Humility born from confronting pride

ברש"י עץ ארז ואזוב שהגבוה שחטא ישפיל כאזוב.

In Rashi: "cedar wood and hyssop" - that the lofty one who sinned should lower himself like the hyssop.

The Sefas Emes cites Rashi on the parah adumah (red heifer): the tall cedar and the lowly hyssop teach that a person who sinned through haughtiness must humble himself down to the level of the lowly hyssop.

וקשה למה לי ארז.

And it is difficult: why do we need the cedar at all?

If the lesson is humility, why include the tall cedar in the mixture - the hyssop alone would seem to suffice to symbolize lowliness.

רק שצריך להיות השפלות מתוך זה הגיאות שע"י שמיישב עצמו איך מלאו לבו להתגאות בפני אדון הכל.

Rather, the lowliness must come out of the very haughtiness - for through a person's reflecting on how his heart filled him with the audacity to be arrogant before the Master of all.

The cedar (gaavah, haughtiness) is essential to the cure: genuine humility is born precisely from confronting one's own pride and asking how one dared to be arrogant in the presence of the Ribono shel Olam.

עי"ז עצמו צריך לבוא לשפלות ובושה והכנעה.

Through this very reflection he must come to lowliness, shame, and submission.

That honest reckoning with his own arrogance is itself what drives him to shiflus (lowliness), embarrassment, and hachna'ah (submission) before Hashem.

וזה תיקון חטא הגיאות:

And this is the rectification of the sin of haughtiness.

True teshuvah for gaavah is not simply becoming lowly, but allowing one's awareness of the pride itself to generate the humility - that is its tikkun.

Summary: In the parah adumah the cedar and hyssop together teach that the cure for haughtiness must grow out of the haughtiness itself. When a person reflects on how he dared to be arrogant before the Master of all, that very reckoning brings him to genuine lowliness, shame, and submission - and that is the true tikkun for the sin of gaavah.
