Two and a half millennia ago, a new religion was born in northern India, generated from the ideas of a single man, the Buddha. He was a mysterious Indian sage who famously gained enlightenment while he sat under a big, shapely fig tree. The Buddha never claimed to be God or his emissary on earth. He said only that he was a human being who, in a world of unavoidable pain and suffering, had found a kind of serenity that others could find too.
