Diamond Sutra
Chapter 26
The Lord Buddha addressed Subhuti, saying: “Can the Lord Buddha be perceived by means of his thirty-two bodily distinctions?” Subhuti replied, saying: “Even so, the Lord Buddha can be perceived by means of his thirty-two bodily distinctions.”
The Lord Buddha, continuing, said unto Subhuti: “If by means of his thirty-two bodily distinctions it were possible to perceive the Lord Buddha, then the Lord Buddha would merely resemble one of the great wheel-turning kings.”
Subhuti thereupon addressed the Lord Buddha, saying: “Honoured of the Worlds! According as I am able to interpret the Lord Buddha’s instruction, it is improbable that the Lord Buddha may be perceived by means of his thirty-two bodily distinctions.”
