Conscious deep relaxation is a priceless skill, a life skill even! It is not sleeping and it is not your usual end-of-a-yoga-class-relaxation. Rather it is a focused, systematic withdrawal of consciousness from the outside world to the deepest part of your being. Thirty minutes of yoga nidra is said to equal 3 to 4 hours of sleep! I personally have experienced the benefits of yoga nidra and can attest to its fast rejuvenating power. Unfortunately, when tired many of us turn to unwinding methods that hardly rejuvenate us, if at all.
