Yoga Nidra means Yogic Sleep. It is a state of conscious Deep Sleep. In Meditation, you remain in the Waking state of consciousness, and gently focus the mind, while allowing thought patterns, emotions, sensations, and images to arise and go on. However, in Yoga Nidra, you leave the Waking state, go past the Dreaming state, and go to Deep Sleep, yet remain awake. While Yoga Nidra is a state that is very relaxing, it is also used by Yogis to purify the Samskaras, the deep impressions that are the driving force behind Karma.

Yoga Nidra brings an incredible calmness, quietness and clarity. Yoga Nidra is one of the deepest of all meditations, leading awareness through many levels of mental process to a state of supreme stillness and insight. With patient and thorough reading [of the Yoga Nidra article], the understanding is well worth the effort, allowing you to see the profound depth of Yoga Nidra, which is far beyond just relaxation. It is said that a picture is worth a thousand words. Sometimes it takes thousands of words to get the inner "aha" of the meaning. Most important of all, it is the persistent practice that brings the real joy of the practice of Yoga Nidra, as with all useful practices in life and Yoga.
