Rav Kook Orot HaKodash Vol. I, pp. 83-84
Know yourself, and your world; know the meditations of your heart, and of every thinker; find the source of your own life, and of the life beyond you, around you, the glorious splendor of the life in which you have your being.
The love that is astir in you –raise it to its basic potency and its noblest beauty, extend it to all its dimensions, toward every manifestation of the soul that sustains the universe, whose splendor is dimmed only because of the deficiency of the person viewing it.
Look at the lights, in their inwardness. Let not the names, the words, the idiom and the letters confine your soul. They are under your control, you are not under theirs.
Ascend toward the heights, because you are of mighty prowess, you have wings to soar with, wings of mighty eagles. Do not fail them, lest they fail you; seek for them, and they will at once be ready for you.
The forms that robe reality are precious and holy to us, and especially to all who are limited in their spiritual perception. But always, when we approach a life of enlightenment, we must not swerve from the perspective that light flows from the incomprehensible to the comprehensible, by way of emanation, from the light of the En Sof.
And we are summoned to share in the heavenly delight, in all the particularized perceptions, which are included in this universal whole, from which all the proliferations of life are engendered.
