Apocalypse Revealed # 214
214. "'And to anoint your eyes with eye salve, that you may see.'" This symbolically means, so as to heal their understanding, to keep them from profaning and falsifying genuine truths of wisdom.
Eyes symbolize the intellect, and the sight of the eyes intelligence and wisdom, as may be seen in no. 48. And since eye salve symbolizes medicine for it, it follows that to anoint the eyes with eye salve means, symbolically, to heal the intellect, so that it may see truths and become wise. Otherwise the genuine truths of the Word are profaned and adulterated.
Isaiah 47:1-3
1
"Come down, and sit in the dust, virgin daughter of Babylon; sit on the ground without a throne, daughter of the Chaldeans: for you shall no more be called tender and delicate.
2
Take the millstones, and grind meal; remove your veil, strip off the train, uncover the leg, pass through the rivers.
3
Your nakedness shall be uncovered, yes, your shame shall be seen: I will take vengeance, and will spare no man."
