Concentration is indeed the first condition of any Yoga, but it is an all-receiving concentration that is the very nature of the integral Yoga. A separate strong fixing of the thought, of the emotions or of the will on a single idea, object, state, inner movement or principle is no doubt a frequent need here also; but this is only a subsidiary helpful process. A wide massive opening, a harmonised concentration of the whole being in all its parts and through all its powers upon the One who is the All is the larger action of this Yoga without which it cannot achieve its purpose. For it is the consciousness that rests in the One and that acts in the All to which we aspire; it is this that we seek to impose on every element of our being and on every movement of our nature. This wide and concentrated totality is the essential character of the Sadhana and its character must determine its practice.
