This article investigates a central yet perplexing term yiming in the ‘Qiwulun’ chapter of the Zhuangzi. Yiming describes a crucial way to detach from epistemic distinctions and debates. This term is often explained as ‘using ming’ or contradictorily as ‘stopping ming’. Yet neither of the two explanations can provide a full understanding of how yiming is adopted. I take three steps to explain yiming. First, taking an etymological approach, I argue that ming can be formulated as (...) ‘X shining on Y’. Second, I use the formula of ‘X shining on Y’ to account for yiming and argue that this term refers specifically to ‘using tian to shine on everything’. Third, I unpack a cluster of tian-associated metaphors, which provides a deep understanding of yiming as an ideal way to mental tranquility. (shrink)
