גָּלוּי וְיָדֽוּעַ לִפְנֵי כִסֵּא כְבוֹדֶֽךָ שֶׁאִם יִפָּתֵֽחַ אֶחָד מֵהֶם אוֹ יִסָּתֵם אֶחָד מֵהֶם אִי אֶפְשַׁר לְהִתְקַיֵּם וְלַעֲמֹד לְפָנֶֽיךָ אֲפִילוּ שָׁעָה אֶחָת.

It is obvious and known in the presence of Your glorious throne4 that if one of them were ruptured, or if one of them were blocked, it would be impossible to exist and stand in Your Presence even for a short while.
