שִׁ֗יר לַֽמַּ֫עֲל֥וֹת אֶשָּׂ֣א עֵ֭ינַי אֶל־הֶהָרִ֑ים מֵ֝אַ֗יִן יָבֹ֥א עֶזְרִֽי׃
Cantique des degrés. Je lève les yeux vers les montagnes, pour voir d’où me viendra le secours.
Ba'al Shem Tov
It can happen that one is praying on a lowly level, and suddenly in a flash their soul is illuminated and rises to upper worlds, like a person ascending a ladder, as it is written (Psalms 43:3) "Send forth Your light and Your truth, they shall guide me," - referring to the supernal illumination.
