The world's first Reiki book published in an academic medical publishing house. And the reference work on the Reiki symbols.
The world's first Reiki book published in an academic medical publishing house. Born from decades of practice and research — for Reiki practitioners, physicians, and anyone who wants to understand Reiki at depth. Concrete. Precise. Deep.
The seven secret techniques Mikao Usui developed — to amplify spiritual capacity and refine perception. What began in this book is now directly transmitted in Shingon Reiki 1 and carried far beyond the original scope.
The reference work on the spiritual lineage of the Reiki symbols and mantras of the Usui system — for the first time with original sources from Japanese esoteric Buddhism, calligraphy instruction, and the deep cultural origin of every single symbol. An international bestseller, on the desks of practitioners worldwide.
Mark's doctoral thesis in East Asian Art History at Heidelberg University. The academic foundation of Shingon Reiki: the Siddham script in Japanese art, its use in rituals and meditations of Buddhist healing practice — and how it forms the origin of Mikao Usui's Reiki. Years of field research at Kyoto University and in Buddhist temples, funded by DAAD, Rotary and Seckel.
Japan's shamanic lineages are closely woven with Shingon and Shinto. These books open that connection — for anyone who wants to go deeper than the surface of spiritual practice.
Seven steps into the mystical world of wolf shamanism — with the shamanic context behind Reiki, and a dedicated practice section using Shingon Reiki to release the masks you wear. Practical rituals, meditations and exercises you experience yourself. For anyone who wants to release foreign energies, follow their vision, and understand the connections between Japanese shamanism, Shugendo, Shinto and shamanic Daoism.
The drum as a gateway — between worlds, between lineages. It has carried shamanic ritual for thousands of years. An intuitive practice open to anyone, no prior experience needed — discover musical and spiritual capacity, release emotional entanglements, and re-encounter sensuality, desire and joy of life.
Two books are taking shape right now — both from lived practice, not from the desk.
The first book Mark and Eileen are writing together. Shingon Reiki in its current form — with its Buddhist depth, the spirits, the initiations, and what two decades of practice have brought into clarity. Release date to be announced.
Eileen's first book of her own. Meditation not as a technique, but as a lived path — with Shingon Buddhism as the spiritual ground and embodied practice as the thread running through. Release date to be announced.
Alongside the books, Mark has published regularly in specialist journals — primarily in Reiki Magazin and its special editions, as well as translations from Japanese sources.
Topics covered there:
"For many years I've been a captivated listener to Dr. Mark Hosak's deeply interesting lectures. His book Reiki in der therapeutischen Praxis (Haug Thieme) has been with me ever since."
"I'm so glad I discovered Mark Hosak's The Big Book of Reiki Symbols in a large bookshop in Mainz in 2004. That led me to step into Shingon Reiki Level 1 with Mark in April 2005. Even then I was immediately struck by the clarity and intensity with which Mark held the practitioners on the path."
"I've always been so happy whenever I could be at an event with Dr. Mark Hosak. He takes so much time, explains everything thoroughly. I'd come back any time. His books are also very informative and a great reference. Highly recommended."
