What is Reiki?

What is Reiki? As a Reiki master and Practitioner, I have a hard time answering this question myself. I have done many many sessions on many different people. But still, I can find it hard to explain exactly what it is to someone who has no idea. The best answer I could come up with is you just need to experience it to understand it! Although I realize that's not going to hook many people ! I'll start off explaining it in a more tangible way. 
As we are living breathing beings, we are also made up of energy, this is scientifically proven. Each one of us has our own frequency, and our own "vibe" if you will. Reiki, is life force energy. Everything that is alive or is an organic substance has this life force energy within it. Bare with me here, we as humans also have many energy centers in our body, as well as an aura that surrounds us, that reflects the energy we are around us in a egg like shape. Some people have the ability to see these or feel these, I personally can do both. There are 7 major energy centers in the body, these are called chakras. Each chakra is associated with certain parts of the body, for example the crown is the top of the head, the third eye is between your eyes, the throat is at the throat, the heart at the heart, the solar plexus at the stomach, the sacral at the pelvis and the root at the anus. There are also sub chakras at the palms of the hands, the hips, knees, ankles and feet. There are about 120 + chakras in all, but we won't get into that right now. 
Reiki is a way to rebalance the energy centers in the body and field and repair and expand the aura. Why might one want to do this you may be asking? When there is something physically wrong, thats the last part of the problem shows up, and sometimes it can be too late to repair it. When you do reiki, you are healing things before they can reach your physical plane. You are literally putting in pure life force energy into your mind, body and soul. Not to mention how amazing you feel after the session! Getting Reiki done lowers your blood pressure, lowers your pulse an induces good feeling endorphins in the body giving you a feeling a complete peace and relaxation. And all you have do for a session is lay there, the practitioner does the rest. 
During a reiki session, the client remains fully clothed, and the practitioner simply lays their hands on the client. Reiki can also be done by a distance, since we are all made of energy, and time and distance don't exist in the energetic field, the client ill feel the same effects of a session in person or via distance. 

I started doing reiki about 10 years ago, and I have since then become a Reiki Master and Practitioner. I am also Catholic and always bring my faith into each session, calling in assistance from the angels and saints, and of course Jesus and the Holy Spirit and the Holy Fire. I also teach Reiki, and other classes about natural healing and health!
