From this fine Brainpickings article, When Things Fall Apart: Tibetan Buddhist Nun and Teacher Pema Chödrön on Transformation Through Difficult Times
To stay with that shakiness — to stay with a broken heart, with a rumbling stomach, with the feeling of hopelessness and wanting to get revenge — that is the path of true awakening. Sticking with that uncertainty, getting the knack of relaxing in the midst of chaos, learning not to panic — this is the spiritual path. Getting the knack of catching ourselves, of gently and compassionately catching ourselves, is the path of the warrior. We catch ourselves one zillion times as once again, whether we like it or not, we harden into resentment, bitterness, righteous indignation — harden in any way, even into a sense of relief, a sense of inspiration.
