In my weltanschauung   the ethics of the Torah is root of the universe. This idea came about  from learning Musar [Ethics of the Torah], but I saw it later in Shalom Sharabi.
That is at least something I saw in the Alter of Slobadka openly. אור צפון. The Hidden Light. That was one of the writings of the disciples of  Reb Israel Salanter.  I saw this  right smack at the beginning in a very powerful way. I forget how he put it but it was along the lines that the sin of Adam was in character.
