In this classic text, famed historian of religion Mircea Eliade attempts to describe how religious people experience the sacred, and even how moderns who proclaim themselves residents of a completely profane world are still unconsciously nourished by the memory of the sacred.

Eliade also gives a fascinating explanation of primitive religions. The popular image of the religion of primitive peoples is pretty unflattering: they worship rocks, animals, and whatnot; their rituals are just attempts to extract favors from imaginary spirits; their myths are laughably bad attempts at scientific explanations, etc. Eliade shows that these are complete misunderstandings. Primitive people don't worship natural objects, but they believe that natural objects can be revelations of the sacred, and that one can worship the gods through them. 

Primitive men certainly do want help from their gods (who wouldn't?), but they are also driven by what Eliade calls an 'ontological nostalgia', a desire to live in the presence of the gods who are the preeminently real and the source of all being. Nor do their myths seem so silly when one understands the function they serve and the universal symbolism they employ.

Eliade was the Sewell L. Avery Distinguished Service Professor at the Divinity School and professor in the Committee on Social Thought at the University of Chicago. He was one of the most influential scholars of religion of the 20th century and one of the world's foremost interpreters of religious symbolism and myth. Eliade was the author of many works of scholarship and fiction, including A History of Religious Ideas and ten novels.
