The Rigveda is a monumental text in both world religion and world literature, yet outside a small band of specialists it is little known. Composed in the latter half of the second millennium BCE, it stands as the foundational text of what would later be called Hinduism. The text consists of over a thousand hymns dedicated to various divinities, composed in sophisticated and often enigmatic verse. This concise guide from two of the Rigveda's leading English-language scholars introduces the text and breaks down its large range of topics—from meditations on cosmic enigmas to penetrating reflections on the ability of mortals to make contact with and affect the divine and cosmic realms through sacrifice and praise—for a wider audience.
