Yoga Nidra is a deep relaxation process that takes the listener through different levels of relaxation: muscular, mental, emotional, and energetic. It is a form of meditation that involves the whole brain and body of the practitioner. Yoga Nidra loosely translates in to sleep with a trace of awareness. While this Yoga Nidra practice can be used to improve sleep, for best results work toward remaining awake, with just a trace of awareness.
