This ancient practice has been around since before the early twentieth century in Japan. The earliest evidence of Reiki was found in Ancient Egypt and known as Sekhem Energy Healing.
What we identify now as Reiki is credited to a practitioner named Mikao Usui. He said that he had been blessed with the ability to heal without depleting his own energy. He went to Mount Kurama and meditated for three weeks. Afterwards, he went back to his village and began teaching others about this healing technique and the symbols that needed to be used in each treatment.
Usui used initiations called Reiji-ho to enhance people's access to the healing energy. These later became known as attunements. Attunements also gave the student a clearer ability to channel the Reiki as well.
Included in the Reiki teachings were five tenets that give us a simpler way to live our lives. Usui was a reader of the works of Emperor Meiji. In the process of developing his Reiki techniques, Usui borrowed some of Meiji's teachings. These tenets are to be said twice a day at morning and at night. The five tenets are as follows: Just for today I will not worry, Just for today I will not anger, Just for today I will honor all life, Just for today I will earn my living honestly, and Just for today I will give thanks for everything.
Some of Usui's student preferred to actually touch the patient and find out where the trouble spots were. Usui practiced a technique called scanning. He used scanning to find imbalances and closed chakras.
Depending on the level of stress and toxicity in the body a person receiving Reiki may experience chills, fever, headache, crying, negative memories surfacing or a number of other feelings. With regular sessions, the benefits far outweigh these symptoms. A few benefits of receiving Reiki are relieves pain, anxiety, fatigue, treats depression, and boosts mood.
