 I started practicing yoga at the age of eleven. Ever since then it doesn't matter where I am. The first time when I wake up, when I check the time, it's always around, just before 340, always. Because once you do certain things with your system that it's in sync, your biology is in sync with the biology of the planet, 340 you will realize is not a concocted time that somebody came up with. There is something within the system which is ticking with the planet which will make you come awake. So this was identified as the best time for one to do practice if he wants to transcend his physical nature or know different dimensions of what we are referring to as spiritual.
