The simplest explanation is to say, modality is the method chosen by a particular energy healer to affect change in others. When you begin it can all seem over whelming... there are hundreds of modalities and dozens of variations on each. Just explore what (and who) is out there... sample a bit of everything until you find what feels right for you. Do not buy into the hype or success stories... ask yourself does this (whatever) make sense to you ...will you actually DO the program. I am A.D.D. and anything that requires weeks of daytime attention isn't going to happen. I have my best success with short seminars, also brainwave entrainment and / or hypnosis. 
          We are born with everything we need to be happy, healthy, well-adjusted and have everything we need or want from life.  Unfortunately , much of that knowledge was trained out of us growing up physical beings. Once we unlock the memories of our spiritual being we become empowered once again by Divine energy and wisdom.
