Reiki energy healing is the gentle laying
or hovering of hands to transfer
universal life force energy ("reiki")
into a receiver.  

This energy integrates with the receiver's
energy body which has a trickle-down, balancing effect on their mental, physical
and emotional bodies.

Jessie describes it as
"superconscious, unconditional love", and
the best way to understand it is to
experience it for yourself!
