Swami Vivekananda addresses the 1893 Parliament of the World’s Religions

Chicago Addresses:

"Much has been said of the common ground of religious unity. I am not going just now to venture my own theory. But if anyone here hopes that this unity will come by the triumph of any one of the religions and the destruction of the others, to him I say, 'Brother, yours is an impossible hope.' Do I wish that the Christian would become Hindu? God forbid. Do I wish that the Hindu or Buddhist would become Christian? God forbid.

The seed is put in the ground, and earth and air and water are placed around it. Does the seed become the earth, or the air, or the water? No. It becomes a plant, it develops after the law of its own growth, assimilates the air, the earth, and the water, converts them into plant substance, and grows into a plant.

Similar is the case with religion. The Christian is not to become a Hindu or a Buddhist, nor a Hindu or a Buddhist to become a Christian. But each must assimilate the spirit of the others and yet preserve his individuality and grow according to his own law of growth."
