Do Arahants experience non-neutral mental vedana?

I think so. They just don’t “pick up” (to borrow an Ajahn Chah phrase) any thoughts connected with the unwholesome that might happen to arise in their mind, as the Buddha explained in the two kinds of thinking sutta. Whatever painful or pleasant thoughts might arise, they don’t give rise to aversion or grasping… they don’t enter the “heart” or “proliferate.” That shaking, wobbling, tremoring which the ordinary mind does when confronted with something frightening, exciting, etc: that kind of mental reaction doesn’t happen anymore. Their mind is “unshakeable.”

Hope that helps, and I look forward to hearing everyone else’s take :smile:
