Welcome back to a summer series discussing the “four worlds” of Atzilus, Beriyah, Yetzirah, and Asiyah! In this episode, we discuss an essential premise to the concept of “worlds”: what exactly is a world? And what insight can we glean from the names of the four worlds, to help us understand what gives each of them a special standing? [The series is centered on a letter of the Frierdiker Rebbe (found in his Igros Kodesh 4:156 (letter 954), and published with a translation entitled “The Four Worlds” by Kehos in their Chasidic Heritage Series).]
