Mikao Usui

“Remember, the difficulty with Kundalini awakening is that in traditional methods, the Kundalini is awakened while the sushumna has not yet opened. So, there is no passage for the energy to flow through. An awakened Kundalini has a strong energy that creates pressure if it is blocked and has nowhere to go. That is when the Kundalini energy pushes against different parts of the body and creates problems. However, as already mentioned, in the REIKI attunement, your whole sushumna is opened thoroughly during the first level attunement as preparation for your Kundalini awakening. The second level attunement opens your sushumna even wider. As your Kundalini awakens, the unobstructed energy passage is there, ready to be used by Kundalini energy.”

“A full Reiki treatment reopens the chakras and re-balances the flow of the universal life force around the body. A person will normally need four full treatments on four consecutive days to boost the flow of Reiki energy.”
