3.178

九折之二也。徵，責也。前章云：涅槃之道果出有無之境。徵意云：有無二法攝盡一切，如何有無之外別有涅槃之體？今詳徵辭，包舉儒老有無之說，復引小乘有無二為例以徵之。下超境中皆超此有無。

This is the second of the nine dialectical shifts. 'Challenge' (zheng) means to cross-examine. The preceding chapter stated that the path of nirvāṇa indeed transcends the realms of existence and non-existence. The intention of the challenge is: the two dharmas of existence and non-existence encompass everything; how could there be a separate substance of nirvāṇa outside of existence and non-existence? Examining the words of the challenge now, it includes the doctrines of existence and non-existence of Confucianism and Laozi, and further cites the two dharmas of existence and non-existence of the Hīnayāna as examples to challenge it. The 'transcendence of the realm' below completely transcends this existence and non-existence.
