Yoga Nidra, which is derived from the tantras, is a powerful technique in which you learn to relax consciously. In yoga nidra, sleep is not regarded as relaxation. People feel that they are relaxing when they collapse in an easy chair with a cup of coffee, a drink or a cigarette, and read a newspaper or switch on the television. But this will never suffice as a scientific definition of relaxation. These are only sensory diversions. True relaxation is actually an experience far beyond all this. For absolute relaxation you must remain aware. This is yoga nidra, the state of dynamic sleep.
