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'.
Matthew 17:2
2
He was transfigured before them. His face shone like the sun, and his garments became as white as the light.
