The Universe is one, infinite, immobile. The absolute potential is one, the act is one, the form or soul is one, the material or body is one, the ting is one, the being is one, one is the maximum and the best. It is not generated, because there is no other being it could desire or hope for, since it comprises of all being. It does not grow corrupt, because there is nothing else into which it could change, given that it is itself all things. It cannot diminish or grow, since it is infinite.
This whole which is visible in different ways in bodies, as far as formation, constitution, appearance, colors and other properties and common qualities, is none other than the diverse face of the same substance - a changeable, mobile face, subject to decay of an immobile, permanent and eternal being.
Everything that makes diversity of kinds, of species, differences, properties… everything that consists in generation, decay, alteration and change is not an entity, but a condition and circumstance of entity and being, which is one, infinite, immobile, subject, matter, life, death, truth, lies, good and evil.
All things are in the Universe, and the universe is in all things: we in it, and it in us; in this way everything concurs in a perfect unity.
It is manifest that every soul has a certain continuity with the soul of the Universe, so that it must be understood to exist and to be included not only there where it liveth and feeleth, but it is also by its essence and substance diffused throughout immensity. The power of each soul is itself somehow present afar in the Universe. It is not mixed, yet is there in some presence.
Anything we take in the Universe, because it has in itself that which is All in All, includes in its own way, the entire soul of the world, which is entirely in any part of it.
This universal Intellect is the initiate, most real, peculiar and powerful part of the soul of the world. This is the single whole which filleth the whole, illuminating the Universe and directing Nature to the production of natural things, as our intellect with the congruous production of natural kinds.
We find that everything that makes up difference and number is pure accident, pure show, pure constitution. Every production, of whatever kind, is an alteration, but the substance remains always the same, because it is only one, one divine immortal being.

Excerpt from De la Causa [Of the Causes], 1584.

NATURE IS GOD IN ALL THINGS

There is one simple Divinity found in all things, everything has Divinity latent within itself. For she enfolds and imparts herself even unto the smallest beings. Without her presence nothing would have being, because she is the essence of the existence of the first unto the last being.
We animals, and plants, are living effects of Nature; this Nature is none other than God in all things. Think thus, of the Sun in the crocus, in the narcissus, in the heliotrope, in the rooster, in the lion… to the extent that one communicates with Nature, so one ascends to Divinity through Nature.
If He is not Nature herself, he is certainly the nature of Nature, and is the soul of the Soul of the World, if He is not the soul herself.
Of the eternal corporeal substance, which is not producible ex nihilo, nor reducible ad nihilum, but "fashionable" and formable, then a figure can be modified. In altering a substance the fortune is varied, but the elements remain what they where in substance.
This same principle, which is the true substance of all things, is eternal and incorruptible. Of this eternal corporeal substance, formed or deformed, always remains only that which cannot be subject to dissolution since it is the Universe, and the Universe is the only real Divinity.
