The festival has its origin in a traditional Buddhist tale. When Prince Vessadorn, the Buddha's penultimate incarnation, returned to his city, the welcoming procession was so delightful that spirits emerged to celebrate.
Phi Ta Khon is celebrated largely by young men who dress as spirits to parade a sacred Buddha image and tease villagers, and monks reciting the story of the Buddha's last great incarnation before attaining Enlightenment.
