Included in this idea of causing others to do good is the idea that one should say one’s blessings out loud, so that the listeners will hear and say Amen. This is especially true about the blessings made when one is called to read in the Torah scroll, where there are opinions that the blessing is considered in vain if the assembled people do not hear it, as these blessings are made on behalf of the assembled community, and it is only through these blessings that the community fulfils their own obligation. It is known that the one who answers Amen is greater than the one who made the blessing in the first place, and according to the merit of the one who answers so too will the merit of the one who causes him to answer, grow.
Also included in this is the idea that when standing with other people or at a meal, he should open his mouth with words of Torah. Even one who does not know how to say a word of Torah, should ask a wise man in the gathering even a small question about the Torah, and he will cause that because they start talking about Torah, they will continue, and he will cause them to have fulfilled the words of Chazal who said that “Three people who ate at the same table and said words of Torah over it, it is considered as if they ate from the table of Hashem!”.
