To get control of your thoughts, self-denial is necessary. It means voluntarily giving up that which the mind likes. It is a means of refining the mind. Self-denial purifies and stills thought-waves. Unless all the thoughts are stilled and the mind is made calm, knowledge of God cannot dawn.
The God who cannot respond does not evoke satisfaction in the heart. The God who includes us, outside Whom we cannot even exist, need not give any response at all. But our heart says: “I love God. Maybe I love Him as an all-pervading essence, but even then I require a response. I should know that He knows that I love Him.” The question of expecting this kind of response from God, blessing from God, grace from God, or protection from God—anything whatsoever from God—cannot arise in a case where the person who expects this response cannot stand outside the One from whom the response has to come.
