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 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.
Swami VivekanandaMeditation, you know, comes by a process imagination. You go through all these processes purification of the elements - making the one melt the other, that into the next higher, that into mind, that into spirit, and then you are spirit.
Swami VivekanandaWhat do we call the river? Every moment the water is changing, the shore is changing, every moment the environment is changing, what is the river then? It is the name of this series of changes.
