Talk of surrender or a mere idea or tepid wish for integral consecration will not do; there must be the push for a radical and total change.

It is not by taking a mere mental attitude that this can be done or even by any number of inner experiences which leave the outer man as he was. It is this outer man who has to open, to surrender and to change. His every least movement, habit, action has to be surrendered, seen, held up and exposed to the divine Light, offered to the divine Force for its old forms and motives to be destroyed and the divine Truth and the action of the transforming consciousness of the Divine Mother to take their place.
