The Ancient Egyptians believe the human soul has five divisions or components. They named them Ren, Ka, Ib, Ba, and Sheut.
Ren is literally your name. It lives as long as you are remembered, or read about by others, or prayed to as an ancestor.
Ka is the vital essence that makes the difference between the living and the dead. It animates your body keeping your corporeal existence intact.
Ib is literally the heart. It is formed from a single drop of blood from your mother’s heart. It is the seat of your soul and considered the good directing force in your life. It searches for truth and peace.
Ba makes us all different, a unique individual. It motivates us to achieve our goals. It is a hungry elemental force that creates desire for food and sex. Ba will survive after death. It may go forth by day to enjoy the light, or it may end up a creature of darkness in eternal night.
Sheut is your shadow self. It is the other you that many people never realize exists. It travels on the astral plane while you sleep or meditate. It can move very quickly.
