspires for the perfect knowledge of Thy Presence and a complete union with it. Let every obstacle disappear, let Thy divine knowledge replace in every part the darkness of the ignorance. Even as Thou hast illumined the central consciousness, the will in the being, enlighten too this outermost substance. And let the whole individuality, from its first origin and essence to its last projection and most material body, be unified in a perfect realisation of Thy sole Reality.
Nothing is in the universe but Thy life, Thy light, Thy love.
Let everything become resplendent and transfigured by the knowledge of Thy Truth.
Thy divine love floods my being; Thy supreme light is shining in every cell; all exults because it knows Thee and because it is one with Thee.”
The text above is quoted from the Third Edition, 1954 (translation by Rishabhchand Samsukha)
