If you have a connection with any form of guide (animal, human,angel or what ever) that assists your intuition or improvement with reiki, that need to be one thing to cherish and not dismiss. It does not matter about the name and I do not feel it really is categorically fair to say “Reiki guides do not exist.” They clearly do for some individuals.
Saying they do not is extremely rigid, as you then deny individuals who do think in them, their belief. Reiki is not rigid, is open for “any way of belief or pondering” and that need to incorporate people’s connection with guides, I think. If a person has connected with any type of guide that assists them with Reiki, even if its to support with very simple stuff like self self-confidence and trusting one’s personal capacity, it does not truly matter if you get in touch with them a Reiki Guide.
