The term 'Eternally Nameless Thing' can be summed up by the three-letter acronym TAO. Tao is a Chinese philosophical concept that refers to the fundamental nature of the universe and its power. It is often described as the source of all existence, and is seen as an eternal, nameless thing that cannot be fully understood or explained. Taoism is a religion based on this concept, and it emphasizes living in harmony with the Tao.
