The Sages in the holy Zohar speak extensively about the praise deserved by a person who brings merit to those who had been remiss. Look there and you will see wondrous things! Therefore, it is proper for every person to encourage his friends and acquaintances to bring them back to the good. How much greater is the obligation to bring merit to one’s own children, for the head of the family is responsible for them. One should therefore correct them verbally and in writing — if Hashem graced the person with the ability to write well; and if he merits, his words will be beneficial for some future generation. Even if it will touch just one of a thousand generation, it will be worth it, and it will have been worthwhile to come into this world just for that. But at the very least, a father should instruct and charge his children and descendants to guard the path of Hashem.
The great reward destined for one who brings merit to the public is well-known — that it is of the highest [endeavors] possible, to the point that our Sages said that sin does not come upon such a person. Therefore, how proper it is to bring merit to the Jewish people and to inform them about the path upon which they should walk and the deed they should do. Each person should encourage his fellow. Included in this is to look at the taleisim (prayer shawls) in the Synagogue, and if they are unfit, fix them. In any similar action, one who brings merit to the public, that merit is to his credit, and it is doing a chessed to his own soul, for one gets others to act is greater than the one who acts himself.
