9063. 'He shall send him away free for his tooth' means that it cannot serve the internal man any longer. This is clear from the meaning of 'sending away free' as releasing from service, thus not serving any longer, as above in 9061; and from the meaning of 'tooth' as the level of the senses, dealt with immediately above in 9062. The situation in these matters may be recognized from what has been shown just above in 9061 regarding the condition of the internal man when the external man has been injured. Its condition is similar when the sensory level has been injured, for this is the lowest level in the natural man. This level too must be regenerated if a person is to be regenerated completely, see 6844, 6845, 7645. It is clear to anyone that these regulations concerning the eye or the tooth of a male slave or a female slave contain arcana which nobody can see without the help of the internal sense. For without some hidden reason why would it be stipulated that slaves should be released and go free because of an eye or because of a tooth, but not because of other parts of the body if they were badly damaged? But that hidden reason is made evident when one knows what is meant in the spiritual sense by 'eye' and by 'tooth'. And when one knows that, the reason for the stipulation comes to light.

7645. 'And one will not be able to see the land' means a darkening of the whole natural mind as a result. This is clear from the meaning of 'not being able to see as a darkening, that is, the failure to perceive truth; and from the meaning of 'the land of Egypt' as the natural mind, as above in 7644. But a brief statement must be made to explain why, when the outermost contents of the natural are laid waste, the whole natural mind is darkened as a result. The interior parts of a person's mind reach down into and are based on its lowest and outermost levels, where all its consecutive parts reside together. When there is nothing on the lowest levels but falsity and evil, truths and forms of good flowing from the interior parts into those lowest levels are flowing into evils and falsities there, as a consequence of which they are themselves turned into evils and falsities there. Therefore nothing but falsity and evil is apparent in the whole of the natural. This is what a darkening of the whole natural mind as a result, meant by 'not being able to see the land', describes. Here also is the reason why, when they have undergone vastation, hellish spirits are limited to the outermost parts of the natural. The inferior light they have, which is called the light of understanding, is not unlike the inferior light of this world, which in the next life becomes utterly thick darkness at the presence of the superior light of heaven. Since the outermost part of the natural, called the level of the senses, is filled with illusions and resulting falsities, and with self-indulgence and resulting evils, 6844, 6845, and since the hells are lit by that inferior light, the Lord provides a person when he is being regenerated with the ability to be raised above that level of the senses to more internal levels, see 6187, 6317, 7442.
