Welcome to a summer series discussing the “four worlds” of Atzilus, Beriyah, Yetzirah, and Asiyah! In this episode, we continue to discuss the world of Atzilus, turning the focus to the idea of how Atzilus related to the reality that exists beneath it, and how it toes the line between existence and a lack of existence. 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).
