(kah) is another word with multiple meanings; its most common meanings are "soul" or "vital energy". The ka is the part of us that composes our personality, our self. We feed our ka in life by living in ma'at and receiving praise for others, and rely on our descendants to feed it with offerings when our khat (physical body) dies. The living Heru is believed to have multiple kas, and some Names are considered the ka of other Names (Hatshepsut's throne name was Ma'at-ka-Ra or "Ma'at is Ra's ka").
