Hassidout sur Le Cantique des Cantiques 4:15

מַעְיַ֣ן גַּנִּ֔ים בְּאֵ֖ר מַ֣יִם חַיִּ֑ים וְנֹזְלִ֖ים מִן־לְבָנֽוֹן׃

une fontaine des jardins, une source d’eaux vives, un ruisseau qui descend du Liban.

Likutei Moharan

And because of this we say the berakhah on [hearing] the chatzotzrot and voice of shofar "...שֶׁכּחוֹ וּגְבוּרָתוֹ וְכוּ'/that [the world is filled with His power and mighty deeds]." And the gevurot/mighty deeds are aspect of power and gevurah/strength, for the man emits the sound with great force, and this sound hits the rainclouts, i.e. aspect of brains, from which "טִפִּין טִפִּין/droplets by droplets" go down, as written in the Zohar (Pinchas daf 235): "בְּאֵר מַיִם חַיִּים וְנוֹזְלִים מִן לְבָנוֹן/a well of living waters, and flowing streams from Lebanon" (Song 4) -- from the white of the brains.
