9051. 'Eye for eye' means if anything is injured by them in the inner part of the understanding. This is clear from the meaning of 'the eye' as the understanding, in this instance the inner part of it, the life of which is the life of faith. A person's understanding has an outer part and an inner part The outer part of his understanding is where thought that enters his awareness is, whereas the inner part is where thought that does not enter his awareness is, though it enters that of the angels. This part of the understanding is what the Lord enlightens when a person receives faith, for it exists in the light of heaven and holds within it a person's spiritual life. This is not made plainly evident to the person while in the world, but it is made so to that person in the next life when he becomes an angel among angels in heaven. In the meanwhile that life lies hidden within the thought belonging to the outer part of the understanding, producing there the holiness and reverence for the Lord, for love and faith in Him, for the Word, and for everything else that is the Church's. The reason why 'the eye' means the understanding is that the eye corresponds to the understanding; for the understanding sees in the light of heaven, but the eye sees in the light of the world. The things that the former eye, that is, the understanding, sees are spiritual, and its field of vision is the factual knowledge contained in the person's memory. But the things which the physical eye sees are earthly, and its field of vision consists in every object that appears in the world. Regarding 'the eye', that in the spiritual sense it means the understanding, and also faith since faith composes the life of the inner part of the understanding, see 2701, 4403-4421, 4523-4534.

[2] Anyone who does not know that 'the eye' is used in the Word to mean the understanding cannot know what the meaning is of the things which the Lord spoke concerning the eye in the Gospels, first of all these,

If your right eye causes you to stumble, pluck it out. It is better for you to enter the kingdom of God with one eye, than having two eyes, to be cast into the Gehenna of fire. Matthew 5:29; Mark 9:47.

Everyone recognizes that the eye should not be plucked out even if it does cause a person to stumble, and that no one enters the kingdom of God with only one eye. But 'the right eye' means falsity in a person's belief about the Lord; this is what must be plucked out. Then there are these things spoken by the Lord,

The lamp of the body is the eye. If therefore your eye is sound, your whole body will be full of light. If your eye is evil your whole body will be full of darkness. If therefore the light that is in you is darkness, how great is the darkness! Matthew 6:22-23; Luke 11:34.

Nor is 'the eye' used here to mean the eye, but an understanding composed of the truth of faith. This is why the eye is called 'the lamp of the body' and why the Lord says, 'If the light that is in you is darkness, how great is the darkness!' For 'darkness' in the spiritual sense is falsities constituting faith, 1839, 1860, 4418, 4531, 7688, 7711.

[3] There are these words too spoken by Him,

Why do you notice the speck which is in your brother's eye, but do not consider the plank that is in your own eye? Matthew 7:3-5.

'Noticing a speck in a brother's eye' means seeing something erroneous in a person's understanding of truth; 'the plank in one's own eye' is huge evil of falsity, since 'wood' in the internal sense means good and in the contrary sense evil, 643, 2784, 2812, 3720, 8354. Good is also represented in the next life by a plank, which is why those who pretend to have good within themselves are seen carrying a plank, walking in safety as they do so. If 'eye' and 'plank' did not have these meanings, would 'seeing a plank in an eye' have any meaning at all? If it is not known that 'eye' in the Word means the understanding of truth, which is faith, neither can it be known what is implied by the Lord's action when He healed the blind man,

He spat on the ground and made clay with His saliva, and said to him, Go, wash in the pool of Siloam. John 9:6-7.

Since all the Lord's miracles, like all Divine miracles, had to do with those things that belong to the Lord's kingdom and the Church, 7337, 8364, so did this miracle too.

4523. THE CORRESPONDENCE OF THE EYE AND OF LIGHT WITH THE GRAND MAN - continued

Everyone who has any knowledge about air and sound may know that the formation of the ear is determined wholly and completely by the nature of the modifications of these, so that the actual physical and material ear corresponds to such modifications. And everyone who has acquired any knowledge concerning the atmosphere and light knows that the actual physical and material eye is formed in such a way that it corresponds to the modifications of these. So perfectly do the ear and the eye correspond to them that any arcanum hidden within the natural existence of air and sound is inscribed on the organism of the ear, and any arcanum hidden within the existence of the atmosphere and light is inscribed on the organism of the eye.

[2] Consequently anyone who has studied anatomy and at the same time physics may know by investigation that other physical and material organs - not merely the sensory but also the motor ones, as well as the internal organs - correspond to things that are part of the natural world. Thus the whole body is an organ composed of the deepest arcana belonging to everything which exists within the natural world, and its formation is determined by the hidden forces by which all things act and the wonderful manner in which they flow. This was why the ancients called the human being a little world or microcosm.

[3] One who knows these things may also know that whatever exists in the world and in the natural system does not come into being of itself but from something prior to itself; and that this something prior cannot come into being of itself but from something even more prior; and so on back to Him who is the First, from whom in their ordered sequence things come into being. And because they come into being from Him they are also kept in being from Him, for being kept in being is constant coming into being. Consequently all things without exception, right down to the last that belong to the natural order, have not only come into being from the First but are also being kept in being from the First. For if every single thing were not constantly coming into being, and if this continuous connection extending from the First and so linked to the First did not exist, it would instantly fall to pieces and perish.
