I am an 18th Degree Grand Master Reiki Healer working with 18 levels of Yamabushi Shinto Reiki.
I was attuned to these energies by my shamanic teacher who founded them whilst deep in meditation on retreat on Mount Kurama, a sacred mountain with wonderful Shinto shrines, which is also the mountain on which master Usui first brought Reiki through. My teacher was awakened to a much deeper level of Reiki, and was told to pass on this deeper power, as the tradition had become diluted.
The Yamabushi, meaning mountain sleepers, are traditional Shamans of Japan, and are the original spiritual tradition from which the ninjas evolved. My teacher trained from 13 years old in various martial arts. This, alongside the Shinto shrine location, is what inspired the name for this Reiki.
