Arcana Coelestia # 861
861. Verse 6 And it happened at the end of forty days that Noah opened the window of the ark which he had made. 'It happened at the end of forty days means the duration of the former state, and the beginning of the one that followed. 'Noah opened the window of the ark which he had made' means a further state when the truths of faith appeared to him.
Fowl
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.
