i visited an upcountry forest wat a while back and the temple was inhabited by a single heavyily tatooed monk who amoung other things (food, incenses, smokes, water) on the floor around him was a large jar filled with liquid and what looked like an aborted or stillborn pitbull fetus

any ideas?????

Don't have many ideas on that one.

It could be that someone offered it, and he just leaves it around. I have noticed all kinds of junk lying around temples.

It could also be a tool for reflection on the impermanence fo life.

Or otherwise a refelction on the unattractive view of bodies.... there are many passages that refer to viewing the body as unpleasant - such as the reflection on the 32 parts of the body

.... skin, flesh, bones, marrow, kidneys, membranes.....

This then, which is my body, is a sealed bag of skin filled with unattractive things..

It could also be a tool for reflection on the impermanence fo life.

Ajarn Chah used to keep a human skeleton inside the door of this temple for the same reason. Freaked a lot of people out.
