Nature in the Gītā is not scenery. It is the force that makes you act before you decide to. Krishna splits it in two: a lower nature — earth, water, fire, air, space, mind, understanding, and the sense of I — and a higher one, which is life itself, holding the whole world up. You live inside both at once. The lower nature drives every creature to move; even sitting still is nature's doing. The self, watching from within, does nothing at all, though ego insists otherwise. These verses trace that distinction from its first statement to its sharpest consequence. When you see that nature does all the doing and the self merely watches, something loosens. That seeing is what Krishna calls true sight.
