Smooth Transitions Reiki is a system that I have used on many occasions while treating clients due to its ease of use as the pure divine assistance that is given to me during a healing session. The main function of Smooth Transitions Reiki is of helping the healer to move from one form of healing to the next with ease. Simply put, activating the energies during a healing session will allow you to move from a highly advanced energy function to a more comforting function.
