How Differentiation in Feldenkrais 'Works'

Generally, Feldenkraisers avoid the word 'work' because the real learning happens in the easy zone. But if 'work' means 'good function,' then ok. We're in: Feldenkrais gives ease, pleasure, range of motion, efficiency and something harder to pin down: a sense of greater coordination, less effort, more options. So when we say differentiation 'works,' we mean: it improves awareness and movement in ways the organism can feel and use.
