twofold_truth　二諦 The two dimensions of śūnyatā, emptiness, the ultimate reality clarified by Nāgārjuna and regarded as the core of Mahayana philosophy. The ultimate reality is beyond human conceptual understanding, and yet it is made conceivable by conceptual understanding. See ‘body of true reality, body for the sake of beings’, ‘dharma-bodies of two dimensions’, ‘dharma-body of equality’, and ‘extensive and brief’.
