וְאַתָּה קָדוֹשׁ יוֹשֵׁב תְּהִלּוֹת יִשְׂרָאֵל
You are holy, the One enthroned upon the praises of Israel.
Uva l’Tziyon includes a version of kedusha called “kedusha d’sidrah.” The Talmud in Sotah (49a) says that after the Temple was destroyed, every day was more cursed than the one before. The Talmud asks: if things are always getting worse, what keeps the world going? It answers, the kedusha recited in Uva l’Tziyon and the “amen yehei shmei rabbah…” of the kaddish recited after Torah study.
