The power of desire

Desire, when it stems from the heart and spirit, when it is pure and intense, possesses awesome electromagnetic energy. This energy is released into the ether each night, as the mind falls into the sleep state. Each morning it returns to the conscious state reinforced with the cosmic currents. That which has been imaged will surely and certainly be manifested. You can rely, young man, upon this ageless promise as surely as you can rely upon the eternally unbroken promise of sunrise… and of Spring.

~ Swami Sivananda (8 Sept 1887 — 14 July 1963)
(as quoted by Abdul Kalam)

That, without which we cannot live, must come to us

So, when the desire will arise to have a peaceful, quiet life, that shall come where everything shall be propitious for the development of the mind—you may take that as my experience. It may come after thousands of lives, but it must come. Hold on to that, the desire. You cannot have strong desire if its object was not outside for you already. Of course, you must understand, there is a difference between desire and desire. The master said, "My child, if you desire after God, God shall come to you." The disciple did not understand the master fully. One day both went to bathe in a river, and the master said, "Plunge in", and the boy did so. In a moment, the master was upon him, holding him down. He would not let the boy come up. When the boy struggled and was exhausted, he let him go. "Yes, my child, how did you feel there?" "Oh, the desire for a breath of air!" "Do you have that kind of desire for God?" "No, sir.' "Have that kind of desire for God, and you shall have God."

That, without which we cannot live, must come to us.

~ Swami Vivekananda (Complete Works, Vol. 5, p.250-251)
