Abstract

Emptiness in India has a subtly different flavor from emptiness in China, inflected as the latter had been with a metaphysical framework inherited from the Daoist and Confucian traditions. The Huayan tradition universalizes the idea of interdependence. According to philosophers in this tradition, it is not merely that everything depends upon some other things, but that everything depends upon all other things, and that each phenomenon interpenetrates every other phenomenon. The Net of Indra is a dominant metaphor of Huayan Buddhism, but its exact content is somewhat obscure. Drawing on a graph-theoretic representation of the key notion of emptiness, this chapter delivers a precise account of the metaphor, showing how it does justice to core Huayan views. It demonstrates the utility of contemporary logical-mathematical tools for making precise classical Buddhist doctrines, and for defusing suspicions of mystical incoherence.
