על החוקים לפרטיהם, ספר א ח׳On the Special Laws, Book I 8

1[41] It was this which Moses the sacred guide, most dearly beloved of God, had before his eyes when he besought God with the words, “Reveal Thyself to me.”  In these words we may almost hear plainly the inspired cry “This universe has been my teacher, to bring me to the knowledge that Thou art and dost subsist. As Thy son, it has told me of its Father, as Thy work of its contriver. But what Thou art in Thy essence I desire to understand, yet find in no part of the All any to guide me to this knowledge.
ב׳
2[42] Therefore I pray and beseech Thee to accept the supplication of a suppliant, a lover of God, one whose mind is set to serve Thee alone; for as knowledge of the light does not come by any other source but what itself supplies, so too Thou alone canst tell me of Thyself. Wherefore I crave pardon if, for lack of a teacher, I venture to appeal to Thee in my desire to learn of Thee.” He replies,
ג׳
3[43] “Thy zeal I approve as praiseworthy, but the request cannot fitly be granted to any that are brought into being by creation. I freely bestow what is in accordance with the recipient; for not all that I can give with ease is within man’s power to take, and therefore to him that is worthy of My grace I extend all the boons which he is capable of receiving.
ד׳
4[44] But the apprehension of Me is something more than human nature, yea even the whole heaven and universe will be able to contain. Know thyself, then, and do not be led away by impulses and desires beyond thy capacity, nor let yearning for the unattainable uplift and carry thee off thy feet, for of the obtainable nothing shall be denied thee.”
ה׳
5[45] When Moses heard this, he addressed to Him a second petition and said, “I bow before Thy admonitions, that I never could have received the vision of Thee clearly manifested, but I beseech Thee that I may at least see the glory that surrounds Thee, and by Thy glory I understand the powers that keep guard around Thee, of whom I would fain gain apprehension, for though hitherto that has escaped me, the thought of it creates in me a mighty longing to have knowledge of them.”
ו׳
6[46] To this He answers, “The powers which thou seekest to know are discerned not by sight but by mind even as I, Whose they are, am discerned by mind and not by sight, and when I say ‘they are discerned by mind’ I speak not of those  which are now actually apprehended by mind but mean that if these other powers could be apprehended it would not be by sense but by mind at its purest.
ז׳
7[47] But while in their essence they are beyond your apprehension, they nevertheless present to your sight a sort of impress and copy of their active working. You men have for your use seals which when brought into contact with wax or similar material stamp on them any number of impressions while they themselves are not docked in any part thereby but remain as they were. Such you must conceive My powers to be, supplying quality and shape to things which lack either and yet changing or lessening nothing of their eternal nature.
ח׳
8[48] Some among you call them not inaptly ‘forms’ or ‘ideas,’  since they bring form into everything that is, giving order to the disordered, limit to the unlimited, bounds to the unbounded, shape to the shapeless, and in general changing the worse to something better. Do not,
ט׳
9[49] then, hope to be ever able to apprehend Me or any of My powers in Our essence. But I readily and with right goodwill will admit you to a share of what is attainable. That means that I bid you come and contemplate the universe and its contents, a spectacle apprehended not by the eye of the body but by the unsleeping eyes of the mind. 
י׳
10[50] Only let there be the constant and profound longing for wisdom which fills its scholars and disciples with verities glorious in their exceeding loveliness.” When Moses heard this, he did not cease from his desire but kept the yearning for the invisible aflame in his heart.
