In memory of my Teacher Rabbi Aharon Walkin Zatzal. Although I spent very little time with him compared to others his impact towards me was very great. When I started with him in 2000-2002 I had asked if I can buy his audio tapes to learn on my own. Who would know that these lost tapes of Shiurim will be so priceless and valuable. If you enjoyed this please send all support to his family thank you may G-d Bless!.
