Two Suns - The Sun of the Spiritual World and The Sun of the Natural World

Selection from Apocalypse Explained ~ Emanuel Swedenborg

The whole world, with each and every thing in it, came into existence and continues to exist from the Lord the Creator of the universe. There are two suns, the sun of the spiritual world and the sun of the natural world. The sun of the spiritual world is the Lord's Divine love, the sun of the natural world is pure fire. From the sun that is the Divine love every work of creation has begun, and by means of the sun that is fire it has been carried to completion.

Everything that proceeds from the sun that is the Divine love is called spiritual, and everything that proceeds from the sun that is fire is called natural. The spiritual from its origin has life in itself, but the natural from its origin has nothing of life in itself. And because from these two fountains of the universe all things that are in both worlds have come into existence and continue to exist, it follows that there is in every created thing in this world a spiritual and a natural, a spiritual as its soul and a natural as its body, or a spiritual as its internal and a natural as its external; or a spiritual as the cause and a natural as the effect. That these two in any particular thing cannot be separated every wise person knows, for if you separate cause from effect or the internal from the external, the effect or the external goes to pieces, as when the soul is separated from the body.

That there is such a conjunction in the particular and even in the most particular things of nature has not yet been known. It has not been known because of the existing ignorance respecting the spiritual world, the sun there, and heat and light there, and because of the insanity of sensual men in ascribing all things to nature, and rarely anything to God except creation in general; and yet not the least thing is possible or can be possible in nature in which there is not a spiritual. That this spiritual is in each and every thing of the three kingdoms of nature ...

What is Spiritual is Distinct from What is Natural

From Arcana Coelestia ~ Emanuel Swedenborg

There are three things which succeed one another in heaven, and which, in order that they may be conceived distinctly, are to be called by their names, which are "celestial," "spiritual," and "natural."  These three proceed there in order, one from another, and by the influx of one into the next successively they are connected together, and thereby make a one. The Divine of the Lord in the heavens, from the difference of its reception, is called by these names.
...
The successives in heaven - Most of the learned at this day have no other idea of successives, than as of what is continuous, or as of that which coheres by continuity. As they have this idea of the succession of things, they cannot conceive the nature of the distinction between the exteriors and interiors of man, nor consequently between the body and the spirit of man; and therefore when they think about them from these ideas, they cannot possibly understand that after the dispersion or death of the body, the spirit also is able to live under a human form.

But successives are not connected continuously, but discretely, that is, distinctly according to degrees; for interior things are wholly distinct from exterior, insomuch that exterior things can be separated, and yet the interior things still continue in their life. This is the reason why man can be withdrawn from the body and think in his spirit; or according to the form of speaking used by the ancients, can be withdrawn from sensuous, and raised toward interior things. The ancients also knew that when man is withdrawn from the sensuous things that belong to the body, he is withdrawn or raised into the light of his spirit, thus into the light of heaven. Hence also the learned ancients knew that when the body was dispersed, they would live an interior life which they called their spirit; and as they regarded that life as the very human life itself, they also knew from this that they should live under the human form. Such was the idea which they had of the soul of man; and as that life was akin to life Divine, they hence perceived that their soul was immortal; for they knew that that part of man which was akin to life Divine, and thus conjoined with it, could not possibly die.

But after those ancient times this idea of the soul and of the spirit of man disappeared, by reason, as said above, of the want of a just idea of successives. Hence also it is, that they who think from modern learning do not know that there is what is spiritual, and that this is distinct from what is natural. For they who have an idea of successives as of what is continuous, cannot conceive of the spiritual otherwise than as of a purer natural, when yet they are as distinct from each other as are the prior and the posterior, thus as that which begets and that which is begotten. From this it is that the distinction between the internal or spiritual man, and the external or natural, thus between man's internal thought and will, and his external thought and will, is not apprehended by such learned men. Hence neither can they comprehend anything of faith and love, of heaven and hell, and of the life of man after death.

But they who have a just and distinct idea of successives are able in some degree to comprehend that with a man who is being regenerated the interiors are successively opened, and that as they are opened they are also raised into interior light and life, and nearer to the Divine; and that this opening and consequent elevation is effected by means of truths Divine, which are vessels recipient of the good of love from the Divine. The good of love is that which immediately conjoins man with the Divine, for love is spiritual conjunction. Hence it follows that man can thus be more and more interiorly opened and raised in proportion as he is in the good of love from the Divine; and that conversely there is no opening and consequent elevation with the man who does not receive truths Divine; as is the case if a man is in evil.

A Life According to Truths Divine

Selection from Arcana Coelestia ~ Emanuel Swedenborg

Whether you say charity toward the neighbor, or truth from good, it is the same thing, because those who are in charity are in the life of truth, and a life of truth, that is, a life according to truths Divine, is charity.
