Rabbi Wallerstein just started giving a Tuesday shiur to Ohr Yitzchack on Kav Hayashar (which will also include material from Tomer Devorah).
Kav Hayashar is a transformative book and even though I read it once & felt I got a lot out of it, just Rabbi Wallerstein's first shiur on it gave me so much more.
(Kav Yashar is the book Rabbi Wallerstein from which he told the story of the miserly mohel and the demons, connecting it all to addiction.)
So just to reiterate: Rabbi Wallerstein will go through all 102 chapters of the Kav Hayashar every Tuesday until they finish the entire book. It's thrilling.
Here is Rabbi Wallerstein's first shiur on the Kav Hayashar:
