This unusual biography portrays the life and unbounded spiritual workings of Mario Mantese. People who know him for many years tell of their meetings with Master M and of his extraordinary universal activity. They share accounts of wondrous, astonishing, and mystifying occurrences, which they experienced in his presence. They were deeply touched by the light that emanates from him, and could thus discover unfathomed depths within their own lives. What unfolds for the reader is a glimpse into the limitless, luminous foundation of our world.
