Chuckling in the Bardo is a short fiction. You can take it literally or figuratively. It’s very loosely based on the Bardol Thodol, or Tibetan Book of the Dead, a Buddhist text that describes an intermediate state between life and death in which the narrator faces a number of tests, including strange landscapes, lost souls, peaceful and wrathful deities that determine whether he will achieve enlightenment or be reborn, possibly to a better station, possibly much worse.
The Music is by Sturgill Simpson, from his album Sound and Fury. Ronin and some of Remember to Breathe. If you are unfamiliar with it, you should definitely watch the video he had made with top Japanese anime artists for the album on Netflix. Just search for Sound and Fury, or Sturgill Simpson.
Should anyone come across this questionable use of copyrighted materials, I consider it fair use as this is a private post, not visible to the world, no more than five people will see it, and it won’t be up for long.
