Reiki self attunement is still quite controversial for some healers. Some healers believe that a healer must receive a reiki attunement from a competent reiki master, while others believe that reiki self attunement is possible. Those who believe that it is possible, believe that Dr. Mikao Usui, who is the founder of reiki, attuned himself during his meditation on Mount Kurama. This is quite logical, since he was all alone at that time.
Reiki master Judith Conroy believes that Dr. Usui went to a quiet place alone, and after a period of fasting and meditating, he experienced a deep understanding about how a universal force already flowing within him. Then after a while, he learned how to accessed the energy and used it for healing purpose.
Those who do not believe this concept, believe that Dr. Usui was attuned by a great light come out of the darkness, hit him in the forehead and gave him reiki. Majority of healers still believe in this concept.
Reiki self attunement made it possible for someone to become a complete reiki master all at one, without any waiting period, and without different levels. Some reiki masters under this concept also offering master course in just 48 hours.
Regardless of which way you are going to take, a conservative reiki class with attunement from a master or self attunement, the most important thing is the energy you are accessing and channeling. Both methods have been proven to be working. One must make sure that he or she is doing meditation and healing in Unconditional Love. Unconditional Love is the energy of the creation. This is the energy that The Source uses to create all existence, including the universe, the earth and all of us. If you practice reiki in Unconditional Love, you can not go wrong. This is very true whether you received an attunement or you have reiki self attunement.
