This text book of Hindu Religion and Ethics, first published in 1914-15, was intended to provide systematic instruction in those principles of Hinduism which may be regarded as common to all sects. Sanatana-Dharma means the Eternal Religion, the ancient Law. It is based on the Veda's, sacred books given to people ages ago.
This religion has also been called the Aryan Religion. In later days, the religion was called the Hindu Religion, and this is the name by which it is now usually known. It is the oldest of all living Religions. Every person irrespective of caste or creed should read it at least for once.
