Rabbi Kirzner (ztz”l) was one of a kind individual that has the ability to awake the heart. You can purchase his MP3 shiurim at the following site: http://www.rabbikirzner.org. I recommend his Chumash Bible Series as well as Relationship & Why the Innocent Suffer series. Every shiur will move you.
Ksiva V’Chasima Tova To All!
