三无差（三无差别）
The three that are without (essential) difference, i.e. are of the same nature: (a) 心 The nature of mind is the same in Buddhas, and men, and all the living; (b) 佛 the nature and enlightenment of all Buddhas is the same; (c) 生 the nature and enlightenment of all the living is the same. The 华严经 says 心佛及生, 是三无差别.
