From my experience and be involved in Reiki for 7 years I have seen many people from all around the world coming here to learn. Many of them arrive with what they call "be already a master" and at the beginning master Lee Wei De ask me to give them a healing session and I always was thinking at that time, why does he want me to make them a session they already master from somewhere and I was level one. After the session many time the so called master tell me Whaou how can you do that your energy is so strong. Two of them even fall to the ground after the session just before the grounding. So my deep belief is the way you get taught is very important and also the less is going on in your head during a session is the best. I always think at the beginning of the session I am like a pipeline catching the universal energy and direct it to the body in front of me. After that, I really try to not thinking and the result is always good. Cancer is a problem with Reiki as when you are dealing with it, it also takes advantage of the energy you are sending the food is working really great for it since the people not been treated with chemo before. Thanks for your post.
