Part Two: Section 3. Questions and answers on the soul
Is the soul always with the person during his lifetime, or can it leave him temporarily, even making its home elsewhere?
As a rule, the soul always remains with the person during his lifetime, but it can leave the body for a few minutes, or a few hours at most, while the person is asleep. It can also leave the body for a short period while the aspirant is in a deep state of meditation. Then one can see one's own body. One may see it as a dead body or a dynamic body or as a shaft of light facing his soul, or in many other ways. Of course, at that time, one sees the body with the eye of his own soul.
