Chasidut do Przysłów 10:6

“Blessings upon the head of a righteous man” (Proverbs 10:6). This is why the Talmud begins with Tractate Blessings (Berakhot), for it is the essence of everything: “Know the god of your father” (Chronicles I 28:9), and afterwards, “serve him,” for you have to know for whom you are serving. This is why a person says a blessing before each ritual act, to dedicate all of his actions to God, as the verse says, “In all your ways, know him” (Proverbs 3:6), as Maimonides wrote. This is accomplished by making the blessing, as the rabbis said the requirement [in terms of necessary age for making a blessing] is a child who knows to whom he is blessing (Bavli, Berakhot, 48a), as opposed to the rest of the mitsvot which have no requirement of knowing to whom one is making the blessing, such as phylacteries or the like. It is clear that the essence of a blessing is the knowledge of to whom the blessing is being made, and blessings were instituted for this purpose. This is the beginning of entering into Torah, as the verse says, “The beginning of wisdom is the fear of God” (Psalms 111:10). Fear of God is achieved through “I have placed God before me always” (Psalms 16:8), as Rabbi Moses Isserles wrote in a comment at the beginning of Oraḥ Ḥayyim. This explains why all blessings begin with direct, second-person, address (lashon nokhaḥ), because right at the beginning of the blessing God must be present (nokhaḥ) before a person’s eyes, as if God is standing in front of and commanding him. The conclusion is in third-person, because God immediately disappears, as the verse says, “Over his nestlings he hovers” (Deuteronomy 32:11), making contact and then moving away, as is known.
