The people of ancient Egypt enjoyed life and wanted all of the things that made them happy on earth in the afterlife. They believed that every person had a Ka (the life force created at birth and released by death) and a Ba (like the soul). In order to live forever, the Ka and the Ba had to be reunited after death. This is why it was important to preserve the body after a person died.
Not everyone was mummified. Poor people's bodies were buried in the desert where the sand dried their bodies. Food, tools, and jewelry were laid beside them for use in the afterlife. Wealthy people could afford to have their bodies mummified and placed with their possessions in tombs. The coffins were enclosed in large stone boxes, or sarcophagi, to protect them from tomb robbers or attacks from hungry wild animals.
Mummification is the process of slowly drying a dead body to stop it from rotting. In ancient Egypt, the process took about 70 days. Embalming priests removed the liver, lungs, stomach, and intestines and stored them in four special little coffins called canopic jars. Later, these were placed in the tomb beside the mummy. The priests also removed the brain, but left the heart to be weighed by the god Anubis. They washed the body in palm wine and covered it with a natural salt called natron to absorb the moisture. After 40 days, embalmers rubbed the skin with oils, packed the body with spices, linen, sawdust, and sand to reshape it, and wrapped it in layers of linen bandages that had been soaked in resin. They placed magic spells and good luck charms between the strips. Finally, they sealed the mummy in its case.
