Karuṇā: Compassion
Compassion is the heart's shaking at another's pain. Moses has just been offered a nation of his own in place of these people, and he turns back toward the crowd that was ready to stone him an hour earlier. Like a parent still pleading for a child who has disgraced them in front of everyone, he puts himself where the blow would land and asks that it stop.
Accaya: Transgression seen as transgression
Accaya is a fault named openly by the one who owns it. "The iniquity of this people" comes with no excuse attached about the giants, the desert, or the fear; the wrong is set on the table as a wrong. Pardon has something to take hold of only once the thing is in plain sight, the way a debt has to be stated in figures before anyone can cancel it.
Mettā: Loving kindness
Mettā is goodwill with no conditions on it. The plea skips past the people's merits, which are spent, and leans its whole weight on a kindness whose only measure is its own greatness. Warmth of that size works the way sunlight does over a field, falling on the crop and the weeds without sorting them first.
Khanti: Patient endurance
Khanti is the strength to bear provocation without hardening. "From Egypt even until now" gathers the whole string of them: the bitter water, the golden calf, the crying for meat, and now the panic at the border. Moses builds his request on that long record, trusting that patience stretched this far will stretch once more.
Kamma: Action and its fruit
Kamma is deed ripening into result. Pardon arrives in the next breath, and still not one of that generation walks into the land; the bond is mended while the consequence goes on unfolding. Forgiveness settles what stands between two parties, the way a child is forgiven for the broken window and the window still has to be replaced.
