After numerous attempts, Bilaam finally gave up. Rashi writes: "(Bilaam) saw each tribe settled on its own and not intermingling; he saw the openings of each (family's) tent misaligned with the neighbor's so that one should not infringe upon the tent of another .... he felt then in his heart not to curse them." We, as Jews, understand the concept of Indus - modesty, and family parity, so it is no wonder to us that our ancestors behaved in this fine manner. But what would a shameful degenerate like Bilaam gamer from such a sight, that impressed him so much so to the point of changing his wicked tune, of his own volition?

     The great R' Boruch'l of Mezhibuz zt"l responds with an esoteric explanation, citing the oft-quoted words of Chazal: פתחו לי פתח כחודה של מחט ואני אפתח לכס פתח כפתחו של אולם. - Open up for Me (with teshuva) an opening the size of a pin-head, and I will open for you an opening as wide as that of a banquet hall. Hashem wants us to make even a minor effort and He will do the rest to show His love for Klal Yisroel.

     This, then, is the meaning of Rashi's words, "He saw that their openings were misaligned" - this is a reference to the "פתח" - "Opening" that exists between Hashem and His chosen nation. Unfortunately, our openings remain small and distant, however, Hashem is always ready to enlarge His opening to allow us to return to the proper fold. When Bilaam saw this misalignment but still realized that through it all, the opening that Hashem creates for His people is as wide as the day is bright, he understood that there was no purpose to his evil curses, as Hashem would protect His people.
