Swami Vivekananda on Universal Religion
You hear claims made by every religion as being the universal religion of the world. Let me tell you in the first place that perhaps there never will be such a thing, but if there is a religion which can lay claim to be that, it is only our religion and no other, because every other religion depends on some person or persons. All the other religions have been built round the life of what they think a historical man; and what they think the strength of religion is really the weakness, for disprove the historicity of the man and the whole fabric tumbles to the ground. Half the lives of these great founders of religions have been broken into pieces and the other half doubted very seriously. As such every truth that had its sanction only in their words vanishes into air. But the truths of our religion, although we have person by the score, do not depend on them.
