I was just wondering about what exactly Rheki is and how it can be used for enlightment and spiritual development?
Perhaps you mean Reiki?

For me it's like being a spiritual yonkie. While helping others pushing their energy blockages you feel as being really up.
You also see all in terms of karma, more after analyzing what happens to some subjects' lives after having been experienced some reiki cure.
And in terms of subtle energies you learn controlling, feeling and applying them.
Ah!, and you get more detached from physical things, and you start to trust the universe.
(all of this from my viewpoint, of course. Maybe other reiki masters act differently).
Thanks for your reply, it was quite intriguing.
