The constant need for instability and regrowth, the natural process of development as we go through numerous cycles of small galuyot, exiles and ge'ulot, redemptions, and the complete breakdown of this process in the world we live in

A concept that is not sufficiently appreciated in general, and specifically not appreciated in the context of Existence and Torah, is the need for the world to develop in messy stages, going through numerous cycles of stages of primitive stability to messy instability, and back to a more advanced stage of stability, only to then break down again and repeat itself. And no stage can ever be skipped because the world cannot feign being in a more advanced state than it is. A lot of the problems that Klal Yisrael go through in their history, many of which around God's burning fury, are the necessary stages in a long, painful adolescence, as it were, as the nation is slowly and messily coming into its own.
