Listen, O soul, to my advice.
Do not become a den for foxes and snakes,
nor a hole for serpents and asps,
nor a lair for lions,
nor a shelter for vipers.
When these things happen to you,
O soul, what will you do?
For these are the Powers of the Adversary.
You were a temple.
You made yourself a tomb.
Stop being a tomb, and become a temple again,
so that uprightness and divinity may remain in you.
Light the light within you.
Do not put it out.
(from the Teachings of Silvanus, a Gnostic Christian text in the Nag Hammadi Libary)
