Gregorii Nysseni De vita Moysis

"This work has a special significance because it reflects Gregory's spiritual sense of the Scriptures. He maintained that the ultimate purpose of the Bible was not its historical teachings but its capacity for elevating the soul to God. Gregory saw the totality of the spiritual life as an epektasis, a continual growth or straining ahead, as in the words of St. Paul, 'Forgetting the past, I strain for what is still to come.' Describes the spiritual ascent as taking place in three stages, symbolized by the Lord's revelation of Himself to Moses, first in light, then in the cloud and finally in the dark." -- Publisher's description.
