"And when she saw her desire, it changed into a form of a lion-faced serpent. And its eyes were like lightning fires which flash. She cast it away from her, outside that place, that no one of the immortal ones might see it, for she had created it in ignorance. And she surrounded it with a luminous cloud, and she placed a throne in the middle of the cloud that no one might see it except the holy Spirit who is called the mother of the living. And she called his name Yaltabaoth. [...] And when the light had mixed with the darkness, it caused the darkness to shine. And when the darkness had mixed with the light, it darkened the light and it became neither light nor dark, but it became dim. [...] Now the archon who is weak has three names. The first name is Yaltabaoth, the second is Saklas, and the third is Samael. And he is impious in his arrogance which is in him. For he said, 'I am God and there is no other God beside me,' for he is ignorant of his strength, the place from which he had come."
- The Apocryphon of John
In Gnostic lore the entity known as the demiurge is often depicted as a mistake, an aberration willed into existence by the momentary imaginings of the mother goddess Sophia. In the legends he has many names, but the one that concerns us here is Samael. The name literally means the 'blind god', and the themes of blindness and sight run through much of the Gnostic lore, as well as mysticism in general. What does it mean for mankind to be sighted, and indeed what does it mean for a god to be without sight? Samael is often depicted as a seducer and destroyer. In Christianity Samael is often an angel conflated with Satan, and shares certain resonances with the popular depictions of Milton's Lucifer from Paradise Lost. Remember that in Christian theology Lucifer was a title meaning 'Lightbringer', and not technically a name.
Just who or what is designing and engineering our realities?
So what does it really mean to be sighted or blind in a Gnostic spiritual context? I would offer my own belief that to be sighted is to have full or at least partial access to the transformative power of the imagination, as well as access to the knowledge of who and what we really are. I believe that humankind is a race of powerful Vessels - originally designed by Sophia herself to be carriers and reliquaries of the Innermost Light; the power of the infinite in its purest form.
