On Compassion and Equanimity

During my time studying Buddhism in the jungle district of Alawwa, I came across this powerful quote by the Ven. Nyanaponika Mahathera:

“Compassion guards equanimity from falling into a cold indifference, and keeps it from indolent or selfish isolation. Until equanimity has reached perfection, compassion urges it to enter again and again the battles of the world, in order to be able to stand the test, by hardening and strengthening itself. Equanimity furnishes compassion with an even, unwavering courage and fearlessness, enabling it to face the awesome abyss of misery and despair which confront boundless compassion again and again. To the active side of compassion, equanimity is the calm and firm hand led by wisdom – indispensable to those who want to practice the difficult art of helping others.”
