What is Reiki?
Reiki is a Japanese system of energy healing in which a practitioner places their hands lightly on or above a recipient’s body to facilitate the flow of what proponents describe as universal life force energy. The practice rests on the premise that this energy—called ki in Japanese, qi in Chinese, or prana in Sanskrit—can become blocked or depleted, and that channeling it through intentional touch can support the body’s innate healing capacity. Reiki is non-diagnostic, non-manipulative, and typically practiced in a quiet, meditative setting. Unlike massage or bodywork systems that engage muscles and fascia, Reiki involves minimal physical pressure and claims to work on subtle or energetic layers of the body.
Origins & Lineage
Reiki was founded by Mikao Usui (1865–1926), a Japanese Buddhist layman, following a profound spiritual experience on Mount Kurama near Kyoto in March 1922. According to oral tradition preserved by the Usui Reiki Ryōhō Gakkai (Usui Reiki Healing Society), Usui underwent a 21-day meditation and fasting retreat during which he received an intuitive understanding of healing energy and a set of symbols and hand positions. He began teaching his method in Tokyo in April 1922, calling it Usui Reiki Ryōhō (Usui Spiritual Energy Healing Method).
Usui trained approximately 2,000 students and initiated 16 to the teacher level before his death in 1926. Among them was Chūjirō Hayashi (1880–1940), a retired naval officer who systematized the hand positions and opened a Reiki clinic in Tokyo. Hayashi trained Hawayo Takata (1900–1980), a Japanese-American woman from Hawaii who received treatment at his clinic in 1935. Takata brought Reiki to the West, teaching extensively in North America from the 1970s until her death. She initiated 22 Reiki Masters, and the practice subsequently diversified into multiple branches and lineages, including Usui Shiki Ryōhō, Karuna Reiki, and various eclectic Western adaptations.
The Usui Reiki Ryōhō Gakkai continues to operate in Japan, though it remains a private organization with little public engagement. Western Reiki evolved separately, and debates persist about which lineages most faithfully preserve Usui’s original teachings.
How It’s Practiced
A typical Reiki session lasts 60 to 90 minutes. The recipient lies fully clothed on a massage table or sits in a chair. The practitioner places their hands in a sequence of standardized positions—on the head, torso, back, and sometimes limbs—holding each position for several minutes. Some practitioners hover their hands slightly above the body rather than making direct contact. The environment is usually quiet, occasionally accompanied by soft music or the sound of singing bowls.
Practitioners report sensations of warmth, tingling, or pulsing in their hands; recipients commonly describe feelings of relaxation, warmth, or subtle energy movement, though others feel little or nothing. No manipulation, pressure, or diagnosis occurs. Reiki is considered a complementary practice and is not presented as a substitute for medical care.
Reiki training is organized into levels or degrees. First Degree (Shoden) focuses on self-treatment and in-person sessions. Second Degree (Okuden) introduces three symbols used to focus intention and work at a distance. Third Degree or Master level (Shinpiden) includes the Master symbol and, in some lineages, the authorization to teach and attune others. “Attunement” or “initiation” ceremonies, conducted by a Reiki Master, are said to open or activate the student’s capacity to channel Reiki energy.
Reiki Today
Reiki is widely integrated into holistic wellness centers, spas, hospices, and hospitals as a complementary therapy. It is often offered alongside massage, acupuncture, counseling, and palliative care. Some nurses and social workers incorporate Reiki into patient support. Retreats, online courses, and certification programs proliferate globally, though no single governing body regulates Reiki practice or training standards.
Research on Reiki’s efficacy is mixed. Some small studies suggest modest benefits for anxiety, pain, and relaxation, often attributed to placebo effects, the therapeutic value of touch, or the calming environment. Systematic reviews and meta-analyses consistently find insufficient high-quality evidence to support Reiki as an effective medical treatment. The practice is generally considered safe when used as a complement to, not a replacement for, evidence-based medicine.
Common Misconceptions
Reiki is not a religion, though it incorporates ethical precepts (the Five Reiki Principles) and emerged from Usui’s Buddhist practice. It does not require belief to “work,” according to practitioners, though skepticism about its mechanism is widespread in the scientific community.
Reiki is not massage, acupuncture, or physical manipulation. It does not claim to diagnose or cure disease, and ethical practitioners refer clients to physicians for medical concerns. The notion that Reiki can replace conventional medical treatment is both inaccurate and potentially dangerous.
The term “energy” in Reiki is metaphysical, not synonymous with electromagnetic or biochemical energy measured by physics or biology. No scientific instrument has detected the ki that Reiki practitioners describe. The practice is better understood as a meditative, intention-based ritual than as a bioenergetic intervention in the scientific sense.
How to Begin
For those curious about receiving Reiki, seek a practitioner through holistic health centers, massage clinics, or hospitals offering integrative care. Ask about their training lineage, number of hours studied, and whether they belong to a professional association such as the International Association of Reiki Professionals or the Reiki Membership Association.
To learn Reiki, attend a First Degree course taught by a certified Reiki Master. These typically span two days and include history, hand positions, self-care techniques, and an attunement ceremony. Notable introductory texts include The Reiki Sourcebook by Bronwen and Frans Stiene, which provides historical context and cross-lineage perspectives, and Essential Reiki by Diane Stein, a widely read though sometimes controversial manual. Training quality varies significantly; inquire about lineage, curriculum structure, and post-course mentorship before enrolling.
