In April 1922, Usui moved to Tokyo and founded the Usui Reiki Ryōhō Gakkai ("" in old style characters, meaning " Usui's Spiritual Energy Therapy Method Society ") in order to continue treating people on a large scale with Reiki.

After Usui's death, Hayashi left the Usui Reiki Ryōhō Gakkai and formed his own clinic where he gave Reiki treatments, taught, and attuned people to Reiki, and it was to this clinic that Hawayo Takata was directed in the 1930s.

* Usui Reiki Ryōhō Gakkai ( 臼井靈氣療法學會 in Traditional Chinese Characters, meaning " Usui Reiki Healing Method Learning Society ") is the name of the society of Reiki masters founded by Mikao Usui.

This system is derived from Usui Reiki as taught by Takata and includes techniques from the Usui Reiki Ryōhō Gakkai, such as Byōsen-hō ( 病専法, Scanning Method ), Gyōshi-hō ( 凝視法, Healing Eyes Method ), and Kenyoku-hō ( 件抑制法, Dry Bathing Method ).

" In 1993, he was granted membership to Usui Reiki Ryōhō Gakkai.

While in the process of developing his Reiki system, Usui summarised some of the emperor's works into a set of ethical principles ( called the " Concepts " 概念 Gainen ), which later became known as the Five Reiki Precepts ( 五戒 Gokai, meaning " The Five Commandments ", from the Buddhist teachings against killing, thievery, sexual misconduct, lying, and intemperance ).

* Kōmyō Reiki Kai ( 光明レイキ會, meaning " Enlightened Spiritual Energy Meeting ( Association )") is the name given to the system that takes the name of a school of Japanese Traditional Reiki, and was established by Hyakuten Inamoto ( 稲本 百天 ), a Reiki teacher with Western Reiki background.

* Jikiden Reiki ( 直傳靈氣, meaning " The Direct Teaching Spiritual Energy ") is the name given to the original system that was taught by Dr. Hayashi, and was founded by Mrs. Yamaguchi and her son, Tadao Yamaguchi ( 山口 忠夫 ).

* Usui Reiki Shiki Ryōhō ( 臼井靈氣式療法, commonly translated as meaning " Usui's Spiritual Energy Style of Therapy ", but a more literal translation is " Usui's Spiritual Energy Style of Medical Treatment " ( Ryōhō ( 療法 ) meaning medical treatment )) is the name given to the Western system of Reiki, and is a system that has tried to stay near enough the same as the original practises of Hawayo Takata.

* Gendai Reiki Hō ( 現代靈氣法, meaning " Modern Spiritual Energy Method ") is a system that incorporates elements of both Japanese and Western Reiki, and was established by Hiroshi Doi.

Further to this notion, the belief is that the energy is " intelligent ", meaning that the Reiki knows where to heal, even if a practitioner's hands are not present in the specific area.

The first degree Reiki course, sometimes given the Japanese name of Shoden (" 初伝 " in Japanese, meaning " Elementary / Entry Teachings "), teaches the basic theories and procedures.

In the second degree Reiki course, sometimes given the Japanese name of Okuden (" 奥伝 " in Japanese, meaning " Inner Teachings "), the student learns the use of a number of symbols that are said to enhance the strength and distance over which Reiki can be exerted.

Through the third degree, or " master training ", sometimes given the Japanese name of Shinpiden (" 神秘伝 " in Japanese, meaning " Mystery Teachings "), the student becomes a Reiki Master.

Gasshō (" 合掌 " in Japanese, meaning " two hands coming together ") is a meditative state where both palms of the hands are placed together, and was practised each time at the beginning of Usui's Reiki workshops and meetings.

" The American Cancer Society and the National Center for Complementary and Alternative Medicine have also found that there is no clinical or scientific evidence supporting claims that Reiki is effective in the treatment of any illness.

Ningizzida has been popularised in the 20th C. by Raku Kei Reiki ( a. k. a. " The Way of the Fire Dragon ") where " Nin Giz Zida " is believed to be a fire serpent of Tibetan rather than Sumerian origin.

Reiji-hō ( 霊示法, meaning " indication of the Reiki power method ") is a means of connecting with the Reiki power by asking it to flow through the practitioner three times, and is commonly split into three parts.

Though differences can be wide and varied between both branches and traditions, the primary difference is that Westernised forms use systematised hand-placements rather than relying on an intuitive sense of hand-positions ( see below ), which is commonly used by Japanese Reiki branches.

The concept of ki underlying Reiki is speculative and there is no scientific evidence that it exists ; a 2008 systematic review of randomised clinical trials concluded that " the evidence is insufficient to suggest that reiki is an effective treatment for any condition.

Reiki is commonly written as 霊気 in shinjitai kanji or as レイキ in katakana syllabary.

It is claimed that by a mystical revelation, Usui had gained the knowledge and spiritual power to apply and attune others to what he called Reiki, which entered his body through his crown Chakra.

It is common for many Reiki teachers and practitioners to abide by these five precepts, or principles.

The term Traditional Japanese Reiki is normally used to describe the specific system that formed from Usui's original teachings and the teachings that did not leave Japan.

Western Reiki ( 西洋レイキ, Seiyō reiki ) is a system that can be accredited to Hawayo Takata.

" This style of Reiki places more emphasis on the healing of ailments, and ascension to higher levels of attunement is more formalised.

* Usui / Tibetan Reiki is the name given to the system that was developed by Arthur Robertson and later popularised by William Lee Rand and Diane Stein.

Traditional Japanese Reiki was taught intensively under Usui's guidance, with weekly meditation meetings where Reiki was given and used to scan the body in order to supply an energetic diagnosis, which is known in Japanese as Byosen-hō, as a Japanese Reiki treatment is intuitive and specifically directed in comparison to a Western Reiki treatment, which tends to generally treat the whole body instead of specific areas.

Another attunement is given, which is said to further increase the capacity for Reiki to flow through the student, as well as empowering the use of the symbols.

After Reiki had been given first to the head and neck area, specific areas of the body where imbalances were present would then be treated.

The system of Reiki was developed by Mikao Usui ( 臼井甕男 ) in 1922 whilst performing Isyu Guo, a twenty-one day Buddhist training course held on Mount Kurama.

According to the inscription on his memorial stone, Usui taught his system of Reiki to over 2000 people during his lifetime, and sixteen of these students continued their training to reach the Shinpiden level, a level equivalent to the Western third, or Master / Teacher, degree.

As a result of the second world war, Takata decided to modify the Traditional Japanese Reiki system in order to make it more understandable and credible to the mentality of the West.

In this system, as with most Western systems of Reiki, there are three levels, respectively called the First Degree, Second Degree, and Master / Teacher Degree, which uses Takata's versions of the four original symbols passed to her by Hayashi.

Along with the five Reiki principles, Usui based his Reiki system on three other practises ; Gasshō, Reiji-hō, and Chiryō.

After multiple Reiki sessions from Hayashi's trainees at his clinic for illnesses including abdominal pain and asthma, Hayashi initiated and trained Takata to use Reiki, and she became a Reiki Master on 21 February 1938.

The duration of the master training can be anything from a day to a year or more, depending on the school and philosophy of the Reiki Master giving the training.

Clinical trials have not reported any significant adverse effects from the use of Reiki.

Hoping to avoid surgery in a bid to not delay his pending projects, and based on his former experience with a failed knee surgery three years earlier, Khan tried multiple alternative therapies from homoeopathy to Reiki but nothing offered a permanent solution.

Takata died on 11 December 1980, by which time she had trained 22 Reiki masters, and almost all Reiki taught outside Japan can be attributed to her work.

Usui Reiki Ryōhō.

Usui Reiki Ryōhō.

The Japanese Reiki hand positions presented in the Usui Reiki Ryōhō Hikkei ( 臼井靈氣療法必携, Usui Reiki Treatment Handbook ) as used and compiled by Usui are considerably more extensive than the hand positions used in Western Reiki.

Usui Reiki Shiki Ryōhō is also the norm requested qualification ( along with Reiki lineage ) when seeking insurance to practise Reiki on the general public in the United Kingdom.

Unlike Usui Reiki Shiki Ryōhō, it has four levels, commonly called First Degree, Second Degree, Advanced Reiki Training ( commonly 3A or ART ), and Master / Teacher ( commonly 3B ).
