10. This is by means of a deed, MEANING OFFERINGS. When it is not needed, for example, on Rosh Hashanah (the Jewish New Year), which is the Day of Judgment, which those of wicked tongues stand ready to DENOUNCE YISRAEL, IT IS NOT SUFFICIENT TO GIVE MERE OFFERINGS. Speech is required; that is, prayers and petitions. It is necessary to demonstrate deeds, as we have explained. And we learned with what these must be demonstrated. It is with the Shofar, in order to invoke another Shofar, WHICH IS BINAH. We produce through the sound OF THIS SHOFAR Mercy and Judgment together, all as is required. This is just like that highest Shofar, WHICH IS BINAH, that emitted a sound, WHICH IS ZEIR ANPIN, which is the inclusion OF CHESED, JUDGMENT AND MERCY together - SINCE TIFERET, WHICH IS ZEIR ANPIN, IS INCLUSIVE OF CHESED, JUDGMENT AND MERCY. To awaken Mercy, we awaken WITH THE BLOWING OF THE SHOFAR and break down the Prosecutors so that they shall have no dominion on that day. When Mercy is awakened, all the upper luminaries, THE SFIROT, illuminate from this side and from that side, MEANING FROM THE RIGHT AND LEFT. Then, "in the light of the King's countenance is life" (Mishlei 16:15).
