I'm not sure if anyone here has mentioned Robert Bruce's New Energy Ways (NEW) techniques that focus on tactile energy sensation as opposed to visualization. His book Astral Dynamics changed my life in terms of energy work. He'll have a new book out this summer called something simple like "Energy Ways" that I'm looking forward to.
He has a free tutorial about NEW on his site
