Shabbat contains the secret of unity, and therefore, on Shabbat, the light of unity shines. The principal and most auspicious time for fostering family unity is precisely during the Shabbat meals; in those moments, there is special heavenly assistance to attain family harmony and to create healthy relationships among all members of the household.
We must recognize that a healthy, stable, and proper relationship can be created and maintained only by establishing pleasant, respectful, eye-level, heart-to-heart dialogue between parents and their children. The relationship between them should not be authoritarian, like a commander to a soldier, but rather authoritative—on the one hand, clarifying to the child what we demand and expect of them, and on the other hand, responding to the child's needs.
Therefore, it is forbidden at the Shabbat table to be critical of anyone, especially not of one's children; criticism is a dangerous weapon, and whoever does not know how to wield it can cause destruction in his home.
Our task as parents is to reach into our children’s souls, to kindle their inner flame, to strengthen them, and to illuminate for them all the goodness in the world. To achieve the overarching goal of gathering and uniting all of Israel together, one must first unite his closest circle (his own household: his wife, his children, his parents); only thereafter is he granted from Heaven the power to broaden and enlarge those circles, until ultimately he will be privileged to unite the whole of the Jewish people.
During the Shabbat meal, between one course and the other, one must fill the meal with spiritual content—song, words of Torah, stories of the righteous, and pleasant conversation among all family members. At these exalted moments, it is certainly forbidden to speak slander, trivialities, or politics. When the meal is conducted thus, the table is elevated and offered up before the Holy One, blessed be He, and concerning it, the verse says: "And He said to me, 'This is the table that is before G-d.'"
At the time of Shabbat zemirot, a spirit of purity descends from the highest heavens upon every son and daughter seated at the Shabbat table, and through that power, they receive in their souls courage and strength to sanctify themselves and to stand firm against every hindrance!
Through the power of Shabbat songs, we can protect our children from the ills and dangers of our age and of the street—and fortify them with pathways into the world of Torah and the diligent study of it, implanting within them an unbounded sweetness in the study and pursuit of Torah. That sweetness is the guarantee that they become true children of Torah, cleaving to it and joyfully fulfilling its commandments!
