The Cave of the Saints is a spiritual novel centering on Armin Thoms, a downhearted grad student, who is drawn intuitively toward a hidden cave on a ridge behind a café where he has been working on his thesis. In the Cave of the Saints, he encounters mysteriously appearing saints and deities who initiate him into ancient spiritual practices including the Tree of the Heart, the Flame of Golden Light, Touching the Face of Brahman, Seeing Like the Divine Mother, Feeling with the Innermost Self, Becoming Eyeless While Seeing, the Purple Flame, and the Uncarved Stone. Summoned by intuition, the shapeshifting spiritual adept Dona Poireau arrives at the cave to show Armin how to practice these visionary teachings. Through startling changes of perspective initiated by Dona and the saints, Armin overcomes his doubts and enters into the ancient spiritual wisdom of humanity.
