Egyptian mythology [SEP] In religion
Because the Egyptians rarely described theological ideas explicitly, the implicit ideas of mythology formed much of the basis for Egyptian religion. The purpose of Egyptian religion was the maintenance of "maat", and the concepts that myths express were believed to be essential to "maat". The rituals of Egyptian religion were meant to make the mythic events, and the concepts they represented, real once more, thereby renewing "maat". The rituals were believed to achieve this effect through the force of "heka", the same connection between the physical and divine realms that enabled the original creation. For this reason, Egyptian rituals often included actions that symbolized mythical events.
