Self-surrender is the condition of the perfect working of Grace. It may be partial or complete; but in any case it tends towards Egolessness, and anticipates in some measure all the good that there is in Egolessness. The surrenderer, says the Sage, need not worry about his own good and evil actions of the past; their reaction would not work to his disadvantage; for Grace would dispose of them so as to turn them to his advantage. The whole function of Grace is the elimination of the sheaths, after which the real self alone will remain.
Grace is not something special; it is really universal; it is the only power for good there is, and all alike participate in its goodness; but the ego interferes and discounts its work; by self surrender this interference is made less and less, and the work of Grace becomes more and more effective.
...The Sage was asked by someone what he should do to deserve Grace; the Sage answered; "Are you asking this question without Grace? Grace is in the beginning, the middle and the end; ; for Grace is the Self; but because of ignorance of the Self it is expected to come from somewhere outside of you."
