So negative emotions appearance is a wisdom. One of five!

This makes no sense, so the angriest and most depressed people in the world are the wisest?

Negative emotion arises due to past causes and conditions, there's nothing we can do about that except to avoid the causes and conditions that gave rise to them and so lessen the possibility they will continue to arise in future.

In the meantime while experiencing the negative emotion that has already arisen how one reacts to is where the rubber hits the road as far as wisdom is concerned. Instead of adding to it through increased reactivity and making it snowball observing it with clarity and equanimity understanding it's impermanent, unsatisfactory, and not self nature leads to it running out of steam. This is wisdom.
