From The Wisdom of The Lubavitcher Rebbe
Words and condensation by Rabbi Tzvi Freeman.
The shofar is a cry not of a human being, but of an animal's horn.
From a place so essential and unbounded, so raw and primal,
that the mind ceases to ponder, the heart stands still.
From the raw essence of man a cry rips aside heaven's curtains
to reveal the raw essence of his Maker.
