 Self-knowledge is the beginning of wisdom, this is the beginning of wisdom in all wisdom traditions is to start with knowledge of oneself. Abu Hassan Ash-Shadili, Rahimullah, another great ethicist of our tradition, he says, Ifa aradullahu hawana abdin, when Allah wants the servant to be humiliated, satara anhu uyubahu, he veils the servant from his own faults, and the person in their psyche they're like, I'm fine, there's no problem here. This is a sign that Allah wants to lower the servant, hawan, Allah wants the hawan of that servant. And then he says, Rahimullah wa idha aradullahu aizahu, but when Allah wants the servant to try to be like a supreme, great one, an eminent person, what's called a master, basarahubiha, then Allah shows the person his faults, Allah lets the person see their faults, liyatuba so that they can make tawbah from them, so they can change tawbahs to just let go of them. So again, it presupposes introspection.
