Corpse Pose, also sometimes called Final Relaxation Pose (yoga)
Its Sanskrit name, “Savasana” (shah-VAHS-uh-nuh), comes from two words. The first is “Sava” (meaning “corpse”), and the second is “asana” (meaning “pose”). (https://m.yogaoutlet.com/guides/how-to-do-corpse-pose-in-yoga)
"The anthropologists are studying two things: how the Texas sun turns a body into a rusted mummy feeding switchgrass, and how vultures scavenge those bodies. To learn about the former, the donated cadavers are laid under metal mesh cages. To understand the latter, they are left exposed, tagged wrists crossed, or open, as in savasana — the corpse pose."
