On the successive states of the regenerate life in general, involving states of conflict against evil succeeded by states of rest.

The first subordinate state is one of deliverance from evil, involving the interior reception of truth conjoined with good, purification, and the arrangement of truths under good. Verses 4-8.

The second subordinate state is that of the implantation of truth in good. Verses 9-22.

Concerning revelation in consequence. Verses 23-25.

Also concerning the plenary removal of evil in consequence. Verses 26-32.

The third subordinate state is that of the implantation of good, involving gladness and joy of heart in all completeness and holiness, with states of peace and rest from the lowest principles to the highest, which are perpetually renewed. Verses 33-34.

In general, trees represent the deepest and most significant intellectual concepts: the ones that come to us most directly from the Lord. This varies depending on us and our states: the people of the Most Ancient Church, who were in a state of loving the Lord, understood truth automatically and internally through what the Writings call "perception"; people in lower states (including most of us) have to work a little harder to learn it from the Word and by willing to follow the Lord. In other parts of the Bible, especially in the prophets and New Testament parables, the meaning of "tree" is broader, meaning not just a person's intellectual concepts but the whole person.

'Trees,' as in Joel 1:10-12, signify knowledges.
