The people behind Shingon Reiki

Not from books.
From lived experience.

Shingon Reiki comes from a direct lineage — master to practitioner, initiation to initiation, from Japan into the world. These are the people who carry it forward.

Academic depth meets lived practice —
and means it.

Some people write about spirituality. Others live it. Mark does both — and refuses to separate the two.

As a teenager he sensed something he could not explain — a connection to something invisible, but completely real. He never let it go. It carried him into Japanese Studies, into a doctorate, to Kyoto — and finally into the temples, not as a tourist, but as a practitioner.

Three years inside the temples of Kyoto. Not as an observer. As someone who practiced there, who received and was received — by monks who still live the tradition today.

The Shikoku Pilgrimage with all 88 temples is not a tourist's accomplishment. It is an initiation into yourself — physical, spiritual, irreversible. Mark has walked it.

As Ninjutsu successor to Taguchi Sensei he carries a lineage that is not passed on through books, but from master to practitioner. His master-level calligraphy was trained under a Zen monk — not as a hobby, but as a spiritual discipline.

Shingon Reiki grew out of this depth — as a fusion of Buddhist initiation tradition and Reiki that exists in this form nowhere else. Not developed at a desk. Born of decades of lived practice.

Add to this his work with shamanic and animist traditions that find their counterpart in Japanese Shinto. And Kuji Kiri — inseparably linked with Reiki inside Shingon — opening the door for those who, behind what they once felt watching anime, are looking for the actual tradition.

Scholarship and magic —
as if they were the same thing.

Eileen grew up convinced that what can be felt is real — even when it cannot be explained. Historical scholarship did not teach her the opposite. It gave her the tools to look deeper.

As a historian focused on religious history, she sees what others overlook: the connections between traditions, the patterns running through cultures and centuries, the actual thing behind what was passed down.

Years of dedicated Qigong and meditation practice — not as a relaxation technique, but as a daily reckoning with what is actually real.

Eileen's path to Shingon Reiki was no accident. She brings the depth that arises when academic thinking and real spiritual practice come together — and when you are willing to take both seriously.

She works especially closely with highly sensitive people — people who perceive a lot, often too much, and who are looking for an anchor. Shingon Reiki gives them exactly that: strength, clarity, and the experience that what they sense is real and makes sense.

Together with Mark she is writing the new Shingon Reiki book — and her own book on meditation with a strong Shingon focus. Neither is being written at a desk. Both come from practice.

Mark & Eileen together

Two paths — one tradition.

Mark and Eileen carry Shingon Reiki forward together — each with their own depth, their own gifts, their own way of accompanying people. Mark brings the historical and academic depth, the direct connection to the Japanese source. Eileen brings the embodied practice, the attuned guidance, the instinct for what people actually need.

Together they are writing the new Shingon Reiki book — and they are gradually moving more of their work to Japan, closer to the source of the tradition.

Voices from the practice

Fellow travelers —
on Mark as a person and initiator.

Individual experience. Every voice is a personal account. Results vary and depend on prior experience, openness, circumstances, and many other factors. Reiki and spiritual practice do not replace medical or psychological care.

"Mark Hosak's Shingon Reiki Institute is top tier. Deeply experienced, deeply knowledgeable, a wise companion."

Thomas S.
Fellow traveler

"I am walking my path with Dr. Mark Hosak too, and I can only recommend him. Dr. Mark Hosak was initiated into all three Reiki lineages, has been working with Reiki since 1992/93, and developed his Shingon Reiki style in 2005 — which he still transmits today."

Raphael A.
Fellow traveler · honoring the research lineage

"By now the Shingon Institute is one of the very few places in the spiritual scene I still go to. What interests me most are Buddhist methods — and this is exactly where I find depth and authenticity."

Sascha U.
Long-time fellow traveler · critical eye

"I attended my first weekend with Mark Hosak back in 2005, after searching online for Reiki weekends. Until 2010 I joined him again and again on weekends — and from the start I was struck by the depth and clarity."
