Yoga Nidra is a deep relaxation practice. It systematically relaxes the whole body and mind. It rejuvenates and liberates energy deep within the tissues it also has the powerful potential to strengthen and expand consciousness.

Yoga Nidra was constructed by Swami Satyananda about 35 years ago. The development of yoga nidra incorporated features from the tantric practice called nyasa. Nyasa was a practice whereby the practitioner mentally placed mantras within the body parts, this rotation of consciousness throughout the body inspired the similar stage in yoga nidra.

The Yoga Nidra practice exists today with 8 clearly defined stages; some stages of the Yoga Nidra practice deepen pratyahara. Pratyahara is an effect as well as a state which is induced by the withdrawal of awareness from sensory perception. Yoga Nidra is best done as a guided practice, that is, with an experienced yoga teacher who verbally delivers the instructions.
