It is on account of the ego that one is not able to see God. In front of the door of God's mansion lies the stump of ego. One cannot enter the mansion without jumping over the stump.
RamakrishnaDifferent people call on [God] 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 Moslems 'pani'. But it is one and the same thing.
