The Discourse on Matter
65.
"Monks, there are these four persons existing and found in the world.
Which four?
One who measures by appearance and is pleased by appearance, one who measures by sound and is pleased by sound, one who measures by austerity and is pleased by austerity, one who measures by the teaching and is pleased by the teaching -
these, monks, are the four persons existing and found in the world."
"Those who measured by appearance, and those who followed by sound;
Overcome by the power of desire and lust, those people do not directly know.
"He does not know internally, and he does not see externally;
The fool obstructed all around, he indeed is carried away by sound.
"He does not know internally, but he sees with insight externally;
Seeing the fruit externally, he too is carried away by sound.
"He understands internally, and he sees with insight externally;
One who sees with obstructions removed, he is not carried away by sound." The fifth.
