 Unlike Lundborg's earlier works, the "Psychedelia" book is expanded to cover a much wider field than music.Psychedelic culture is traced from its beginnings with the hallucinogenic celebrations at Eleusis 2,500 years ago, acknowledging in parallel the ancient shamanic plant drug cultures of South America and Mexico.A permanent alternative spiritual culture of the West is outlined as Lundborg follows the impulse from Eleusis through the Neoplatonism and pantheism of the Middle Ages, the rise of hermeticism and esoteric alchemy during the Renaissance, up to the highly visible psychedelic scenes of the modern world.
