What is the purpose of a Ka statue in ancient Egyptian culture?

The purpose of a Ka statue in ancient Egyptian culture is to serve as the resting place for a person's life force, known as the "Ka." In ancient Egyptian belief, the Ka was considered an essential aspect of a person's existence that continued on after death. Creating a Ka statue would provide the deceased with a physical form to inhabit in the afterlife, ensuring that their spirit had a home within the tomb. This belief highlights the importance of the afterlife in Egyptian culture and the role of statues in facilitating a connection between the living and the spiritual world.

The other options do not encompass the primary role of the Ka statue. Decorative pieces in tombs might serve aesthetic purposes, but they do not carry the same spiritual significance as Ka statues. Similarly, while a statue could represent a deity or commemorate significant life events, these functions are not the core purpose of the Ka statue. Instead, it uniquely signifies the spiritual needs associated with the individual's afterlife journey.
