OM has been teaching orally and in writing ever since, accompanying people in their search for truth and self-knowledge at spiritual events (Darshan). In addition, he is the author of a variety of books, writings and articles, including the recent English publications of The Digital Age, The Birth of the Lion – Non-Duality as a Way of Life, and Intelligence of Awakening – Navigating the Wisdom Path.
OM founded the first major German-speaking mystery school of the present time in the '90s. Since 2010, the school is located at Gut Saunstorf, a splendidly restored historic manor house near the Hanseatic city of Wismar, that has been known as the "Ort der Stille" (Place of Stillness). As a modern monastery, it is also open as a retreat for people who are on the inner path.
OM C. Parkin's spiritual teaching, also referred to as Inner Science, is based on the Eastern Advaita tradition (teaching of non-duality--the best-known representative of this tradition in the West is Ramana Maharshi). This teaching also encompasses Western experiential paths (e. g. Christian Mysticism, Georges I. Gurdjieff: The Fourth Way) as well as modern psychological and psychotherapeutic methods. The goal is self-knowledge through inner work, which ultimately leads to the realization of the true human nature. OM is also preparing for an American tour in October of 2020.
