I understand that the focus here is "Just Sitting".

That is a mental process (or spiritual), is it not? And not a physical one at all? Otherwise a being who was physically incapable of sitting would never be able to practice.

What do you reckon?

I originally discovered this forum after reading about the debacle at e-sangha, but I'm not in the mood for writing about that at the moment. I too was banned for disagreeing with literal rebirth.
