Our Tefillot were structured around Brachot. The rules of Brachot reveal the structure of the Brachot and what parts of the Brachot that lead to a better understanding of our Tefillot.
Rules 1 and 2 Of Brachot: That a Jew must recite 100 Brachot each day and that a Bracha that does not refer to G-d's name nor His hegemony is not a valid Bracha.
