It is weakness, says the Vedanta, which is the cause of all misery in this world. Weakness is the one cause of suffering. We become miserable because we are weak. We lie, steal, kill, and commit other crimes, because we are weak. We suffer because we are weak. We die because we are weak. Where there is nothing to weaken us, there is no death nor sorrow. We are miserable through delusion. Give up the delusion, and the whole thing vanishes. It is plain and simple indeed… This, says the Vedanta, is the only prayer that we should have. This is the only way to reach the goal, to tell ourselves, and to tell everybody else, that we are divine. And as we go on repeating this, strength comes. He who falters at first will get stronger and stronger, and the voice will increase in volume until the truth takes possession of our hearts, and courses through our veins, and permeates our bodies. Delusion will vanish as the light becomes more and more effulgent, load after load of ignorance will vanish, and then will come a time when all else has disappeared and the Sun alone shines.”
