Musar do Lamentacje Jeremiasza 3:6

It is a duty to recite a benediction when setting out to study or to read the written Torah as well as to recite a benediction when setting out to study the oral Torah. The two benedictions are different, however, in their mystical dimensions. The benediction recited over the written Torah focuses on the awakening of the hidden light, imploring G–d to expand some of it so we may be enlightened by it. It is an example of the fact that any blessing is by definition an expansion of an already existing measure of blessing granted by G–d. The fact that we recite this blessing "awakens" the blessing, so to speak. The same will happen in the future when we can access this light completely. The benediction recited before studying oral Torah is an acknowledgement that this Torah has already developed like a fountain that keeps on gushing forth water, constantly adding new water. Similarly, our preoccupation with the oral Torah constantly affords us new insights, some of them never before articulated. It is these new insights which our Rabbis referred to when they said that G–d Himself quotes such insights taught by the scholars. The discussion in the Talmud as to why the earth was destroyed revolves around this concept. The purpose of creating the earth was that the earth should be "good," i.e. the world should be refined and that man should be clothed in garments of light, and that the light which is now hidden should pervade the whole universe. G–d hid this light upon observing the deeds of man. As a result the whole material the earth was constructed of coarsened, and man was forced to wear garments made of hide, etc. In spite of this coarsening process there was a small part of the earth which retained its original holiness, i.e. ארץ ישראל. Even this small corner of the earth which had retained its original holiness lost it, however, due to our sins, i.e. at the time of the destruction of the Holy Temple. At that time darkness descended even on this part of the earth, as the prophet Jeremiah tells us in Lamentations 3,6. Just as the light was removed immediately Adam had sinned, so in the case of Jerusalem. We read in Jeremiah 32,31: "This city has aroused My anger and My wrath from the day it was built until this day; hence it must be removed from My sight." This condition will continue until the land laid waste will be restored to be like גן עדן. I have repeatedly explained that terrestrial ארץ ישראל is "opposite" Celestial ארץ ישראל which is the mystical dimension of the oral Torah.
