If thinking about the mortality of the creatures around you is more painful than thinking about your own, then maybe you do have something to be grateful for
from an abo preservative mortality has never been something to be afraid of. we don't really have afterlife in our religion. we just see everything as temporary, rivers shift, grasses come and go, same with herds of roo. we come, we go. that's it. try to enjoy existing while you exist.
