In this chaburah on Derashos haRan derashah #1, we see the Ran’s depiction of the six days of creation as progress — both in being ever-more-perfect by being compounds of more refined ingredients, and in being necessary to reach next step. Until you reach the human, compound of heaven and earth.
Derashos haRan is an explanation of the fundamentals of the Torah as explicated from texts in the Chumash. The first derashah explains the beginning of Breishis — from Creation through the change in humankind that came with the expulsion from Gan Eden.
