I am having doubts about using reiki for psychic protection and have read that some Buddhist teachers do not allow the practice of reiki during retreats. Furthermore, some Buddhist teachers have told students to never practice it again after sitting in a Vipassana retreat.
I will blog more about this when I can decide how I feel about it. Google reiki controversies to see the other side to this energy concept. I myself experienced a very bad energy when the monk prayed a sacred prayer over me in the presence of the reiki book I presented to him. He did not touch it nor did he ask to see it and I feel the monks are holy men guided to holy safe practices.
We must all make our own decisions.
I believe reiki is a psychic trap designed to keep us from focusing on enlightenment and the truth.
Please avoid it.
