[Viliam1234]

I am not an expert, but some sources on meditation describe states of extreme emotion, as intermediate steps towards enlightenment. In Wikipedia, the first and second jhana are described as "rapture and non-sensual pleasure" (with or without internal speech respectively). So the proper path to balance seems to lead through mastery of the emotions, not suppressing them.

I think the idea is that you are not your emotions, and you don't have to be ruled by your emotions, but rather the emotions are something that happens to you, and something you can control. Doesn't mean you have to turn them off, it just means you have the option to do so if necessary. Or perhaps you feel the emotion, but are not compelled to act on it.
