“Sincerity is perhaps the most difficult of all things and perhaps it is also the most effective.
If you have perfect sincerity, you are sure of victory. It is infinitely difficult. Sincerity consists in making all the elements of the being, all the movements (whether outer or inner), all the parts of the being, all of them, have one single will to belong to the Divine, to live only for the Divine, to will only what the Divine wills, to express only the divine Will, to have no other source of energy than that of the Divine.
And you find that there is not a day, not an hour, not a minute when you do not need to intensify, rectify your sincerity — a total refusal to deceive the Divine. The first thing is not to deceive oneself. One knows one cannot deceive the Divine; even the cleverest of the Asuras cannot deceive the Divine. But even when one has understood that, one sees that quite often in one’s life, in the course of the day, one tries to deceive oneself without even knowing it, spontaneously and almost automatically. One always gives favourable explanations for all that one does, for one’s words, for one’s acts. That is what happens first. I am not speaking of obvious things like quarrelling and saying, “It is the other one’s fault”, I am speaking of the very tiny things of daily life.
I know a child who knocked against a door and he gave a good kick to the door! It is the same thing.”
