Preserve Energy, Sleeping Is Less Needed

 Yogis sleep less than the normal men, 'coz 1) they don't waste their energy like us and, 2) they preserve lots of energy while doing meditation(dhyan) most-of-the-time.

Thing is, our Pranic Body (Pranamaya Kosha) always creates energy; this energy leaks out through our eyes, fingers of hands and feet, head (crown chakra) -- it leaks or say emanates continuously, majorly from these parts. Also we waste our energy by doing work (mental / physical / emotional) and also by short-and-irregular breathing patterns. Level of energy wastage is directly proportionate to the level of our stress (physical / mental / emotional).

What happens in sleep! It happens that we just preserve our energy by closing our eyes, switching off mind and sense organs and take rest in that -- thus major part of energy is saved. And this is the energy which charges us, we feel charged (invigorated) in the morning.
