The spirits that are desperately attached to this plane, and especially those among them that have but lately left it, manifest to the view as apparitions, or else by knocking at the door, by rapping on the tables and chairs, by lifting and removing objects, and by speaking. Their voices vibrate in the spheres and become audible to some of us. Sometimes one hears singing and shouting, and sometimes dancing on the top floor, or fighting going on among them. Some spirits appear to the living without any clothes, some with their legs and feet twisted outward. The former is owing to their lust, also to the misery they went through in life; the latter is due to a life passed in the thought of duality, and because they have gone astray in life, not having kept to the thought of unity; their body itself then demonstrates their crookedness.
