The Holy Book of the Great Invisible Spirit, also known as the Coptic Gospel of the Egyptians is a Sethian Gnostic text found in Codices III and IV of the Nag Hammadi library. The text describes the origin of three powers: the Father, the Mother, and the Son, who came forth from the great invisible Spirit. The text emphasizes Seth as the origin of the seed of eternal life and the great, incorruptible race. It concludes with a prayer and a statement that it was written by the great Seth and placed in the mountain Charaxio to be revealed at the end of times.
