There is more than one type of Reiki. Actually, it would be better to say there are many thoughts of and types of Reiki. They do all have one thing in common... energy. We could say that for everything in reality, but Reiki is a tool or method used in Energy Healing.
As we discussed in the other areas on this site, energy is everywhere, all around us and never dies. Instead it transfers and transforms. With Reiki we learn to transfer energy through one to another. Notice I didn't say FROM. We learn to transfer energy through ourselves. This part is important so really think about this. Learning methods and techniques is protection for ourselves. There is enough energy in this amazing universe we live in for us all. So, we learn ways to let the negative energy bounce off and only absorb the pure high energy.
Remember this too, energy has no time or distance limitation. This is another thing Reiki teaches us. Remote healing is when there is distance between the Reiki practitioner and person receiving energy. It may seem off the wall to some and I get that for sure. It can also be tough to understand or appreciate until you experience or witness it first-hand. My suggestion would be to search for local meetings. The app Meetup is a great place to start.
The focus of this site to pull together multiple methods, techniques and tools to help us reach our ultimate goal. Reiki techniques can play a part.
