I was attuned by Rand and learned the symbols from him. We were taught that the symbols were like keys to a lock. I wondered about this. All things carry their own vibration....and thoughts are things. If the symbols are a vibration meant to open another vibration, why not go directly to that vibraton?
My husband and I conducted many experiments with the help of our energy seeing granddaughter. Short stuff had told us about the colors of the symbols. I pulled up a web site which had many symbols from assorted Reiki "schools". She pointed out to me that many were the same color. The kid asked me why I used the symbols when I already send the energy in the different colors?
It is my understanding that the symbols give a visual focus for those unacustommed to energy work and working with intent.
As for strenghtening Reiki, I agree with finality. We have to make our selves a better conduit.
