Birkat HaMazonThe word Jew (Yehudie) means to be thankful and the birkat HaMazon is an expression of thanks for the bounty of a meal that ultimately derives from Hashem. In Hilchot Berachot of Rambam;s MT chapter 1 Rambam writes, "It is a positive mitzvah deoreita to bless G-d after eating nourishing food as Deut. 8:10 states, "וְאָכַלְתָּ, וְשָׂבָעְתָּ--וּבֵרַכְתָּ אֶת-יְהוָה אֱלֹהֶיךָ, עַל-הָאָרֶץ הַטֹּבָה אֲשֶׁר נָתַן-לָךְ" Hazal legislated that one should recite grace after meals if one has eaten bread the size of an olive bulk. In Sefer Zohar Midrash Nealam, in addition to the halakhic requirement, "theurgic significance" is illuminated to the act of reciting grace. This mikorot packet includes (1) classical mephorshim, (2) Sifrei Hasidut , and (3) sifrei Machshava (Jewish Thought) (4) and a Bibliography on the importance of being grateful for G-d's gifts and bounty from which we benefit and acknowledge in the birkat HaMazon.
