“Yet not a single one of the righteous withdrew from unity.”

The Sun My Heart (1996)
Context: There is no phenomenon in the universe that does not intimately concern us, from a pebble resting at the bottom of the ocean, to the movement of a galaxy millions of light years away. Walt Whitman said, "I believe a blade of grass is no less than the journey-work of the stars...." These words are not philosophy. They come from the depths of his soul. He also said, "I am large, I contain multitudes." This might be called a meditation on "interfacing endlessly interwoven." All phenomena are interdependent. When we think of a speck of dust, a flower, or a human being, our thinking cannot break loose from the idea of unity, of one, of calculation. We see a line drawn between one and many, one and not one. But if we truly realize the interdependent nature of the dust, the flower, and the human being, we see that unity cannot exist without diversity. Unity and diversity interpenetrate each other freely. Unity is diversity, and diversity is unity. This is the principle of interbeing.

Upon the Sovereign Sun (362)
Context: That divine and all-beauteous World, which from the highest vault of Heaven down to the lowest Earth is held together by the immutable providence of God, and which has existed from all eternity, without creation, and shall be eternal for all time to come, and which is not regulated by anything, except approximately by the Fifth Body (of which the principle is the solar light) placed, as it were, on the second step below the world of intelligence; and finally by the means of the "Sovereign of all things, around whom all things stand." This Being, whether properly to be called "That which is above comprehension," or the "Type of things existing," or "The One," (inasmuch as Unity appears to be the most ancient of all things), or "The Good," as Plato regularly designates Him, This, then, is the Single Principle of all things, and which serves to the universe as a model of indescribable beauty, perfection, unity, and power. And after the pattern of the primary substance that dwells within the Principle, He hath sent forth out of Himself, and like in all things unto Himself, the Sun, a mighty god, made up of equal parts of intelligible and creative causes. And this is the sense of the divine Plato, where he writes, "You may say (replied I) that I mean the offspring of the Good, whom the Good has produced, similar to itself; in order that, what the Good is in the region of intelligence, and as regards things only appreciable by the mind, its offspring should be the same in the region that is visible, and in the things that are appreciable by the sight." For this reason I believe that the light of the Sun bears the same relation to things visible as Truth does to things intelligible. But this Whole, inasmuch as it emanates from the Model and "Idea" of the primal and supreme Good, and exists from all eternity around his immutable being, has received sovereignty also over the gods appreciable by the intellect alone, and communicates to them the same good things, (because they belong to the world of intelligence), as are poured down from the Supreme Good upon the other objects of Intelligence. For to these latter, the Supreme Good is the source, as I believe, of beauty, perfection, existence, and union; holding them together and illuminating them by its own virtue which is the "Idea" of the Good.

"Man's Glassy Essence" in The Monist, Vol. III, No. 1 (October 1892)
Context: The consciousness of a general idea has a certain "unity of the ego" in it, which is identical when it passes from one mind to another. It is, therefore, quite analogous to a person, and indeed, a person is only a particular kind of general idea.

The Saviors of God (1923)
Context: We must understand well that we do not proceed from a unity of God to the same unity of God again. We do not proceed from one chaos to another chaos, neither from one light to another light, nor from one darkness to another darkness. What would be the value of our life then? What would be the value of all life?
But we set out from an almighty chaos, from a thick abyss of light and darkness tangled. And we struggle — plants, animals, men, ideas — in this momentary passage of individual life, to put in order the Chaos within us, to cleanse the abyss, to work upon as much darkness as we can within our bodies and to transmute it into light.
