Swami Vivekananda thought that man has been searching the spiritual entities such as destiny, soul, God, etc., and this searching is being represented by different world religions competing and quarrelling to each other by declaring the absolute empire in the arena of religion and consequently by claiming the ‘exclusive right to live’. It is this kind of attitude that gives birth to hatred, war, conflict, tension and so on. Vivekananda believes in the diversity of life and calls it the law of life without which variations in thought is not possible. Keeping this in mind, he says that though throughout the ages, people of different religions have been trying to prove their “exclusive right to live”, though they have been claiming that one’s own religion is absolutely true, but none of them has been able to make success in this matter. He firmly asserts that, it is a serious mistake and quite impossible to make all people think in a single mode about spiritual things. In his own words, “…any attempt to bring all humanity to one method of thinking in spiritual things has been a failure and always will be a failure”. He emphasizes that though religions are divergent in various aspects, they are not contradictory, rather supplementary to each other. The differences amongst religions are external parts only which are due to our birth, education, surroundings and so on; but internally each religion bears the ideal which is its unique feature and soul; the soul of one may differ from that of other religion, nevertheless, they are not contradictory, both are parts of the same universal truth.
