52. As long as someone is a spiritual man, the dominion over him runs from external man to internal man, as is said here, 'They will have dominion over the fish of the sea, over the birds of the air', and over the beasts, and over all the earth, and over every creeping thing that creeps on the earth'. When however he becomes celestial and does what is good out of love, then the dominion over him runs from internal man to external man. This is how the Lord describes Himself, and so simultaneously the celestial man, who is a likeness of Him, in David,

You have given him dominion over the works of Your hands; You have put all things under his feet, flocks and all cattle, and also the beasts of the field, the birds of the air, ¹ and the fish of the sea, and that crossing the paths of the seas. Psalms 8:6-8.

Here therefore the beasts are mentioned first, the birds next, and the fish of the sea after that, for the reason that the celestial man starts with love which resides in the will. With the spiritual man it is different. With him fish and birds, which have to do with the understanding, the domain of faith, come first, while beasts come afterwards.

Footnotes:

Animals in the Bible generally refer to spiritual activity, the things we actually do on a spiritual level. "Cattle," as typically used in the Bible, mean a collection of domesticated animals owned by one person or group (including other animals along with cows). It makes sense, then, that cattle would represent the spiritual activities we "own" and have "domesticated."

What are the good things we like to see in ourselves and encourage? What true ideas do we keep in mind, ponder, and use in our decision-making? These can come in great varieties and from many different sources, just as a variety of animals could be part of "cattle," but the key is that we own them, care for them and use them.
