there are many ways to do this but the way that works best for me is to close my eyes and relax my body and just fill myself with a void, feeling energy pull into me from the world around me everything has energy in and through it so it is not hard to gain energys easyly wherever you may be. just pull it into yourself and feel your body become more and more energized. the void filling up with excited energys and open your eyes relaxed and happy.
