Hinduism is the religion of the Hindus, a name given to the Universal Religion which hailed supreme in India. It is the oldest of all living religions. This is not founded by any prophet. Buddhism, Christianity and Mohammedanism owe their origin to the prophets. Their dates are fixed. But no such date can be fixed for Hinduism. Hinduism is not born of the teachings of particular prophets. It is not based on a set of dogmas preached by a particular set of teachers. It is free from religious fanaticism. Excerpt from All About Hinduism by Sri Swami Sivananda
