A blog post I read recently began “In its original form, within Japanese Buddhist circles in the late 19th Century, Reiki was a path to enlightenment”. (End of quote). The remainder of the post focused on the healing practice.
Not only “was a path to enlightenment”, but still is, in the western form and practice. More than that, one does not need to become more “Japanese” or to adopt Buddhism or its philosopy.
There is absolutely no harm, and a certain satisfaction, in immersing oneself in the Japanese language and culture, or developing an understanding of Buddhist thought and meditative practices. But “the way” is not these things.
The risk is as it has always been, of too much mind, Japanese mind, Buddhist mind, right mind, and more.
The “way” of Reiki can be found in the everyday hands-on practice, and the here and the now.
Note “everyday” and “here and now”.
