Jewish Mysticism
“And the enlightened will shine like the splendor of the sky.” This refers to those who are engaged in [the study of] Torah and contemplate words of Torah with intention and meditation of the heart. The enlightened contemplate [words of Torah] but they do not contemplate the word alone. Rather, they contemplate the place upon which the word is dependent, for there is no word that is not dependent on another supernal mystery. He finds in this word another matter of the supernal mystery. From the speculum that does not shine a person can find and see the secret of the speculum that shines… This is [the import of] “like the splendor of the sky,” that is the sky which is known [that stands] upon the creatures below, for from within that sky one can contemplate that splendor that shines, the splendor of the supernal splendors, the splendor that comes forth from the supernal point, shining and sparkling with the radiance of the other lights to every side.
