It is not good to feel that one’s own religion alone is true and all others are false. God is one only, and not two. Different people call on Him by different names: some as Allah, some as God, and others as Krishna, Siva, and Brahman. It is like the water in a lake. Some drink it at one place and call it ‘jal’, others at another place and call it ‘pani’, and still others at a third place and call it ‘water’. The Hindus call it ‘jal’, the Christians ‘water’, and the Mussalmans ‘pani’. But it is one and the same thing. Opinions are but paths. Each religion is only a path leading to God, as rivers come from different directions and ultimately become one in the one ocean.
—Sri Ramakrishna
