"Ploughing the Clouds" by Wilson
Plant Powers, Poisons and Herbcraft" The Rig Veda, written in India about 1500 BC, praises a holy plant called Soma (or "magic mushroom"), which is sacrificed and consumed, granting the drinker an experience of enlightenment and ecstasy. In Ploughing the Clouds Peter Lamborn Wilson investigates the probability of a Soma cult in ancient Ireland, tracing clues in Irish (and other Celtic) lore. By comparing Celtic foktales, romances,epics and topographic lore with the Rig Veda, he uncovers the Irish branch of the great Indo-European tradition of psychedelic shamanism, and even reconstructs some of its secret rituals. He uses this comparitive material to illuminate the deep meaning of the Soma-function in all cultures: the entheogenic origin of "poetic frenzy", the link between intoxication and inspiration.
