In this commentary on verse 24 of the Vijnana Bhairava, a classic text of the nondual Shaivism of Kashmir, Swami Muktananda teaches about the power and practice of the hamsa mantra-the mantra that arises naturally and spontaneously with the breath. Swami Muktananda reveals the mystical secrets of this form of mantra repetition and explains how, through dedicated practice, one becomes established in the unwavering experience of inner divinity. The book includes an introduction by Gurumayi Chidvilasananda, the spiritual head of the Siddha Yoga path.
