The personal will of the sadhaka has first to seize on the egoistic energies and turn them towards the light and the right; once turned, he has still to train them to recognise that always, always to accept, always to follow that. Progressing, he learns, still using the personal will, personal effort, personal energies, to employ them as representatives of the higher Power and in conscious obedience to the higher Influence. Progressing yet farther, his will, effort, energy become no longer personal and separate, but activities of that higher Power and Influence at work in the individual. But there is still a sort of gulf or distance which necessitates an obscure process of transit, not always accurate, sometimes even very distorting, between the divine Origin and the emerging human current. At the end of the process, with the progressive disappearance of egoism and impurity and ignorance, this last separation is removed; all in the individual becomes the divine working.
It is certain that one's own effort is necessary, though one cannot do the sadhana by one's own effort alone. The Mother's Force is needed, but the sadhak must open himself to it, reject what opposes the Force, put his full sincerity, aspiration, will power into the sadhana. It is only when all is open and there is the full surrender that the Divine Power takes up the sadhana so entirely that personal effort is no longer necessary. But that cannot happen at an early stage—one must go on opening oneself, consecrating oneself, making the surrender till that later stage comes. <ref>https://incarnateword.in/cwsa/32/receptivity-and-openness-to-the-mothers-force#p23</ref>
For a time comes in spiritual development when we become aware that all our effort and action are only our mental and vital reactions to the silent and secret insistence of a greater Presence in and around us. It is borne in upon us that all our Yoga, our aspiration and our endeavour are imperfect or narrow forms, because disfigured or at least limited by the mind's associations, demands, prejudgments, predilections, mistranslations or half translations of a vaster truth. Our ideas and experiences and efforts are mental images only of greatest things which would be done more perfectly, directly, freely, largely, more in harmony with the universal and eternal will by that Power itself in us if we could only put ourselves passively as instruments in the hands of a supreme and absolute strength and wisdom. That Power is not separate from us; it is our own self one with the self of all others and at the same time a transcendent Being and an immanent Person. Our existence, our action taken up into this greatest Existence would be no longer, as it seems to us now, individually our own in a mental separation. It would be the vast movement of an Infinity and an intimate ineffable Presence; it would be the constant spontaneity of formation and expression in us of this deep universal self and this transcendent Spirit.
