Invented Sanskrit Word of the Day: layasana - the resting, dissolving pose
I propose
layasana as a replacement for
savasana or
shavasana. There is no getting around what
sava is - śava, mn. (ifc. f(ā). ; prob. fr. √1. śū , or śvi and orig. = " swollen ") a corpse , dead body. Sure the ancient yogis meditated in graveyards and went around coated in the cremation ashes of the dead. But that is clearly Vampire Chic. I’m not into it.
Consider the great Sanskrit word laya.
- rest, repose
- place of rest, residence , house , dwelling W.
- [mental inactivity, spiritual indifference
- sport, diversion, merriness
- delight in anything
- an embrace

layasana is less obnoxious than savasana, plus it has the obvious pun in it.
