קדיש - ליום הקדיש הכללי

Incidental to the mention of the elevated significance of the night watches, the Gemara cites a related story: It was taught in a baraita that Rabbi Yosei said: I was once walking along the road when I entered the ruins of an old, abandoned building among the ruins of Jerusalem in order to pray. I noticed that Elijah, of blessed memory, came and guarded the entrance for me and waited at the entrance until I finished my prayer. When I finished praying and exited the ruin, Elijah said to me, deferentially as one would address a Rabbi: Greetings to you, my Rabbi. I answered him: Greetings to you, my Rabbi, my teacher. And Elijah said to me: My son, why did you enter this ruin? I said to him: In order to pray. And Elijah said to me: You should have prayed on the road. And I said to him: I was unable to pray along the road, because I was afraid that I might be interrupted by travelers and would be unable to focus. Elijah said to me: You should have recited the abbreviated prayer instituted for just such circumstances. Rabbi Yosei concluded: At that time, from that brief exchange, I learned from him, three things: I learned that one may not enter a ruin; and I learned that one need not enter a building to pray, but he may pray along the road; and I learned that one who prays along the road recites an abbreviated prayer so that he may maintain his focus. And after this introduction, Elijah said to me: What voice did you hear in that ruin? I responded: I heard a Heavenly voice, like an echo of that roar of the Holy One, Blessed be He (Maharsha), cooing like a dove and saying: Woe to the children, due to whose sins I destroyed My house, burned My Temple, and exiled them among the nations.And Elijah said to me: By your life and by your head, not only did that voice cry out in that moment, but it cries out three times each and every day. Moreover, any time that God’s greatness is evoked, such as when Israel enters synagogues and study halls and answers in the kaddish prayer, May His great name be blessed, the Holy One, Blessed be He, shakes His head and says: Happy is the king who is thus praised in his house. When the Temple stood, this praise was recited there, but now: How great is the pain of the father who exiled his children, and woe to the children who were exiled from their father’s table, as their pain only adds to that of their father (Rabbi Shem Tov ibn Shaprut).

The Kaddish is great and awesome praise that the Men of the Great Assembly fixed after the destruction of the First Temple. It is a prayer about the desecration of the Blessed Name from the destruction of the Sanctuary, the decimation of the Holy Land, and the dispersion of Israel to the 4 corners of the earth. We pray 'let the Blessed name be magnified and sanctified' as the prophet said: "I will make myself greater and more sanctified and be known to the nations, and they will know that I am Hashem." As R. Yosi said at the beginning of Berakhot, once a Bat Kol was heard cooing like a dove and saying: 'Oy to the children, that because of their sins, I destroyed My house, and burned my temple, and exiled them...' And Eliahu the prophet said to him, that three times each day a Bat Kol like this is heard. And further, at the time Israel enters its synagogues and study halls, and they answer 'amen! yehei shmei raba...amen ! May His great Name be blessed', the Holy One of Blessing nods his head and says, 'happy is the King who is praised like this in His house. What it is to be a Father who exiled His children? And woe to the children who were exiled from the table of their Father.' And because of its elevated status, it was decreed that it [the Kaddish] would be recited in Aramaic, because in Babylonia they spoke this language. And thus, so that everyone would understand it, [the Kaddish] was established in the spoken tongue. And, additionally, there are hidden reasons for this.
