Angels do not fall. For they were created and exist to precisely serve The Divine Source.
They do not incarnate in the physical, and have no desire for experiencing the illusions of the physical planes.
The stories of fallen “angels” which have been repeated for thousands of years in humanity’s consciousness, are in fact about a few extraterrestrials, who decided to rebel and move away from the benevolent higher dimensional factions, like the federations and councils; which exist from the fifth to the seventh dimensions. ~KejRaj
