“These distinctions make sense only when AR [absolute perfection in some respects, relative perfection in all others] is assumed (hence Spinoza's failure, who assumed mere A). Just as AR is the whole positive content of perfection, so CW, or the conception of the Creator-and-the-Whole-of-what-he-has-created as constituting one life, the super-whole which in its everlasting essence is uncreated (and does not necessitate just the parts which the whole has) but in its de facto concreteness is created – this panentheistic doctrine contains all of deism and pandeism except their arbitrary negations. Thus ARCW, or absolute-relative panentheism, is the one doctrine that really states the whole of what all theists, if not all atheists as well, are implicitly talking about.”

My View of the World (1961)
Context: This life of yours which you are living is not merely a piece of this entire existence, but in a certain sense the whole; only this whole is not so constituted that it can be surveyed in one single glance. This, as we know, is what the Brahmins express in that sacred, mystic formula which is yet really so simple and so clear; tat tvam asi, this is you. Or, again, in such words as "I am in the east and the west, I am above and below, I am this entire world."

Context: The poet, described in ideal perfection, brings the whole soul of man into activity, with the subordination of its faculties to each other according to their relative worth and dignity. He diffuses a tone and spirit of unity, that blends, and (as it were) fuses, each into each, by that synthetic and magical power, to which I would exclusively appropriate the name of Imagination.

Upon the Sovereign Sun (362)
Context: The one absolutely, the Intelligible, the ever Preexisting, comprehending all the universe together within the One — nay, more, is not the whole world One living thing — all and everywhere full of life and soul, perfect and made up out of parts likewise perfect? Now of this double unity the most perfect part (I mean of the Unity in the Intelligible World that comprehends all things in One, and of the Unity encompassing the Sensible World, that brings together all things into a single and perfect nature) is the perfection of the sovereign Sun, which is central and single, and placed in the middle of the intermediate Powers. <!-- But coming after this, there exists a certain connection in the Intelligible World with the Power that orders and arranges all things in one. Does not the essence of the Fifth Body, which is turned, as it were by a lathe, in a circle, move around the heavens, and is that which holds together all the parts, and binds them to one another, uniting what is naturally united amongst them and also those parts that mutually affect each other. These two essences, which are the causes of mutual attraction and of union (whereof the one manifests itself in the Intelligible, the other in the Sensible creation) does the Sun thus concentrate into one. Of the former he imitates this power of embracing and containing all things in the Intelligible creation, inasmuch as he proceeds from that source; whilst he governs the latter, that which is perceptible in the world of Sense. Perhaps, therefore, the self-existent principle, which existed first in the Intelligible creation, and lastly in the Visible bodies of the heavens, is owner of the intermediate, self-created essence of the sovereign Sun, from which primal creative essence there descends upon the visible world the radiance which illuminates the universe.
