Arcana Coelestia # 13
13. Not all people who are being regenerated reach this state. Some, indeed the majority nowadays, reach only the first. Some reach merely the second, others the third, fourth, or fifth. Seldom do any reach the sixth, and hardly anybody at all reaches the seventh.
Revelation 8:10-11
10
The third angel sounded, and a great star fell from the sky, burning like a torch, and it fell on one third of the rivers, and on the springs of the waters.
11
The name of the star is called "Wormwood." One third of the waters became wormwood. Many people died from the waters, because they were made bitter.
