The importance of ancient Indian literature as a whole largely consists in its originality. Naturally isolated by its gigantic mountain barrier in the north, the Indian peninsula has ever since the Aryan invasion formed a world apart, over which a unique form of Aryan civilisation rapidly spread, and has ever since prevailed.
