Vagrakkhedikâ (Diamond-cutter), section 23

‘Also, Subhuti, all is the same there, there is no difference there, and therefore it is called the highest perfect knowledge. Free from self, free from being, free from life, free from personality, that highest perfect knowledge is always the same, and thus known with all good things. And why? Because, what were preached as good things, good things indeed, O Subhuti, they were preached as no-things by the Tathagata, and therefore they are called good things.’ (23)
