Fowl signify spiritual truth; a bird, natural truth; and a winged thing, sensual truth. Fowl of heaven, as in Hosea 2:18, signify the affections of truth; and reptiles of the earth, the affection of the knowledges of truth and good. Fowl signify thoughts, and all that creeps on the ground, the sensual principle. Fowl signify intellectual things.

10. Such spirits as have confirmed themselves during their life in the world in the belief that the good they do and the truth they believe is from themselves, or is appropriated to them as their own (which is the belief of all who place merit in good actions and claim righteousness to themselves) are not received into heaven. Angels avoid them. They look upon them as stupid and as thieves; as stupid because they continually have themselves in view and not the Divine; and as thieves because they steal from the Lord what is His. These are averse to the belief of heaven, that it is the Divine of the Lord in the angels that makes heaven.
