The Christian Mystery by Rodney Collin. From the intro:
“And God created man in his own image. In his own image created he also nebula, sun, earth, cell and molecule. For his image is a creature with seven natures, living on three foods, and endowed with all possibilities. Such a creature is truly a cosmos.”
The Christian Mystery by Rodney Collin is indeed visionary and is not meant to be easily accessible. It consists of a series of meditations and reflections on Christian esotericism and Christian Litany for the Enneagram.
