The purpose of claiming souls is to play with them. To experience their feelings. To have the material existence of a body. To sense the world. To understand, explore, dominate. There are as many reasons for claiming a soul as there are different mentalities, and different souls. The mentality itself cannot experience joy or sadness. It cannot taste anything. It has no tingling skin or sexual desires. But all these phenomenons is accessible for the mentality, when it is part of a soul.
