Similar to traditional Yoga Nidra, Sound Nidra is designed to invoke yogic sleep or deep calming of the mind. In a Sound Nidra session, live musicians rooted in Indian Classical Music accompany supported yoga postures that progressively open and unwind various territories of the physical and subtle body. The progression of both postures and sound offers a journey through layers of psyche, emotion, consciousness, and existential experience. Instrumentation typically includes the Indian bansuri (bamboo) flute, voice, gongs, tuning forks, sitar, tabla, frame drum and other percussion instruments.
