I don't think there is anything as powerful as an active heart. They do not fear the wisdom of emotion, but embody it. They know how to listen. They are polite when they need to be and unyielding when necessary. They remain open, even as they push boundaries and inhabit the margins, understanding eventually, the margins will move toward the center. They are tenacious, informed, patient, and impatient, at once. They do not shy away from what is difficult. They refuse to accept the unacceptable. The most effective activists I know are in love with the world.
