ANSWER: We assume that all religions must have founders. And all the major religions of the world, except one, do have founders. Jesus Christ is the founder of Christianity; Prophet Mohamed is the founder of Islam; and Gautama Buddha is the founder of Buddhism. But Vedanta does not have a known founder.
Soft-brained people, weak-minded, chicken-hearted, cannot find the truth. One has to be free, and as broad as the sky.— Swami Vivekananda
