862. That 'it happened at the end of forty days' means the duration of the former state, and the beginning of the one that followed, is clear from the meaning of 'forty', see 730, where, the subject being temptation, the phrase 'forty days and forty nights' was used, which meant the duration of temptation. Here, since the subject is the state following temptation, 'forty days' is mentioned but not forty nights. The reason is that charity now starts to appear, which in the Word is compared to the day and is called the day. Faith however which precedes but has not yet been so joined to charity is compared to the night and is called the night, as in Genesis 1:16, and elsewhere in the Word. Faith is also called 'the night' in the Word because it receives its light from charity, just as the moon does from the sun. Faith is therefore also compared to the moon and is called the moon; and love or charity is compared to the sun and is called the sun. 'Forty days', or the duration of time meant by them, refers both to the things that precede and to those that follow; hence the statement 'at the end of forty days', which accordingly means both the duration of the previous state, and the beginning of the one being described now. This then begins the description of the second state following temptation of the member of this Church.

5092. 'Each his dream in one night' means regarding what the outcome would be, which to them lay in obscurity. This is clear from the meaning of 'a dream' as foresight and consequent foretelling - and because a foretelling is meant, so also is the outcome, it being the outcome that is foretold; and from the meaning of 'night' as obscurity. In the spiritual sense 'night' means a state of shade brought about through falsity that is the product of evil, 1712, 2353, and so also obscurity, that is to say, mental obscurity. The obscurity belonging to night in the world is natural obscurity, but the obscurity belonging to night in the next life is spiritual obscurity. Natural obscurity comes about because the sun of the world is absent and the light received from it is lost, whereas spiritual obscurity comes about because heaven's sun, which is the Lord, is absent and the light, that is, intelligence received from it, is lost. This latter loss does not arise because the sun of heaven sets as the sun of the world does, but because a person or a spirit is living amid falsity that is the product of evil. He himself moves away from that sun and brings obscurity to himself.

[2] An idea simply of night and of the obscurity that comes with it is sufficient to enable one to see how the spiritual sense and the natural sense of something are related to each other. Furthermore there are three kinds of spiritual obscurity - the first being that which is due to falsity that is a product of evil; the second being that which is due to ignorance of the truth; and the third being the obscurity in which exterior things dwell, compared with interior ones, and so the obscurity in which ideas formed by the senses and present in the external man dwell, compared with the rational concepts present in the internal man. All three kinds of obscurity arise however because the light of heaven, or intelligence and wisdom flowing from the Lord, is not received. This light shines unceasingly, but falsity that is a product of evil either rejects, smothers, or else perverts it; ignorance of truth receives only a little; while ideas formed by the senses that are present in the external man reduce it to a dim light by making it a general or ordinary one.
