 It is proposed, instead, that perhaps a partless entity may be extended in space, and so perceived. But perception is generated by contact between a sensory organ and its object. This requires the object to put up some kind of resistance. But if a thing has no parts, then its near side is its far side, which means that to be adjacent to it is to have passed it by. Partless atoms are therefore logically incapable of providing the resistance that is definitive of physicality and the basis for sensory contact (Vasubandhu says that they cannot produce light on one side and shade on the other). This confirms that entities must be combined into larger groupings in order to be functional and perceptible, which has already been shown impossible.
