《论衡·卷二十·论死篇》
磷，是死人的血，它的形状不同于活人的形体。它的形状不像活人的形体，那么精气离开了人体后，为什么会像活人的形体呢？
磷，死人之血也，其形不类生人之血也，其形不类生人之形。精气去人，何故象人之体？
Phosphorus is the blood of the dead, and its shape is different from that of the living. Its shape is unlike that of the living, so why does the vital essence look like a living person after leaving the body?
