Seen in its own right, a spiritual inner self is an angel of heaven, and while it is living in the body it is also in the company of angels even though it is not aware of being so; and once it is released from the body it joins them. A merely earthly inner self, though, when seen in its own right, is not an angel but a spirit and is also in the company of spirits while it is living in the body. However, it is with spirits who are in hell, and after its release from the body it joins them.
The deeper levels of [the minds of] people who are spiritual are actively raised up toward heaven because that is their primary focus, while the deeper levels of the minds of people who are merely earthly are actively turned toward this world because that is their primary focus. For all of us, our inner levels, which are levels of our higher mind, are turned toward what we love above all, and our outer levels, which are levels of our lower mind, are turned in the same direction as the inner.
