The document tells a story about a rich merchant who had four wives. When he fell ill and knew he was dying, he asked each wife to stay with him after death. The 4th, 3rd and 2nd wives all refused. Only the 1st wife, who he had neglected, agreed to stay with him. It then provides an analogy - that in our own lives we have four "wives" - our body, status/wealth, family/friends, and soul. Only our soul will stay with us after death, so we should focus on cultivating our soul while alive rather than neglecting it.
