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'.
Face of the water
The face of the water (Genesis 1:2) signifies the knowledges of good and truth.
