(Note: I asked Claude to create a "slightly humorous" app).  The shortcut: suffering (dukkha) is not the presence of painful emotion like grief, but the mind’s reactivity. It is its clinging, resistance, or identification with that emotion. Through serious meditation specific types, one can create a stable awareness that allows emotions to be fully experienced without becoming overwhelmed or stuck in them. Conceptual acceptance of impermanence is only a starting point.  Deeper transformation comes about through direct meditative training that rewires how the mind processes experience.
