48. From these considerations it is now clear that the fifth state is one in which a person speaks from faith which is part of the understanding and in so doing confirms himself in truth and good; and that what he produces at that point are the animate things called 'the fish of the sea and the birds of the air. ¹ It is also clear that the sixth state exists when he utters truths and performs good deeds from faith which is part of the understanding and so from love which is part of the will. What he produces at that point is called a living creature and a beast. And because at that point he begins to act both from faith and from love simultaneously, he becomes a spiritual man, who is called an image; and this is dealt with next.

Footnotes:

'Grass' is natural truth, and 'flower of the field' is spiritual truth, as in Isaiah 40:5, 6. Green grass, in the Word, signifies the good and truth of the church, and of faith, which first springs up in the natural man. This is also signified by 'herb in the field.' Grass and the pulse of the herb, as in Psalm 32:2, signify what is most vile. Grass signifies science from a spiritual origin, or that by which spiritual truth is confirmed. 'Reeds and rushes' signify science from a sensory origin, or the things which confirm the fallacies of the senses, as in Isaiah 25:7. This science, considered in itself, is only a part of the lowest natural degree, which may be justly called material and bodily, in which there is little or no life. Green grass also signifies that which is alive with man. 'Grass burnt up' signifies the things which are dead in him. Grass signifies the scientific principle. Just as green grass serves animals for support, spiritual truth serves men for spiritual nourishment.
