In religious terms, the human narrative — birth, life, death and rebirth — has for millennia been relatively straightforward in the West. You were born. You lived. You died. After a judgment you went to heaven (or hell) forever and ever. Eternity was the end: no appeals allowed.

But nearly a billion Hindus and a half-billion Buddhists — not to mention the ancient Greeks, certain Jews and a few Christians — have for thousands of years believed something entirely different. Theirs is, as the theologians say, a cyclical view. You are born. You live. You die. And because nobody’s perfect, your soul is born again — not in another location or sphere, and not in any metaphorical sense, but right here on earth.
