It is the home of emotions and of lower thoughts; and emotions are much stronger in that world than in this.

When a person is awake we cannot see that larger part of his emotion at all; its strength goes in setting in motion the gross physical matter of the brain.

So if we see a man show affection here, what we can see is not the whole of his affection, but only such part of it as is left after all this other work has been done.

Emotions therefore bulk far more largely in the astral life than in the physical.

They in no way exclude higher thought if they are controlled, so in the astral world as in the physical a man may devote himself to study and to helping his fellows, or he may waste his time and drift about aimlessly.
The astral world extends nearly to the mean distance of the orbit of the moon; but though the whole of this realm is open to any of its inhabitants who have not permitted the redistribution of their matter, the great majority remain much nearer to the surface of the earth.
