We can now further appreciate how the books’ release leads to the collective release of all Jewry, the ultimate Redemption; as it is written explicitly, “Tziyon (the Jews) will be redeemed with Mishpat (“justice”; a reference to Torah study).” In other words, specifically through studying Torah, an activity which truly expresses the books’ true victory and redemption, we affect the release of “Tziyon,” the Jewish people; especially when we study Mishnah – as our Sages state, “The exiles will be ingathered only in the merit of the study of Mishnah.”
[See there, footnote 15, quoting the Alter Rebbe, who rules that nowadays, even the study of the laws set down by the Tur and Shulchan Aruch is considered “the study of Mishnah.” The Rebbe adds that the Mishneh’s redemptive power also extends to the study of these works.]
Torah study’s redemptive quality is further emphasized when we study the texts which were redeemed on Hei Teves. [“Even the ingathering of the exiles that is accomplished through the study of Mishnah, is further emphasized by specifically using copies of Mishnah (and other Halachic works) from among the books that were released on Hei Teves. After all, the redemptive quality of studying Mishnah is due to its elevation of the divine sparks that are scattered throughout Creation. Further, as discussed earlier, through redeeming Torah books, their ability to redeem the sparks is likewise increased.” – footnote 18]
... Our very act of making a resolution in this regard – when Hashem sees that the resolutions are truthful and will certainly be kept – contains this redemptive power; it is as if the books have actually been studied. [“The resolutions will be kept; especially since they are being made in a sacred location and a “threefold” structure: a house of prayer, Torah and good deeds.” – footnote 21] (Eve of Hei Teves 5752; Hisva’aduyos p.60)
