Sattva——from Yoga Sutra

The word sattva comes from the root sat, which means "being" or "truth." It's literally the power of beingness, the inner integrity that let the Buddha sit under the bodhi tree until he became enlightened, the power that supported Gandhi and Martin Luther King Jr., the power that you feel in cathedrals and redwood forests and in people who quietly offer help to those who need it. Sattvic strength is one part discipline and three parts trust—trust that the invisible is stronger than what you can see or touch, and that what you are speaks louder than what you say.
