To enable a person to clearly hand over the thought (spirit) that he/she wants to hand over or his/her actual image to posterity, whereas people believe that the spirits will be left although it is impossible to desire a permanent life, and has practiced to bury the dead body or ashes in a grave and worship a mortuary tablet with the posthumous Buddhist name written thereon in a family Buddhist altar since ancient times and, further, a portrait, bronze statue, picture, video or the like can be left to remember the deceased, but since it is selectively left by the bereaved or descendant, the thought (spirit) or real image cannot be handed over and extinguished with time.

A registered person provides information for the own thought (spirit) of image that he/she wants to hand down to posterity to a management corporation (manager) in life, the manager registers the information in a computer server and further enters it in a DVD software or the like. The DVD software or the like is worshiped as grave, family Buddhist altar or mortuary tablet itself because the registered person's thought (spirit) is entered. The information of the registered person can be clearly and permanently handed over by this computer system and management system.
