Answer:
In order to live for all eternity and be presented in front of Osiris, the body of the deceased had to be preserved by mummification, so that the soul could reunite with it, and take pleasure in the afterlife.
Mummification is the process of preserving the body after death by deliberately drying or embalming flesh. This typically involved removing moisture from a deceased body and using chemicals or natural preservatives, such as resin, to desiccate the flesh and organs.
