Do/try them all!

On the old boards we had many threads on the different types of Reiki that are now "out and about" and being taught. I am familiar with Karuna Reiki as developed by Willam Rand, I've never heard of Karuna-Ki but that is ok too :)

Now, Innerlight, he is the actual originator of "Cupcake Reiki" and can go into great detail if coaxed

In any case, the one thing that I know that develops your "feeling" of the energy is to do as much Reiki as you can.

Good luck and keep us posted!!
