Four myths about Zen Buddhism’s “Mu Koan”
By Steven Heine
The Mu Koan (or Wu Gongan in Chinese pronunciation), in which master Joshu says “Mu” (literally “No,” but implying Nothingness) to an anonymous monk’s question of whether a dog has the Buddha-nature, is surely the single most famous expression in Zen Buddhist literature and practice. By virtue of its simplicity and indirection, this expression becomes emblematic of East Asian spirituality and culture more generally. Entire books have been published on the topic on both sides of the Pacific.
