When a wealthy man died, fearing that their property would be confiscated, the funeral was held up until the family donated a large sum to public welfare or to the king, an inheritance tax.  Egyptians believed preservation of body facilitated passage through future life. 
Almost every group had a different idea regarding the destiny of the ghost soul. The Chinese and Egyptians once believed that soul and body remained together. Among the Egyptians this led to careful tomb construction and efforts at body preservation. Even modern peoples seek to arrest the decay of the dead. 
Ancient funeral wastes were enormous. Modern man is not supposed to fear ghosts, but custom is strong, and much terrestrial wealth is still consumed on funeral rituals and death ceremonies.  Religion has unduly impoverished life for the pretended enrichment of death.  On worlds settled in light and life, “funerals” are occasions of supreme joy, profound satisfaction, and inexpressible hope.
