Focusing in on the notion that the people are always "standing" in Moses' presence, Levi Yitzchak turns this moment of administrative problem-solving into an insight into the spiritual quest. He writes,
A person should constantly be moving from one spiritual level to the next, and should not stand in one position, with a static quality [lit: with a single aspect/point of view].Moses was challenged not by the work of sitting all day hearing court cases. It was that a person of his spiritual stature was speaking all day with people who were always "standing in one position" and who didn't seek to move from level to level.
The exhausting challenge for Moses - the reason Yitro tells him a couple of verses later this will wear you out....it is too heavy a task for you - is to spend all day trying to lift the spiritual state of others around him, trying to get them to go from one level to the next.
How often have we in our own lives reached a point of comfortable stasis. Everything is just right but so, so wrong (there's a song about that). We stop growing, stop becoming.
The tzadik (righteous person) Moses is presented here by Levi Yitzchak not as the dispenser of judgments about Jewish law but instead as the great nudge trying to push people to get moving, to leave behind where they are to go to the next level. To live, to grow, to ascend.
Torah tries constantly to move us from one level to the next, to get us to refuse to accept our lives, our identities, our world as "given." It is constantly to be renewed and uplifted.
