9730. 'And you shall put it under the rim of the altar beneath' means that sensory perception on the last and lowest levels. This is clear from the meaning of 'a grating, a network', which was to be put under the rim of the altar, as the level of sensory perception, dealt with above in 9726; from the meaning of 'the rim', when it refers to sensory perception, as that which is last and lowest (external sensory perception forms for a person the last and lowest level of life, see 9726); and from the meaning of 'beneath' as outwardly, for by things that are higher those which are more internal are meant, and by things that are lower those which are more external are meant, 6952, 6954, 7814-7821, 8604, so that 'above' means inwardly and 'beneath' means outwardly. The words 'external sensory perception' are not used to mean the sensory powers of the body itself - its senses of sight, hearing, taste, smell, and touch - but the ability that depends directly on them. For a person is called sensory-minded if those bodily senses and their appetites govern what he thinks and desires and he looks no further. If he does look further to examine what the senses desire and what his senses lead him to think, he is said to be raised above the sensory level, or to be drawn away from it, and to think on a more internal level. This happens to those at the present day who are governed by the good of charity and faith; and when it happens, the sensory level becomes dormant and is deprived of the life and activity that the world and worldly objects stimulate there.

There are two directions in which the things composing a person's understanding and will can be oriented. One faces without, towards the world; the other faces within, towards heaven. With natural and sensory-minded people the things composing their understanding and will, that is, their thoughts and affections, are oriented towards the world; but with spiritual and heavenly-minded people their thoughts and affections are oriented towards heaven, and also alternately towards the world. When a person is being regenerated he pivots round to face within, and so far as he can be turned in that direction the person can be raised by the Lord towards heaven, to Himself, and can as a result be endowed with wisdom, faith, and love. For the person then leads his life on the level of the internal man, consequently on that of his spirit, and the external man is subordinate to the internal. But if a person does not allow himself to be regenerated all the thoughts and affections within him remain oriented towards the world, in which case he leads his life on the level of the external man, and the internal man is subordinate to the external, as happens when the external man produces reasonings that lend support to evil desires. These people are called natural-minded, and those who are interested only in the most external things are called sensory-minded. All this goes to show what anyone should understand by the level of sensory perception.
