שִׁ֗יר לַֽמַּ֫עֲל֥וֹת אֶשָּׂ֣א עֵ֭ינַי אֶל־הֶהָרִ֑ים מֵ֝אַ֗יִן יָבֹ֥א עֶזְרִֽי׃
[성전에 올라가는 노래] 내가 산을 향하여 눈을 들리라 나의 도움이 어디서 올꼬
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.
