Arcana Coelestia #47
47. That these words contain arcana concerning regeneration becomes additionally clear from the fact that verse 24 above spoke of the earth bringing forth 'living creatures, beasts, and wild animals of the earth', while in the verse that followed the order was different, namely that God made the wild animals of the earth first and then the beasts. Indeed a person does first produce things so to speak from himself, and continues to do so until he becomes celestial. And so regeneration begins with the external man and moves on to the internal. This is why there is a different order here, with external things coming first.
Heaven and Hell #51
51. ANY ONE SOCIETY IS HEAVEN IN LESSER FORM, AND EACH ANGEL IN THE LEAST FORM.
Any one Society is heaven in lesser form and each angel is heaven in the least form because it is the good of love and of faith that makes heaven, and this good is in every society of heaven and in every angel of a society. It does not matter that this good everywhere differs and varies. It is still the good of heaven. The difference is only that heaven is of one quality here and another there. So, when one is raised up into some society of heaven he is said to come into heaven, and those who are there are said to be in heaven, each in his own. All who are in the other life know this. Consequently, those who stand outside or below heaven, looking from a distance at companies of angels, say that heaven is in this or that place. It is comparatively like the governors, officials and servants in one palace or court. Although they dwell apart in their own apartments or rooms, one above, another below, still they are in one palace or court, each one in the performance of his own duty in the king's service. This makes evident the meaning of the Lord's words, that
In His Father's house are many mansions. John 14:2.
Also what is meant by
The dwelling-places of heaven,
And by
The heaven of heavens, in the Prophets
