A person to whom Hashem has given more money than he needs must know that the money is not his but only a deposit for him to manage. The Holy One gave it to him so that he can do charity and kindness with his fellow Jews. It is not Hashem’s will that one person should be extraordinarily wealthy while his fellow Jews dwell in poverty. The wealthy Jew is but a caretaker who must be concerned for the welfare of others and do kindness with them.
And even if occasionally his involvement in charitable matters causes him some small loss, the person should pay no attention to that and he should not feel discouraged, for it is known that in every business there are occasional losses, yet people do not refrain from going into business. This is certainly true with this very “profitable business” of fulfilling Hashem’s will. Just as a person is not upset about the expense of purchasing teffilin or of building a sukkah, he should likewise not be upset about any financial loss he may suffer as a result of the mitzvah of doing kindness.
