Mikao Usui.
The real story.

For a long time, legends circulated about Mikao Usui that have little to do with the Japanese sources. The truth is more interesting. He was a samurai descendant, a martial artist, a seeker — and his path ran through the deepest esoteric traditions of Japan.

No gentle healer.
A warrior on the path.

Mikao Usui (1865–1926) is the founder of Reiki. He was born into a family with samurai lineage, trained in the martial arts, traveled through Japan, China and Europe, and immersed himself in the esoteric traditions of his homeland — Shingon Buddhism, Tendai Buddhism, Shugendo and shamanic Daoism.

His decisive experience came in the Kurama mountains, north of Kyoto. After 21 days of intense practice — fasting, meditation, water purification — he experienced a deep opening of consciousness. What he received there became the foundation of Reiki. Not as a soft relaxation method. As a path of spiritual development and the unfolding of supernatural abilities.

The memorial stone at Saihoji Temple in Tokyo, erected by his disciples, is the only contemporary source about his life. It tells a different story than the later legend. A story of discipline, depth, and an uncompromising search for what is real.

In Shingon Reiki, Usui's original intention is at the center, the way his memorial stone describes it: a path of inner and outer fullness, of growth and of strength.

Individual experience. Every voice is a personal account. Results vary and depend on prior practice, openness, life circumstances, and many other factors. Reiki and spiritual practice are not a replacement for medical or psychological treatment.

“I am very glad I came across Mark Hosak's book. After that I decided to receive the initiation into Reiki Level 1 with Mark Hosak in April 2005. Already back then I was deeply impressed by the clarity and the intensity with which Mark guided the practitioners on their path."

“I've been on the path with you for five years now, dear Mark. It took me a little while to decide. First I experienced Reiki, then something shamanic, and finally a monk weekend."
