6141. 'And the ground may not become a waste' means that the mind must be cultivated with facts known to the Church. This is clear from the meaning of 'the ground' as the receptacle of truth, as above in 6135-6137, the actual receptacle being the mind, in this instance the natural mind since it is the ground of Egypt; and from the meaning of 'being laid waste' as a situation in which there is no truth to be seen, at this point no facts known to the Church, for 'the Egyptians' means the facts known to the Church, 4749, 4964, 4966, 6004, which are also the truths present in the natural. 'The land of Egypt' means the natural mind where factual knowledge resides, see 5276, 5278, 5280, 5288, 5701, and therefore 'the ground of Egypt' means that mind specifically. This now explains why 'the ground may not become a waste' means that the mind must be cultivated with facts [known to the Church].

5278. 'And all the abundance of corn in the land of Egypt will be thrust into oblivion' means the removal of truth and the seeming deprivation of it in both parts of the natural. This is clear from the meaning of forgetting or 'being thrust into oblivion' as a removal and the seeming deprivation that results from this; from the meaning of 'the abundance of corn' as the multiplication of truth, that is, truth that has been multiplied, dealt with just above in 5276; and from the meaning of 'the land of Egypt' as the natural mind or a person's natural, both parts of it in this case, as just above in 5276.

[2] The reason forgetting or 'being thrust into oblivion' means a removal and seeming deprivation is that something akin to this happens to the memory and to thought that relies on it. The actual matters that a person is thinking about are immediately beneath his attention, while related matters spread out in order around them, extending to unrelated ones furthest away, which at that time are in oblivion. Matters of a contrary nature are separated from these, hanging downwards and revealing themselves underneath, where they serve to counterbalance what is above them. This ordered arrangement is effected by means of good flowing in. Such is the way in which the whole of a person's thought is ordered. The truth of this can be seen from people's thoughts in the next life. There in the light of heaven it is quite normal for people's thoughts to be presented sometimes in a visual manner, at which times the form in which those thoughts are arranged is demonstrated. From this it may be seen that 'forgetting' in the internal sense means nothing else than a removal and seeming deprivation.
