Most Reiki that is practiced throughout the world is based on that taught and delivered by Dr Usui, which came from Japan.a
Angelic Reiki has a different basis, but is just as effective and helpful.
Trisha is an Angelic Reiki Practitioner, and she is able to provide that service, as well as having her own practical qualifications in Usui Reiki.
You have a choice.
Why not try both and see which works best for you?
