..If you are sincere in all the elements of your being, to the very cells of your body and if your whole being integrally wants the Divine, you are sure of victory but for nothing less than that. That is what I call being sincere.
I am not speaking of glaring things like obeying your impulses, your caprices and then saying: “I do not belong to myself any more, I belong to the Divine; it is the Divine who is doing everything in me, who is acting in me”, that indeed is crude enough. I am speaking of more refined people, a little more noble, who put on a pretty cloak to cover their desires.
How many things in the course of the day, how many thoughts, sensations, gestures are turned exclusively towards the Divine in an aspiration? How many? I believe if you have a single one in the whole day, you may mark that in red letters.
When I say, “If you are sincere, you are sure of victory”, I mean true sincerity: to be constantly the true flame that burns like an offering. That intense joy of existing only by the Divine and for the Divine and feeling that without Him nothing exists, that life has no longer any meaning, nothing has any purpose, nothing has any value, nothing has any interest, unless it is this call, this aspiration, this opening to the supreme Truth, to all that we call the Divine (because you must use some word or other), the only reason for the existence of the universe. Remove that and everything disappears.
