848. When temptations have come to an end there is so to speak fluctuation. And if the temptations are spiritual it is fluctuation between truth and falsity, as also becomes quite clear from the fact that temptation is the starting point to regeneration. The purpose of all regeneration therefore is that a person may receive new life, or rather that he may receive life, and from not being a man may become one, that is, from being a dead man may become one who is alive. When therefore his former life, which is purely animal, is destroyed by means of temptations he cannot after temptations do other than fluctuate between truth and falsity. Truth belongs to the new life, falsity to the old. Unless the former life is destroyed and this fluctuation takes place, spiritual seed can never be implanted because there is no ground for it.

[2] Once that former life has been destroyed however, and this kind of fluctuation is taking place, a person knows almost nothing at all of what truth and good are. Indeed he scarcely knows of the existence of any such thing as truth. Take, for example, the situation in which a person considers whether he is able to perform from the proprium any good deeds that stem from charity, that is, good works, as people call them, and whether merit rests in his proprium. He is in that case in such obscurity and darkness that when told that nobody is able to do anything good from himself, that is, from his proprium, still less merit anything, and that all good comes from the Lord and all merit is the Lord's, it must inevitably astonish him. The same applies to all other matters of faith. Nevertheless that obscurity or darkness in which he dwells is slowly and gradually lightened.

[3] Regeneration is exactly like when a person is born as an infant. At this point he is living in the greatest obscurity, knowing virtually nothing. This being so, general ideas of things flow in first, which gradually become more definite as specific ideas are introduced into the general, and further still as yet more detailed ideas are introduced into the specific. Detailed ideas light up the general so that he knows not merely of their existence but also the nature of them. A similar process takes place with everyone emerging from spiritual temptation; and the state is similar in the case of people in the next life who have been under the influence of falsities and who are now being vastated. This state is called fluctuation and is described here as 'the waters receding, going back and forth'.

857. That 'the waters were going down and abating' means that falsities started to be dispersed is clear from the actual words themselves and from what has been stated just above, at verse 3, where it is said that 'the waters receded, going back and forth', whereas in this verse it is said that 'the waters were going down and abating'. The latter as well as the former means fluctuations between truth and falsity, though the present statement means that those fluctuations were becoming less pronounced. As has been stated, during the fluctuations that follow temptation a person does not know what truth is, but as the movements gradually come to an end so the light of truth appears. The reason for this is that as long as a person's state is such, the internal man cannot function, that is, the Lord cannot function by way of the internal into the external. The internal contains remnants, which are affections for good and for truth deriving from it, which have been dealt with already. The external contains evil desires, and falsities deriving from these. As long as these external things have not been subdued and done away with, no road is open for goods and truths to pass from the internal, that is, from the Lord by way of the internal.

[2] A further purpose of temptations therefore is that the external side of a person may be subdued and so made subservient to the internal. This may become clear to anyone from the fact that as soon as a person's loves are assaulted and crushed, as they are in times of misfortune, sickness, and mental illness, his evil desires start to subside. And as they subside he begins to talk of more devout things. But as soon as he goes back to his previous state, his external man takes control again and he gives scarcely any thought to such matters. It is similar in the final hour of death when bodily things start to fade. From these considerations anyone may see what the internal man is and what the external man, also what remnants are, and how too the desires and pleasures that belong to the external man hinder the Lord's functioning by way of the internal man. From this also anyone may discern what temptations, that is, the inward pains termed the pricks of conscience, accomplish; they take place so that the external man may become subservient to the internal. The external man is made subservient solely to ensure that affections for good and truth are not hindered, halted, and stifled by evil desires and by falsities deriving from them. The subsidence of evil desires and falsities is here described by 'the waters going down and abating'.
