According to Stephen Gilligan, compassion has three energies or faces:
Tenderness in the face of pain;
Fierceness in the face of injustice;
Mischievousness in the face of resistance.
I especially like the addition of the third face because it makes me smile, but also because it's clear that creativity is needed to fully live compassionately.
