According to Maranaw folklore, this world was created by a great Being in an unknown number of days. It is divided into seven layers - the uppermost layer is inhabited by humans, the second by dwarfs, and the third under seas and lakes by nymphs. The sky also has seven layers guarded by huge birds and inhabited by angels in each layer. Heaven, on the seventh layer of the sky, is where good people's spirits go after death and where a tree of life tracks the lives of people on earth through leaves with their names. Souls are kept in jars in heaven guarded by a monster with a thousand eyes.
