bring in the light

If the room is dark, the constant feeling and repeating of darkness will not take it away, but bring in the light. Let us know that all that is negative, all that is destructive, all that is mere criticism, is bound to pass away; it is the positive, the affirmative, the constructive, that is immortal, that will remain for ever. Let us say, " We are" and "God is", and "We are God","Shivoham Shivoham", and march on. Not matter, but spirit. All that has name and form is subject to that has none. This is the eternal truth the shrutis preach. Bring in the light; the darkness will vanish of itself. Let the lion of vedanta roar; the foxes will fly to their holes. Throw the ideas broadcast, and let the result take care of itself. Let us put the chemicals together; the crystallisation will take its own course. Bring forth the power of the spirit, and pour it over the length and breadth of India, all that is necessary will come by itself.
Manifest the divinity within you, and everything will be harmoniously arranged around it. Remember the illustration of Indira and Virochana in the vedas; both were taught their divinity. But the Asura, Virochana, took his body for his God. Indira being a Deva, understood that the Atman was present. You are the children of Indra. You are the descendants of the Devas. Matter can never be your God; body can never be your God.
