Diamond Sutra
Chapter 31
The Lord Buddha addressed Subhuti, saying: “If a disciple affirmed that the Lord Buddha enunciated a belief that the mind can comprehend the idea of an entity, a being, a living being, or a personality; what think you, Subhuti, would that disciple be interpreting aright the meaning of my discourse?” Subhuti replied, saying: “Honoured of the Worlds! that disciple would not be interpreting aright the meaning of the Lord Buddha’s discourse. And why? Because, Honoured of the Worlds! discoursing upon comprehending such ideas as an entity, a being, a living being, and a personality, it was declared that these are entirely unreal and illusive, and therefore they are merely termed an entity, a being, a living being, and a personality.”
The Lord Buddha thereafter addressed Subhuti, saying: “Those who aspire to the attainment of supreme spiritual wisdom ought thus to know, believe in, and interpret phenomena. They ought to eliminate from their minds every tangible evidence of every visible object. Subhuti, concerning ‘visible objects,’ the Lord Buddha declared that these are not really ‘visible objects’ they are merely termed ‘visible objects.’”
