Compassion means more than simply being kind.
Compassion—or active compassion—is how we usually translate bodhicitta or changchub sem.
Compassion includes kindness, but kindness is but part of the spectrum of compassion.
Compassion includes appreciation, admiration, pleasure, wonder, enjoyment, and communication—fierce, florid, and fecund communication.
Compassion is openness to infinite pattern and to embodying any aspect of that pattern for the benefit of everyone, and everything, everywhere.
