There will always be doubts, upsettings and confusion of the physical mind and vital, so long as the vital approaches the Mother from the wrong standpoint,— e.g. if it insists on judging her by her response to its demands and ideas of what she ought to give it. Not to impose one’s mind or vital will on the Divine but to receive the Divine’s Will and follow it, is the true attitude of sadhana. Not to say “This is my right, want, claim, need, requirement, why do I not get it?”, but to give oneself, to surrender and to receive with joy whatever the Divine gives, not grieving or revolting, is the right way. Then what one receives will be the right thing for one.
