The Talmud in masechet Shabbat teaches that women who are careful to light candles (especially on Shabbat) can affect their children's spirituality. Rav Kook, explains this aggadita very uniquely, as well as that which is written there, that there's also a connection between our childrens' education and our care to observe Tzitzit & Mezuza.
An innocent line in the gemara about "grabbing matzot at the Seder so children will stay awake", is open to 5 totally different explanations in the rishonim, where each one sees it as a springboard for his personal educational theory. Each of these chinuchi and psychological approaches will hopefully, not only keep our children at the seder, but also "on the derech" of Torah and Mitzvot, to stay religious for the rest of their lives. In addition to the Talmudic analysis, the she'ur includes humorous anecdotes and personal experiences, which were originally delivered at a Shabbat HaGadol Drasha.
