And God said to Abram, “Go out from your land, from your birthplace, and from your father’s house, to the land that I will show you.” (Genesis 12:1) “I will make your nature known in the world” (Rashi). I heard from my Master in the name of Rav Sa’adiah Gaon, that a person is created solely to break his negative, inborn character traits. Through this, he raises up the level called “your nature” [i.e. what is natural for you] “in the world” - [i.e. into the world] Above.” It is called “world” (olam) from the word “hidden” (he’elam) and “concealed.” Kesser Shem Tov, p. 3b
