二諦義 2.68

2.68

問：若為是正道耶？解云：諸佛不能行、諸佛不能到、諸佛不能說。今作若為說耶？故經云「諸法寂滅相，不可以言宣。」又云「甚深微妙法，唯我知是相，十方佛亦然。」諸大聲聞、不退菩薩皆不能了也。然此始是好。情智二諦，前來三節竝是情謂二諦，離前三節乃是智諦。所以《法華》明如來從三昧安詳而起，歎甚深二智也。

Question: In what way is it the correct Way? Explanation: The Buddhas cannot practice it, the Buddhas cannot reach it, and the Buddhas cannot speak it. How could it now be spoken? Therefore the sūtra says: 'The mark of the quiescence of all dharmas / Cannot be expounded in words.' And it also says: 'This profound, wondrous Dharma— / Only I know its mark, / As do the Buddhas of the ten directions.' Neither the great śrāvakas nor the non-retrogressing bodhisattvas can comprehend it. Yet this is what is truly fine. As for the two truths of sentiment and cognition, the previous three stages are all the two truths of sentimental conception; only departing from the previous three stages is the truth of cognition. This is why the Lotus Sūtra explains that the Tathāgata calmly arose from samādhi and praised the profound two cognitions.
