37. As for the statement that 'the lights will be for signs, and for set times, and for days, and for years', this contains more arcana than can be presented at this point, though no arcanum at all is visible in the sense of the letter. For now only this can be said: Change in spiritual and celestial things takes place both on general and on particular scales, and is comparable to changes that take place through the day and through the year. Changes through the day are from morning to midday, from then on to evening, and through the night to the morning. Changes in the year similar, from spring to summer, from then on to autumn, and through winter to spring. These bring changes in temperature and amount of daylight, and so in the fertility of the earth. Compared to such changes are the changes that take place in spiritual and celestial things. Life without changes and variations would lead to sameness, and so no life at all. Good and truth would not be recognized and identified, let alone perceived. In the Prophets such changes are called 'ordinances', as in Jeremiah,

[Thus] said Jehovah who gives the sun for light by day and the ordinances of the moon and of the stars for light by night, These ordinances will not depart from before Me. Jeremiah 31:35-36.

And in the same prophet,

Thus said Jehovah, If I have not established My covenant of day and night, the ordinances of heaven and earth . . . Jeremiah 33:25.

But these things will in the Lord's Divine mercy be dealt with at Genesis 8:12.

5339. 'And in the seven years of abundance of corn the land yielded bunches' means initial states when series of truths were multiplied. This is clear from the meaning of 'seven years' as initial states (for seven years in which there was an abundance of corn came first, followed by seven years in which there was famine - 'years' meaning states, see 482, 487, 488, 493, 893); from the meaning of 'an abundance of corn' as a multiplication of truth, dealt with in 5276, 5280, 5292 ('the land yielded' meaning that this multiplication took place in the natural - 'the land' here being the natural, as immediately above in 5338); and from the meaning of 'bunches' as series.

The role which the series meant by 'bunches' play is this: With a person who is undergoing reformation general truths are introduced first, then the particular aspects of those general truths, and after that the specific details of these particular aspects. Particular aspects are ranged in order beneath general truths, and specific details beneath particular aspects, 2384, 3057, 4269, 4325 (end), 4329 (middle), 4345, 4383, 5208.

[2] These arrays or ordered arrangements of truths are meant in the Word by bundles, which at this point are called handfuls or 'bunches'. They are nothing else than truths which have been multiplied and are then arrayed in or arranged into series. With people who are regenerate these series follow the same ordered patterns as those in which the communities in heaven exist; but in the case of those who are not regenerate and are incapable of becoming such they follow the patterns in which the communities in hell exist. Consequently a person who is governed by evil, and by falsity rooted in evil, is a miniature hell, whereas one who is governed by good, and by truth rooted in good, is a miniature heaven. But more, in the Lord's Divine mercy, will be stated elsewhere about these series.
