Igeret HaKodesh: Epistle 25 - Part 7

Re: four worlds While the Kabalist point to the verse in Isaiah 43:7 "Everyone that is called by My name, and whom I created for My glory, I formed him, yea I made him.'" as alluding to the four worlds, they aren't actually mentioned in the Torah. Rather, it is from Kabbala and the oral tradition. To learn more about the Four Worlds and the Tzimtzum see The Four Worlds Reply
