I have just recently done another Crystal Reiki Session with a Client, she made a point of calling me back to say she felt wonderful, that is so nice to hear feedback!
Reading for Clients has been the most interesting and fun, I like to ask my Guides to tell me something thats just everyday, that has just happened or will, so that the Client can have validation on all of the Reading.
i.e. just bought a pair of shoes, going to meet someone with name of Jeff! just mundane things, that make us laugh!
