Quote by Liezi: “Heaven and Earth are only names for the same great entity, the Ultimate Source.”

This quote suggests that the seemingly separate entities of "Heaven" and "Earth" are merely different labels for a single, overarching cosmic principle or origin. It emphasizes the unity of all creation and the existence of a fundamental, interconnected source for everything.

During a period when different philosophical schools debated the nature of reality and the cosmos, Liezi offered a unified vision rooted in Taoist thought, pointing to a singular, ultimate origin underlying all existence.

Taoist philosopher traditionally said to have lived around 400 BCE in the state of Zheng during the Warring States period in China. The text attributed to him, the Liezi, is one of the three foundational texts of philosophical Taoism alongside the Tao Te Ching and the Zhuangzi. Scholars debate whether he was a historical figure or a literary construct.
