Hi,
Welcome to the cafe and congratulations on the beginning of your Reiki journey :)
It depends from person to person some feel the flow immediately and others take a little while longer. But the more you practice Reiki the more you will feel it and the differences in your hands. The less expectations you have the better, just go with the flow, practice, practice and practice some more. Oh yes and above all enjoy! :)
You might find it helpful to keep a journal, that way you get to see how far you have come and remember the experiences that you have had.
Let us know how it goes :)
Gentle Blessings
Helen
