“There was something undifferentiated and yet complete, which existed before Heaven and Earth. Soundless and formless, it depends on nothing and does not change. It operates everywhere and is free from danger. It may be considered the mother of the universe. I do not know its name; I call it Tao.”

Lao Tzu is a 6th-century BCE Chinese philosopher and writer. He is best known as the traditional author of the *Tao Te Ching*, a foundational text of Taoist thought that explores simplicity, natural harmony, and the virtue of *wu wei* (non-action). His teachings emphasize living in alignment with the Tao, or the natural way of the universe.
