The Chazon Ish pointed out in his small Musar book the importance of being strict in halacha. But what happens when there are conflicts in how to keep the strict law? Then you need an awareness of the order of importance of the laws. In this learned from Musar books the importance of midot tovot.in particular the Duties of the Hearts is found help to see what aspects of Torah to emphasize.
Without Musar it is very easy to lose sight of what is important in Torah law. So the aspects of Torah that i think are the most important are monotheism and good midot--''to be a mensch''
[This came up yesterday when I heard one girl is disparaging fanaticism. I did not interject my own two cents at the time, but afterward I mentioned that you have to be fanatic about being in the middle--to seek the middle ground between faith and reason. And in terms of Torah law that means not to add nor subtract. כל המוסיף גורע --ALL that add, end up subtracting.]
