Really, it has nothing to do with Reiki, per se...but just in general when touching someone...doing their hair,
shaking hands...rinse your hands up to your forearms and sweep the water and their energy away down the drain
and shake your hands in the air ---downwards.
Sorry no time to get into why...you'll fig it out.
No salt or soap needed from my experience of 40 yrs doing body work...as far as their energy...germs are
a diff thing!
