"Visākhā, those who have a hundred dear ones have a hundred sufferings. Those who have ninety dear ones have ninety sufferings. Those who have eighty... seventy... sixty... fifty... forty... thirty... twenty... ten... nine... eight... seven... six... five... four... three... two... Those who have one dear one have one suffering. Those who have no dear ones have no sufferings. They are free from sorrow, free from stain, free from lamentation, I tell you."
Then, on realizing the significance of that, the Blessed One on that occasion exclaimed:
The sorrows, lamentations,
the many kinds of suffering in the world,
exist dependent on something dear.
They don't exist
when there's nothing dear.
And thus blissful & sorrowless
are those for whom nothing
in the world is anywhere dear.
So one who aspires
to the stainless & sorrowless
shouldn't make anything dear
in the world
anywhere.
