Dear Avi: Many thanks for your letter and the enclosures – all of which I read with much interest and delight. My grandfather, o.b.m., who was also my Rebbe, wrote a couple of sefarim. When another author mailed his work to my grandfather, the latter would respond by sending him a copy of his sefer, and inscribe it: chaburah tachat chaburah... In the same spirit, I enclose a number of recent publications, and will have another one sent to you separately. Keep them coming!
