Diamond Sutra
Chapter 21
The Lord Buddha addressed Subhuti, saying: “Do not affirm that the Lord Buddha thinks thus within himself, ‘I ought to promulgate a system of Law or doctrine.’ Have no such irrelevant thought! And why? Because, if a disciple affirmed that the Lord Buddha promulgated a system of Law or doctrine, he would defame the Lord Buddha, being manifestly unable to understand the purport of my instruction. Subhuti, regarding the promulgation of a ‘system of Law or doctrine,’ there is in reality no ‘system of Law or doctrine’ to promulgate, it is merely termed a ‘system of Law or doctrine.’”
Upon that occasion, the virtuous and venerable Subhuti enquired of the Lord Buddha, saying: “Honoured of the Worlds! in ages to come, will sentient beings destined to hear this Law, engender within their minds the essential elements of faith?” The Lord Buddha replied, saying: “Subhuti, it cannot be asserted that these are sentient beings, or that these are not sentient beings. And why? Because, Subhuti, regarding ‘sentient beings,’ the Lord Buddha declared that in reality these are not ‘sentient beings,’ they are merely termed ‘sentient beings.’”
