Mother Earth is the spirit of the Earth. Amaterasu is the spirit of the Sun, that is, the feminine aspect of the spirit of the Sun. The Sun is a male, but everything is polarized, everything has a male and a female part. And she is the feminine part of light. Relative to the Earth it is more of a male energy, but she is the energy that comes and moves through Mother Earth, to bring consciousness and life.
