When does the soul leave the body?

 

You have often heard from survivors how their lives seemed to flash before them. 

In his Letters from the Spirit World, Spirit Herfronzo explains this phenomenon to his son, Carlyle― 

Carlyle, my dear son, you remember a time in the past when you came very near drowning. 

As you lost consciousness of your watery surroundings―or was fast becoming oblivious to them, the panorama of your whole life passed like a flash before your mentality, even to the minutest detail—things you supposed long forgotten became clear and distinct.

This was owing to the spirit becoming partly disengaged from the body. 

You were seeing, and remembering, as spirits see and remember, and if you had been wholly disengaged from the body, and your soul had really entered the celestial world, these visions, and this memory, would have been as vivid and bright as the beautiful celestial world is brighter and more vivid than the earthly world.
