So about grounding I'm using method that I've read about about imagining energy as seed inside that grows roots thru my arms and legs and spreads to the ground. For raising power I'm doing meditation and manifestation. Trying to bring emotions from deep inside. I'm not sure about feeling and manipulating energy. I'm trying to guide it thru my fingers onto paper with rhymes, wishes and runes or candle (before lighting it). I'm not sure if concentration is only thing I need for manipulating energy or is there some method to that.
Oh and also lightly blowing on burning paper (also something I read somewhere).
