Musar for Berakhot 55:8

A man should occupy himself with the needs of the poor and go to their houses. For there are two good results that will come from this: the first, the reward of the Creator, and the second, the humbling of his arrogance, causing the contriteness of his heart. He should speak warmly to them and help them as much as he is able. And if he has nothing⁵³See Maimonides’ Laws of Charity. Compare Leviticus Rabbah Chapter 34:15 explaining the verse in Isaiah 58:10 "and if thou draw out thy soul to the hungry." R. Levi explained this to mean that if you have nothing to give him, console him with kind words. , let him help them with the words of his mouth, by interceding favorably for them and occupying himself with their work. He should repay good for the evil done to him by his enemies. When they come into his power let him not desire to avenge himself, but let him forgive them and do good to them, more than he would have done for them previously. When he begins to come to worship his God, he should not consider it as something which, if he wearies of it, he can put aside and not worry about it. But he should not draw near to the service of his God until he has agreed with his heart to concentrate diligently on it all of his days. And he should begin with a little in order to increase his worship every day, just as our Sages, of blessed memory, said (Berakhot 28a), “In matters of holiness one ascends rather than descends.”
