Is this what we call being apathetic person (see quote below), having a heart of stone and where everything is just the same color ...?
"Feelings are just feelings, happiness is just happiness, suffering is just suffering.
Only that. Having arisen, it all ceases. We don’t have happiness and suffering. We
don’t take interest in them. They are just attributes of the mental objects that come up
– just that much. The lokadhamma¯ appear and vanish according to their own logic.
Finally, if we don’t show interest in them, don’t support and give importance to them,
they lose their existence".
