To know that, one first needs to know--or at least to get a glimpse of--the Gadol Hador himself.
In Brachah V'hatzlachah, you will experience what it was like to be in the close proximity of Maran Sar HaTorah, Rav Chaim Kanievsky ztvk"l, on a daily basis. Like the proverbial "fly on the wall," you will be able to listen in to the questions that were posed to him, and hear the amazing responses that he offered--often in only a word or two.

You will follow Rav Chaim on his awe-inspiring daily schedule; you'll get a taste of his remarkable "chovos" (the learning regimen that enabled him to finish kol haTorah kulah each and every year); you will witness the miracles that seemed to be commonplace in Rav Chaim's presence. Most of all, you will get a glimpse of greatness that is hard to imagine--that is, until you read about it firsthand, straight from the pen of Rav Gedaliah Honigsberg shlit"a, Rav Chaim's grandson and trusted gabbai for decades, who actually was witness himself to all of the interactions and vignettes recorded in this book (originally Minchas Todah in Hebrew).
Read, and be amazed! Read, and become inspired! Read, and receive chizuk from the gadol who, from his small corner on Rechov Rashbam, cared about each and every Yid and blessed them all with brachah v"hatzlachah.
