“The reward of the bride—pressure” (Berachot 7). A “bride” means faith, and all the benefit is that when a person feels pressure in Torah and Mitzvot [commandments], he has a place to accept faith above reason.
“The reward for hearing—understanding.” The reward of the Torah, called “hearing,” is specifically knowledge and not faith, since when one learns Torah but does not understand what is written in it, this is called Mitzva [commandment] and not “Torah.”
“The reward for a house of mourning—silence.” Where there is grief, the benefit is that one can justify Providence and say, “Silence, such was My thought.”
“The reward for fasting—almsgiving.” But Shmuel says that one who fasts is called “a sinner,” and we should interpret that because the purpose of creation is to do good to His creations, it follows that he does the opposite of the goal. Therefore, he is called “a sinner.”
However, when one gives almsgiving, it shows that now he is engaging in fear of heaven, called “faith.” This is as it is written, “And he believed in the Lord and considered for him as Tzedakah [righteousness/charity].” At that time, he knows about himself that this is not wholeness and he must be rewarded with the Torah, for then he receives the light concealed in the Torah, which is the purpose.
