He Traced a Circle on the Face of the Deep
The carpenter stretches a line, marks the outline with a stylus, he makes it with a plane, marks the outline with a compass, and makes it in the form of man, human splendor to set in a temple (Isaiah 44:13).
When He traced a circle on the face of the deep… when He set to the sea its limit (Proverbs 8:27–9).
“Come and see: Every circle in the world is formed from the midst of the single point standing in its center” (Zohar Ḥadash 5b, Sitrei Otiyyot).
“From a single point you can extend the dimensions of all things. Similarly, when the concealed arouses itself to exist, at first it brings into being something the size of the point of a needle, from there it generates everything” (Rabbi Moshe de León, Sheqel ha-Qodesh, 23–26, translated in Matt, The Essential Kabbalah: The Heart of Jewish Mysticism, p. 69).
“When enclosed and hidden within itself, within the supernal point above, She [Binah] assumes the form of the letter ס (samekh), enclosed within and hidden, ascending above. And when She returns and sits רְבִיעָא (revi’a), crouching, over children below to suckle them, She assumes the form of the letter ם (mem), רְבִיעָא (revi’a), quadrilateral, enclosed in four directions of the world [the first appearance of the letter ס (samekh) in the Torah is in the word הַסֹּבֵב (ha-sovev), surrounds (Genesis 2:11), and its second appearance is in the word וַיִּסְגֹּר (va-yisgor), closed (ibid., 21), see Bereshit Rabbah 17:6]” (Zohar 2:127a).
