"Bhikkhus, when the uninstructed worldling is being contacted by a painful feeling, he sorrows, grieves, and laments.... He feels two feelings — a bodily one and a mental one. Suppose they were to strike a man with a dart, and then they would strike him immediately afterwards with a second dart, so that the man would feel a feeling caused by two darts.... Bhikkhus, when the instructed noble disciple is contacted by a painful feeling, he does not sorrow, grieve, or lament; he does not weep beating his breast and become distraught. He feels one feeling — a bodily one, not a mental one" (SN 36.6).
