Daughter of the Eye
“For within the eye of a human being appears a vision of the world, in all its revolving colors. The white in it is the vast ocean surrounding the world on all sides. Another color is dry land, encircled by water; as dry land stands in the midst of water, so does this color. Another, third color is in the middle; this is Jerusalem, center of the world. The fourth color is vision of the whole eye, called בַּת עֵינָא (bat eina), ‘pupil of the eye’ [lit., daughter of the eye], in which a visage appears—most glorious vision of all. This is Zion, central point of all, in which a vision of the whole world appears; there dwells Shekhinah—beauty of all, vision of all. The eye is inheritance of the world, so this one leaves it and that one acquires it and inherits it” (Zohar 1:226a).
“She appears like this ·☽, like a crescent moon, with a point in the center, that point absorbing light from the Sun to illuminate the entire body.
This is the mystery of the point that inheres in part of the eye—everything exists in the point located in the center, for it absorbs all the light to illuminate the whole eye. Similarly, Moon is illuminated only from one point that abides and is concealed in the center, even though it cannot be seen in Moon.
Come and see: Every circle in the world is formed from the midst of the single point standing in its center. Consequently, the circle of the Moon is from a single point concealed within Her in the center, fashioning all. The point located in the center absorbs all light, shining upon Her body, illuminating all” (Zohar Ḥadash 5b, Sitrei Otiyyot).
