楞伽阿跋多羅寶經註解 2.196

2.196

此四種論，言一向曰直答，謂隨問而答也；反詰問，亦曰反質，謂反質所問也；分別，謂詳辯而答也；止論，謂置而不答也，制諸外道多用止論。有及非有生者，謂數論計有、勝論計無，僧佉者數論也，毘舍者勝論也，如是等法皆無記論所攝。彼外道計不出有無，故云彼如是顯示。以正智觀之，求其性相皆不可得，況言說乎。

Concerning these four kinds of declarations: 'direct' means an immediate answer, which means answering in accordance with the question; 'cross-examination' is also called counter-interrogation, which means questioning back regarding what was asked; 'analytic' means answering with detailed discernment; and 'setting aside' means laying it aside without answering. To overcome the tīrthikas, setting aside is mostly used. 'Arising from existence and nonexistence' means that the Sāṃkhyas assert existence, while the Vaiśeṣikas assert nonexistence; *Sengqie* is Sāṃkhya, and *Pishe* is Vaiśeṣika. Dharmas such as these are all subsumed under inexpressible theses. Those tīrthikas' conceptions do not go beyond existence and nonexistence, hence it says 'thus do they reveal them'. When examined with samyagjñāna, in seeking their nature and characteristics, neither can be found, how much less so verbal expressions?
