Diamond Sutra
Chapter 20
The Lord Buddha addressed Subhuti, saying: “What think you? Can the Lord Buddha be perceived by means of his perfect material body?” Subhuti replied, saying: “Honoured of the Worlds! it is improbable that the Lord Buddha can be perceived by means of his perfect material body. And why? Because, what the Lord Buddha referred to as a ‘perfect material body,’ is not in reality a ‘perfect material body,’ it is merely termed a ‘perfect material body.’”
