God is not a necessity in this world. Scientific laws are a necessity--without them the world cannot be. God is not a necessity that way. Without him the world can be, but it will be worthless. Without him you can exist, but your existence will be just a vegetable existence. Without him you can vegetate, you cannot be really alive. God is not a necessity--you can be there, but your being there will not be of any meaning, it will not carry any meaning at all. It will have no poetry, it will have no song, it will have no dance to it, it will not be a mystery. It may be an arithmetic, it may be a business, but it cannot be a love affair. Without God all that is beautiful disappeares, because the beautiful comes only as an overflowing--it is a luxury...And I tell you that God is the most luxurious thing in the world. God is not necessary--you can live without him, you can live very well, but you will miss something, you will feel an emptiness in the heart. You will be more like a wound than an alive force, you will suffer, there cannot be any ecstasy in your life.
