Dualism knows by comparison, opposition, and differentiation. It uses descriptive words like good/evil, pretty/ugly, smart/stupid, not realizing there may be a hundred degrees between the two ends of each spectrum. We do need the dualistic mind to function in practical life; to do our work as a teacher, a nurse, a scientist, or an engineer. It’s helpful and fully necessary as far as it goes, but it just doesn’t go far enough. Dualistic thinking works well for the sake of simplification and conversation, but not for the sake of truth or the immense subtlety of actual personal experience. The dualistic mind cannot process things like infinity, mystery, God, grace, suffering, sexuality, death, or love; this is exactly why most people stumble over these very issues. The dualistic mind pulls everything down into some kind of tit-for-tat system of false choices and too-simple contraries, which is largely what “fast food religion” teaches, usually without even knowing it. Without the contemplative and converted mind –an honest and humble perception– much religion is frankly dangerous. Most of us settle for quick and easy answers instead of any deep perception, which we leave to poets, philosophers, and prophets. Yet depth and breadth of perception should be the primary arena for all authentic religion. How else could we possibly search for God?
