Chasidut for Sukkah 103:4
כדדרש רבי יהודה לעתיד לבא מביאו הקב"ה ליצר הרע ושוחטו בפני הצדיקים ובפני הרשעים צדיקים נדמה להם כהר גבוה ורשעים נדמה להם כחוט השערה הללו בוכין והללו בוכין צדיקים בוכין ואומרים היאך יכולנו לכבוש הר גבוה כזה ורשעים בוכין ואומרים היאך לא יכולנו לכבוש את חוט השערה הזה ואף הקב"ה תמה עמהם שנאמר (זכריה ח, ו) כה אמר ה' צבאות כי יפלא בעיני שארית העם הזה בימים ההם גם בעיני יפלא
As R. Judah expounded: In the time to come the Holy One, blessed be He, will bring the Evil Inclination and slay it in the presence of the righteous and the wicked. To the righteous it will have the appearance of a towering hill, and to the wicked it will have the appearance of a hair thread. Both the former and the latter will weep; the righteous will weep saying, “How were we able to overcome such a towering hill!” The wicked also will weep saying, “How is it that we were unable to conquer this hair thread!” And the Holy One, blessed be He, will also marvel together with them, as it is said, “Thus says the Lord of Hosts, If it be marvelous in the eyes of the remnant of this people in those days, it shall also be marvelous in My eyes” (Zechariah 8:6).

In order to understand the relevance of this line, it is helpful to understand a verse in Proverbs 27,9 where Solomon says that שמן וקטורת משמח לב, “oil (for anointing) and incense gladden the heart.”
When dealing with matters involving holiness, the basic number used is the number 10. Already in the most ancient Kabbalistic text, the sefer yetzirah, the number ten is mentioned repeatedly as a contrast to the number eleven. The ten emanations, ספירות, different levels of holiness, are “matched” by ten levels of spiritually negative levels, the difference between the two being that the גורמים, causes, of the ten levels of holiness and the resulting holiness are viewed as part of something integral, whereas a similar “integrity” of cause and effect is not presumed to exist when spiritually negative forces and their causes are concerned. When we read in the sefer yetzirah about “ten levels of emanations and not eleven,” the author wishes to make the point that the causes of the sefirot and the sefirot themselves are not viewed as separate entities. When Moses speaks of a “distance,” of eleven days [in a spiritual sense, as in: ‘49 levels of ritual pollution,’ Ed.], the word חורב, [as distinct from Sinai. Ed.], is to be understood as symbolizing the סטרא אחרא, the ten spiritually negative forces that are the counterweight of the ten spiritually positive forces. The Israelites (priests) used to offer twice daily an incense offering known as קטורת, consisting of 11 different categories of fragrances. When Moses elaborates by saying that the “11 days” he refers to were in the direction of Mount Seir, the region of the Kingdom of Edom, it becomes clear that he referred to something that took the Israelites away from the spiritually lofty atmosphere of Mount Sinai in the direction of the spiritually totally polluted domain of Esau/Seir. This is a fitting introduction to Moses rebuking the Israelites in this Book. In the parlance of our sages, the evil urge is often referred to as הר, mountain, i.e. representing an almost insurmountable obstacle. It is also called שעיר as we know from Sukkah 52. [None of the seven names mentioned in the Talmud there is שעיר, Ed.] The Talmud there does say that the evil urge appears like a tall mountain to the righteous, whereas it appears as insignificant as a thin hair to the wicked.

The Talmud Eyruvin 53 relates that when Rabbi Yossi bar Avion wished to say something that only people familiar with him would understand, he would say: ”עשו לי שור במשפט בטור מסכן;“ he deliberately used some Hebrew words, שור, במשפט, which have a different meaning in Aramaic. Similarly, the word חרדל used by our sages for the seasoning Avraham provided for his guests is really a translation of the words הר דל, “a low hill.” In short, the Rabbi making excuses for the errors committed by the Jewish people, referred to the evil urge as an almost insurmountable obstacle, a tall mountain, whereas the urge to do good given to every human being, appeared like a low hill, so that it is not surprising that many Jews many times found it difficult to climb over the tall mountain in order to avoid sinning. When the sages spoke of the “seasoning” Avraham served his guests, this is merely a euphemism for saying that he tried to provide his guests with merits by the type of food served that would make it relatively easy to overcome the temptations offered by the evil urge. When the angels would reflect on this, they in turn, in the future, would tone down their accusations against sinful Jews, having realized through their visit on earth how difficult it is to fight these temptations.
