[In the world below...] The wise and orderly soul is conscious of her situation, and follows in the path; but the soul which desires the body, and which... has long been fluttering about the lifeless frame and the world of sight, is after many struggles and many sufferings hardly and with violence carried away by her attendant genius, and when she arrives at the place where the other souls are gathered, if she be impure and have done impure deeds or have been concerned in foul murders or other crimes... from that soul everyone flees and turns away; no one will be her companion, no one her guide, but alone she wanders in extremity of evil until certain times are fulfilled...
