Vercingetorix was the Gaelic leader who heroically fought the invasion of Celtic Gaul by the Romans in the 1st century BC. He was defeated and imprisoned for six years in the Tullianum, known as The Pit of Dread, a stone cell under Rome. His only contact with the outside world was through a small hole in the top of the pit and those occasions when he was paraded through the streets to be pelted with insults and garbage. After six years, Julius Caesar determined to sacrifice Vercingetorix to the god Mars as part of the celebration of the Great Triumph and the dedication of The Forum. Before putting him to death, Caesar demanded his secret. "I must know how you have kept your sanity and your dignity." How did he endure the loss of his homeland, people, friends, and his beloved Siroma? Vercingetorix' secret is the essence of Celtic spiritual fortitude. Part I resurrects the life of Vercingetorix from the fragments of history. Part II reconstructs the philosophies that sustained him. Vercingetorix' rediscovered wisdom lives on as timeless as ever. The philosophies of the ancient Celts form a guide to self-mastery in today's world. The disciplines taught by the ancient Druids can be referred to today as 'Celtic Cabala' and 'Celtic Yoga'.
