07/28/2026 | 55 mins.While we await the next installment of the 18Forty Podcast, we invite you to enjoy this episode from our serires 18 Questions, 40 Mystics.Â
In this insightful conversation, Rabbi YY Jacobson presents Jewish mysticism as a dynamic framework for consciousness and connection rather than abstract theology. He passionately and clearly illustrates how faith and, ultimately, surrender can redefine how we see ourselves, our pain, and the world around us.Â
Before the Lubavitcher Rabbi’s passing, Rabbi Jacobson served as one of his oral scribes. As a close disciple of the Rabbi, he developed a strong foundation in the world of Chassidut [Hasidism] and Jewish mysticism. Now, Rabbi Jacobson is a world-renowned speaker and scholar.
He now joins us to answer eighteen questions with Rabbi Dr. Benji Levy on Jewish mysticism including how Torah is the map of reality, how spirituality should inform your relationships, and the function of humility in religious growth.Â
Here are our questions:Â
What is Jewish mysticism?
How were you introduced to Jewish mysticism?
In an ideal world, would all Jews be mystics?
What do you think of when you think of God?
What is the purpose of the Jewish people?
How does prayer work?
What is the goal of Torah study?
Does Jewish mysticism view men and women the same?
Should Judaism be hard or easy?
Why did God create the world?Â
Can humans do something that is against God’s will?
What do you think of when you think about Moshiach?
Is the State of Israel part of the final redemption?
What is the greatest challenge facing the world today?
How has modernity changed Jewish mysticism?
What differentiates Jewish mysticism from the mysticism of other religions?Â
Does one need to be religious to study Jewish mysticism?
Can mysticism be dangerous?
How has Jewish mysticism affected your relationships with yourself and with others?
What is a Jewish teaching that you always take with you?
