Yoga Nidra then takes this restful state even further to what is known as Yogic Sleep. It is a meditation and conscious relaxation practice that is intended to induce total physical, mental and emotional relaxation. It is said that an hour of Yoga Nidra can be as restorative as up to four hours of regular sleep. “Yoga nidra is the yoga of aware sleep. In this lies the secret of self healing. Yoga Nidra is a pratyahara technique in which the distractions of the mind are contained and the mind is relaxed.” Satyananda Saraswati
