Musar su Proverbi 1:5

Seeing that the list of virtues which the Torah tries to teach us both in this portion and in all other portions is very lengthy, I am not able to record more than a tiny fraction of them in my comments on this as well as on the other פרשיות. The reader will no doubt apply to himself the verse from Proverbs 1,5: ישמע חכם ויוסף לקח, "The wise man will hear and increase learning."

But how wondrous was this teacher's virtue and dedication, that he taught for free, even more so, [to resort to] giving him a reward in order that he desired to learn. Indeed, the real worker finds in this place the main purpose for his efforts, work and discernment. For it says about those who desire [to learn], “The wise will hear wisdom and desire to add more ” (Mishlei 1:5), he will be driven by his desire to chase, to achieve and to understand. But the one who strays, when he is insistent of his own thoughts, and does not recognize his deficiencies, or, if it is too hard for him to separate [from his way], [then] if the worker leaves him, it is possible [for him] to descend to the deepest depths where there is no cure for his ailment. Therefore, only one certified in his dedicated service will approach him in conversation, until he recognizes what is before him, until he sees the area [in which] he has made a mistake, until he achieves an inclination of truth, and until he allows himself to clarify to the point of seeking truth all the days of his life. And not to be categorized among so many who merely begin [the path, but do not finish it], but to be of the group that stays strong until completion. Therefore, the moment he adjusts himself to this goal, his merit will be exceedingly great until “You will decree and it will be fulfilled” (Iyov: 22;28).

Behold, up till now I have encompassed many details of the particulars of Cleanliness. What has been stated should serve as an example to all of the other Mitzvot and Traits, "let the wise man hear and increase in learning, and the one who understands obtain counsel" (Mishlei 1:5).
