Reiki - More Concerning the Symbols

EXCERPT:

Some time ago I remember reading an interview in one of the Reiki magazines in which either Phyllis Furumoto, or Paul Mitchell (- her co-holder of the Office of Grandmaster in the Reiki Alliance) stated that there are actually only three Reiki symbols used in Usui Shiki Ryoho ( - meaning this in the sense of: 'in terms of giving Reiki treatment'). [We know Takata-sensei taught the sole use of DKM was for attunement.]
It was only a short while after this (-and some might say it was merely a coincidence?) that Hiroshi Doi decided to reveal yet another new snippet of 'secret Gakkai information', i.e: that there were actually only three symbols in the Usui Reiki Ryoho system...
However, unlike the Reiki Alliance leaders, Doi's meaning was not that the DKM was solely reserved for attunement purposes. He was claiming that there were only three symbols. Period. Three symbols - and the DKM was not one of them!
