If "Mussar" is the noun, what's the verb? (Shema as deep listening and loving) ❦ Conversation #2

Every word in Hebrew comes from a verb, so what's the action word behind Mussar? Oh wait a minute, that action word actually means at least five things, you say? And Mussar is basically a practice of doing those things for myself? What about the first time that action word is used in the Torah, how is that about practicing deep listening and pausing when things start going wrong to ask myself something? And how is Mussar connected to the ancient "Shema" prayer? Can it really help me enter into that beautiful circle of coming to know and love the human and divine Other?
