Respen, Reiki I is all of reiki. Reiki II gives the symbol for emotions but this is not a higher frequency. Reiki III has to do with being a professional reiki practitioner which is unnecessary for most people. there is no higher frequescy than reiki I. There is no energy in the Universe higher than reiki I. People try to lure you by promising otherwise but it is you who makes for your experiences of higher frequescy.
What you are after is no blockages in you. As you release your blockages, one by one, you are able to feel more energy which seems like a raise in frequency but isn't.
