The text proclaims that Jesus remained on earth after the resurrection for 11 years, and was able in this time to teach his disciples up to the first (i.e. beginner) level of the mystery. It starts with an allegory paralleling the death and resurrection of Jesus, and describing the descent and ascent of the soul. After that it proceeds to describe important figures within the gnostic cosmology, and then finally lists 32 carnal desires to overcome before salvation is possible, overcoming all 32 constituting salvation.
The female divinity of gnosticism is Sophia, a being with many aspects and names. She is sometimes identified with the Holy Spirit itself but, according to her various capacities, is also the Universal Mother, the Mother of the Living or Resplendent Mother, the Power on High, She-of-the-left-hand (as opposed to Christ, understood as her husband and he of the Right Hand), as the Luxurious One, the Womb, the Virgin, the Wife of the Male, the Revealer of Perfect Mysteries, the Holy Dove of the Spirit, the Heavenly Mother, the Wandering One, or Elena (that is, Selene, the Moon). She was envisaged as the Psyche of the world and the female aspect of Logos.
