During the Chmielnitzki Massacres (see entry for 4 Sivan), a Cossack mob gathered around the fortified town of Olyka. Among the Jews who had found refuge inside was R. David Halevi (the Taz), a refugee from the nearby city of Ostroh. As the Cossacks prepared to breach the walls, the Jews gathered in prayer in the synagogue. Weak and tired, R. David drifted off to an uneasy sleep, and in his dream he envisioned the verse, “I will protect this city to save it, for My sake and for the sake of My servant David” (II Kings 19:34). Indeed, the old cannons atop the walls miraculously fired spontaneously toward the enemy, who proceeded to flee (Minhagei Beis Alik, p. 752).

G‑d desires to have a presence in this world, and in each mitzvah we do, however it is done, He is there.
G‑d desires that His light shine in this world, and in every word of divine wisdom and every heartfelt prayer, His light shines.
G‑d desires yet more—that He be found here in all His essence, that which can neither be spoken nor kept silent, neither of heaven nor of earth, neither of being nor of not-being—that which transcends all of these and from which all extends.
And that is how He is found in a simple, physical deed that shines brightly with divine light.
