Ka is a concept from ancient Egyptian mythology that represents the vital essence or life force of a person. It is believed to be a spiritual double that exists alongside the physical body, continuing to live on after death. The Ka is often depicted in tomb art, where it is shown receiving offerings to sustain it in the afterlife. In ancient Egyptian culture, the Ka was crucial for ensuring a person's immortality. Rituals and funerary practices were designed to honor and nourish the Ka, allowing it to thrive in the realm of the dead. This belief underscores the importance of the afterlife in Egyptian spirituality and the care taken in burial practices.
