In the Beginningless Beginning, there was Ame no Minaka-nushi no Kami, the Ruling Spirit of the Center of Creation, and Absolutely Nothing Else At All.

Absolutely Nothing Else At All faced the outside of the Center of Creation, where Ame no Minakanushi no Kami dwelt, and spontaneously, simultaneously, reacted to the Divine Virtue by on the one hand expanding it to fill the Endless Emptiness and create Heaven, becoming Takamimusubi no Kami, the “Exalted Creator Spirit”; on the other, reflecting and compressing and digesting the Divine Virtue, forming the Earth and becoming Kamimusubi no Kami, the “Divine Creator Spirit”.

This was quite a while ago, obviously.
