“Bhikkhus, when the uninstructed worldling makes the statement, ‘In the great ocean there is a bottomless abyss,’ he makes such a statement about something that is nonexistent and unreal. This, bhikkhus, is rather a designation for painful bodily feelings, that is, ‘bottomless abyss.’
“When the uninstructed worldling is contacted by a painful bodily feeling, he sorrows, grieves, and laments; he weeps and beats his breast and becomes distraught. This is called an uninstructed worldling who has not risen up in the bottomless abyss, one who has not gained a foothold.
“But, bhikkhus, when the instructed noble disciple is contacted by a painful bodily feeling, he does not sorrow, grieve, or lament; he does not weep and beat his breast and become distraught. This is called an instructed noble disciple who has risen up in the bottomless abyss, one who has gained a foothold.”
One who cannot endure
The arisen painful feelings,
Bodily feelings that sap one’s life,
Who trembles when they touch him,
A weakling of little strength
Who weeps out loud and wails:
He has not risen up in the bottomless abyss,
Nor has he even gained a foothold. sn.iv.207But one who is able to endure them—
The arisen painful feelings,
Bodily feelings that sap one’s life—
Who trembles not when they touch him:
He has risen up in the bottomless abyss,
And he has also gained a foothold.
