Arcana Coelestia #62
62. The stages and states of the regeneration of man - both of mankind and of the individual person - divide into six and are called the days of his creation. Gradually from being no man at all, he first becomes something, though only little, then something more, until the sixth day is reached, when he becomes 'an image'.
Arcana Coelestia #10366
10366. 'Work shall be done for six days' means the state which comes before and is preparatory to the heavenly marriage. This is clear from the meaning of 'the six days which come before the sabbath' as the state which comes before and is preparatory to the heavenly marriage, dealt with in 8510, 8888, 9431, the heavenly marriage being the joining together of goodness and truth in a member of the Church and in an angel of heaven, and in the highest sense the union of the Divine itself within the Lord's Human, see 10356. And 'the work of six days' means the state which comes before, 10360.
