9726. 'And you shall make for it a grating, a network' means the level of sensory perception, which is the last and lowest. This is clear from the meaning of 'a grating, a network' as external sensory perception, thus that which forms for a person the last and lowest level of life; and since this lowest level is meant by the grating it was placed all the way round the altar. Such sensory perception was represented by the grating because it first sifts so to speak and sorts out those things which enter the human mind and present themselves to the understanding and will, namely truths and forms of good. If the sensory perception is composed of good it does not let anything through other than forms of good, and truths derived from good, and rejects evils and the falsities arising from evil. For sensory perception is the actual ability to perceive things which belong to the understanding and to sense those which belong to the will as they exist on outermost levels, an ability that is perfectly fashioned for the affections for those things. The nature of all this may be illustrated by very many things in the body. Everywhere in the outermost parts within the body there are forms that resemble nets and there are so to speak gratings which sort out the things that flow towards them from the world. Those that are suitable are let through because they are desirable, and those that are unsuitable are rejected because they are loathsome. Extremely sensitive systems such as these exist in the stomach. These let through into the blood the suitable juices of the chyle, because these juices are useful and therefore desirable, and reject the unsuitable because they are harmful and therefore loathsome. The situation is similar with sensory perception, which is the last and lowest level of a person's life. But this level with a person has become totally wrecked, the reason why being that it stands right next to and is exposed to the world and is therefore the last to be regenerated, indeed scarcely anyone at the present day is able to be regenerated down to that level. As regards what the level of sensory perception is like with these people, see what has been shown already concerning it in 4009, 5077, 5081, 5084, 5094, 5125, 5128, 5580, 5767, 5774, 6183, 6201, 6310-6318, 6564, 6598, 6612, 6614, 6622, 6624, 6844, 6845, 6948, 6949, 7442, 7645, 7693, 9212, 9216.

Therefore if a person is to see and have an understanding of the truths of faith and the forms of the good of love he must be raised by the Lord above that level to more internal levels. But the sensory perception meant by 'the grating, the network' around the altar is the sensory perception belonging to the Lord's Divine Human, since the altar is representative of the Lord and of the worship of Him that springs from the good of love, 9714.

5094. 'The cupbearer and the baker' means regarding both kinds of sensory powers. This is clear from the meaning of 'the cupbearer' as the sensory powers subordinate to the understanding part of the mind, dealt with in 5077, and from the meaning of 'the baker' as the sensory powers subordinate to the will part, dealt with in 5078, which, as stated above in 5083, 5089, were cast aside by the interior natural. But it should be realized that the actual powers of the senses were not cast aside - that is to say, sight, hearing, smell, taste, and touch, for the life of the body is dependent on these - but the insights or thoughts, as well as the affections and desires, that are dependent on them. Objects belonging to the world enter a person's external or natural memory by way of his senses on the one hand and by way of his rational thought on the other. These objects then divide themselves off from one another in that memory; those entering through rational thought place themselves in a more internal position, whereas those entering through the senses do so in a more external one, as a consequence of which the natural comes to have two parts - the interior part and the exterior - as has also been stated above.

[2] The interior natural is what 'Pharaoh king of Egypt' represents, while the exterior natural is what 'the cupbearer and the baker' represents. The nature of the difference between the two becomes clear from the different ways they look at things, that is, from their thoughts and their conclusions based on those thoughts. The person who uses the interior natural to think with and to form conclusions is rational, and is so insofar as he has absorbed what comes to him through rational thought; but the person who uses the exterior natural to think with and form conclusions is governed by his senses, and is so insofar as he has absorbed what comes to him from sensory evidence. Such a person is called one governed by his senses, whereas the other is called one who is rational-natural. When a person dies he has the entire natural with him; and its form remains the same as that which it took in the world. He is also rational-minded to the extent he has absorbed ideas from rational thought, but sensory-minded to the extent he has absorbed ideas from his senses. The difference between the two is that, to the extent it has absorbed ideas from rational thought and made them its own, the natural looks down on the senses belonging to the exterior natural and controls them by disparaging and casting aside illusions formed by the senses. But to the extent that it has absorbed ideas formed by the bodily senses and made them its own the natural looks down on rational thought by disparaging this and casting it aside.

[3] An example of the difference between the two may be seen in the ability of the rational-natural man to comprehend that no one's life is self-existent but that it comes to him through an influx of life from the Lord by way of heaven, and the inability of one governed by the senses to comprehend the same. For the latter says his senses tell him and he can plainly see that his life is self-existent and that it is pointless to contradict the evidence of the senses. Let another example be given. The rational-natural man comprehends the existence of a heaven and a hell; but one governed by his senses denies the existence of these because he has no conception of another world purer than the one he sees with his eyes. The rational-natural man comprehends the existence of spirits and angels who are not visible to him; but one governed by the senses cannot comprehend the same, for he imagines that what he cannot see or touch has no existence.

[4] Here is another example. The rational-natural man comprehends that it is the mark of an intelligent being to have ends in view, and with foresight to be directing means towards some final end. When he looks at the natural creation from the point of view of the order of everything, he sees the natural creation as a complex system of means and realizes that an intelligent Supreme Being has given them direction, though to what final end he cannot see unless he becomes spiritual. But a person governed by his senses does not comprehend how anything distinct and separate from the natural creation can exist or how some Being superior to the natural order can do so. He has no notion of what exercising intelligence, exercising wisdom, having ends in view, or giving direction to means may be unless all these activities are being spoken of as natural ones; and when they are spoken of as such, his idea of them is like that of one who is designing a machine. These few examples show what is meant by the interior natural and the exterior natural, and by the powers of the senses being cast aside - not sight, hearing, smell, taste, and touch in the body, but the conclusions reached by these about interior matters.
