Masu's "Beyond the Hundred Negations"

A monk asked Master Masu, " Does a dog have Buddha-nature or not?" Masu replied, "It does not." The monk then asked, "All sentient beings have Buddha-nature. Why does the dog not have it?" Masu answered, "Because it has karmic consciousness." Later, a monk asked Master Joshu the same question. Joshu answered, "It does not." Hearing of this, Masu remarked, "Joshu has gone beyond the hundred negations."
