Pillar Quotes
When [ Abraham ] the "Pillar of the World" appeared, he became convinced that there is a spiritual Divine Being, which is not a body, nor a force residing in a body, but is the author of the spheres and the stars; and he saw the absurdity of the tales in which he had been brought up. He therefore began to attack the belief of the Sabeans, to expose the falsehood of their opinions, and to proclaim publicly in opposition to them, "the name of the Lord, the God of the Universe" (Gen. xxi. 33), which proclamation included at the same time the Existence of God, and the Creation of the Universe by God.
Maimonides
He saw the light gradually approaching him until it rested upon the tops of the trees. He beheld that the leaves of the trees were not consumed by it, although its brightness, apparently, was sufficient, as he at first thought, to consume everything before it. But the trees were not consumed by it, and it continued to descend until it rested upon him and enveloped him in its glorious rays. When he was thus encircled about with this pillar of fire his mind was caught away from every object that surrounded him, and he was filled with the visions of the Almighty, and he saw, in the midst of this glorious pillar of fire, two glorious personages, whose countenances shone with an exceeding great lustre. One of them spoke to him, saying, while pointing in the other, "This is my beloved Son in whom I am well pleased, hear ye him."
