Yoga nidra, a Sanskrit term meaning "yogic sleep" is a deep relaxation technique and a form of meditation.
Also called "psychic sleep," yoga nidra is a state between sleeping and waking. The body is completely relaxed and the practitioner turns the awareness inward by listening to a set of instructions; much like a guided meditation. Performing yoga nidra involves practicing pratyahara ("withdrawal of the senses"), which is the fifth limb of Ashtanga yoga.
Yoga nidra practice results in deep relaxation and expands the individual's self-awareness.
Yoga nidra was practiced by ancient sages so they could consciously watch their samskaras, or the "impressions of the mind." They could also purify their samskaras in order to come closer to liberation, or moksha.
The practice of yoga nidra not only involves pratyhara, but also requires pranayama (breathing techniques) and dharana ("concentration"), which are the fourth and sixth limbs of Ashtanga yoga.
In yoga nidra, the practitioner enters their alpha state and their focus shifts to the third eye chakra(sahasrara). It also stimulates the hormones in the pineal gland, which releases melatonin -- a horomone that reduces stress, boosts the immune system and helps prevent illness. Regular practice helps harmonize the brain hemispheres, promoting better mental performance.
