This prayer reveals the right attitude during difficult periods that come in the course of sadhana.
April 20, 1914
AFTER I had hoped so much, after I had come to believe that my outer being was at last to become an instrument adapted to Thy ends, after the hope had come of being delivered at last from this ego, so cumbersome and obscure, I feel as far from the goal as before, as ignorant, as egoistic as I was before this great expectation. And once more the way rolls out interminable across the fields of inconscience. The sublime door is again closed and again I find myself on the threshold of the sanctuary without any power to enter. But I have learnt to regard everything smilingly with a tranquil heart. Only I ask Thee, O my divine Master, not to let me commit errors; even if the instrument is condemned again for a time to inconscience, grant that it may faithfully and docilely let itself be guided by Thy divine law.
I salute Thee, O Lord, with a profound and pure devotion. Oh! be the sovereign Master of all hearts
