Buddha in your heart is a symbol of faith: you could be immaculate and perfect, as perfect as Shakyamuni Buddha himself. That possibility already exists in you. . . . In this case, faith has nothing to do with praying to somebody. Faith is a sense of dignity. The Christian mystic Meister Eckhart talks about faith in the sense of being awake: being present and mindful and aware of the situation. Faith is seeing things as they are—whatever that might be—precisely, directly, and without any hesitation.
