Continuing the line of thought from a recent post....
To what extent is a man obliged to teach his son Torah? — Said Rav Yeudah in Shmuel's name:
E.g., [a person who once lived named] Zevulun, the son of Dan, whom his grandfather taught Mikra [Tanach], Mishnah, Talmud,
halachos and aggados. An objection is raised: If he [his father] taught him Mikra, he need not
teach him Mishnah; whereon Rava said: Mikra means Torah [We see that it is not necessary ot teach more than Mikra unlike what Rav Yehuda said]? — Like Zevulun thhe son of Dan, yet not
altogether so. Like Zevulun the son Dan, whom his grandfather taught: yet not altogether so, for whereas
there [he was taught] Mikra, Mishnah, Talmud, halachos and aggados, here [i.e., as a general rule]
Mikra alone [suffices].
[Kiddushin 30b]
There is a huge problem here. We are talking about how a fellow named Zevulun ben Dan was taught by his grandfather. So we know his name, his fathers name but NOT his grandfather's name. Apparently, the most important person here is the grandfather for he is the teacher, so why is his name omitted??
From here we see that a good teacher is "nameless" i.e. ego-less. It is not about him at all but about the success of the student. The grandfather's name isn't mentioned to teach us this lesson.
Rebbi, teacher, guide, remove your ego. It is about the person receiving - not you.
