Rev Mario’s spiritual teachings developed from three main sources. The first was the early training within the traditional church. The second was the training he experienced within a European Mystery School; the third was his own developing clairvoyant vision. Mario’s teaching was constructed within a Western framework and contained echos of many sources ranging from classical philosophy to medieval esotericism.
Mario's teaching evolved over almost thirty years. The site "Realm-2" is devoted to an articulation of these teachings.
