In college, I had this idea that I would write a series of poems inspired by imaginary tarot cards with suits like "serpents" and "fire" etc rather than rods, cups, coins, swords. I only really ever wrote one of those, and I'm not sure where to find the text of that poem, nowadays. However, that one piece was inspired by a story of the Buddha, in which he sits to meditate in a meadow, and while his mind is a perfect blank, wicked spirits menace him. The world serpent rears up and protects him within its coils.
