The point of Rav Nahman of Breslov and the point of those learning his books is to address crises [plural] in an individual's life. It is not to define Torah. Nor is it actually to "be mehazek" strengthen one in keeping Torah-- though sometimes that is the effect. The cause of this is that something changed in human mentality in the 1700's. The old forms of community were still in place, but something about the modern mind changed. The issues and problems became very different.
This is very different from the sort of Musar (Ethics) books of the Middle Ages which were to define what it is that Torah requires from you in terms of Fear of God and character traits. They in essence explain what the Torah is all about in a practical sense. They are slightly different from books of the Middle Ages which deal more directly with the actual worldview of Torah.
What were some of the crises that Rav Nahman was dealing with? The average layman could accept the idea that we ought to just learn and keep Torah plainly and simply. But the problem was with religious leaders that seemed intent on fouling up the whole thing--and still are. So he deals with that often in e.g. LeM vol. I ch.s 8, 12, 28, 60, vol. II ch.s 1, 8 and many other places I forget off hand.
