'Window' signifies truth in the light.

(Посилання: 1 Kings 6:4, 6:6, 6:8; Apocalypse Revealed 132; Arcana Coelestia 655; Ezekiel 40:16, 40:22, 40:25, 40:33, 40:36; Jeremiah 22:13-14; Zephaniah 2:14)

656. 'The door in the side' means hearing. This is by now quite clear and so there is no need to confirm it by similar examples from the Word. For the relationship of the ear to inner sensory organs is like that of a door at the side to a window above, or what amounts to the same, the relationship of hearing, which is the function of the ear, to the understanding, which is the function of an inner sensory power.
