Halakhah for Berakhot 107:20

2) This belief bears great significance on our lives. It implies that there is no value in this world outside adherence to God, and we are thus enjoined to love Him “with all your heart, with all your soul, and with all your might.” The Sages (Berakhot 54a) interpret these words: “‘With all your heart’ – with both of your inclinations: your good inclination and your evil inclination,” because one’s evil inclination must be controlled to serve God, whether by force or by transforming it into good; “‘And with all your soul’ – even if it takes your life,” for one must be ready to give his life for his belief in God; “‘And with all your might’ (‘me’odekha’) – with all your money (‘mamonekha’)” – even one’s money should serve as a basis and a means to serve God, so that if it were demanded of a Jew to violate his religion or lose all his wealth, he would forfeit his money rather than defy his belief. Alternatively, they interpret, “‘With all your might’ – no matter what He metes out to you (‘be-khol mida u-mida she-Hu moded lekha’), be very grateful to him.”

And after this we will speak more generally about the rabbinic obligation of blessings. And that is: To recite a blessing before eating and drinking of anything that has any [good] taste to the palate - and so too, afterwards. And so [too,] they obligated us to recite a blessing over every good smell that we smell before smelling, but not after it. And the general principle of the thing is that they fixed a blessing on everything from which the body derives pleasure. And so [too,] did they obligate us (Pesachim 7b) to bless God and to admit [His goodness] over all the good that He has granted us in our doing His precious commandments. And they said that we recite a blessing over them before their doing. And the matter, according to my opinion, is like the reason mentioned adjacently about the reading of the Torah. And so [too,] they obligated us to recite blessings in praise of the Creator over His very mighty deeds, as is mentioned in the chapter [entitled] Haroeh (Berakhot 54a).
