Yoga Nidra is an ancient sleep-based meditation technique that has the power to take you to the innermost, deepest levels of relaxation where your whole body and being is permeated by peace of mind and profound stillness. It unlocks the mystical, integrative powers of the subconscious, as well as your higher centers of consciousness, to effortlessly erase your most tenacious, self-destructive habits and behavior patterns. It is said by yogis that 45 minutes of Yoga Nidra is as restorative as three hours of sleep.
