Yoga-nidra (Yoga Sleep) is to be defined as the experience of a state of Conscious Sleep in which the subject is showing all the symptoms of deep non-REM sleep, producing delta (1-4 hertz) brain waves, and is at the same time fully conscious of the events in his surroundings. (Swami Veda)   

Swami Rama wrote: “Yoga nidra has immense benefits and can be used for learning the subtleties of life. Only by yoga nidra can one study how the mind slips to dreaming and then goes to deep sleep, how the conscious mind withdraws itself and goes to the lap of the unconscious. The yogis recall all their samskaras, watch them, examine, and even select and reject them according to their need. Those thought patterns that are disturbing are rejected, and those that are helpful are strengthened. With the help and practice of yoga nidra, one can go beyond all the levels of the unconscious.”
