I would say that feeling anger is a manifestation of kaas. Of course, not letting it out is a good thing, and helps to abate it.
I should mention here that I don’t really think bad middos exist today. I think it is really all emotional issues.
Ex. Nobody has gaava. To have gaava, you first need a health self esteem. Everyone who I know who manifests gaava has a terrible self esteem, and is just manifesting that.
