始興王第五男蕭曄諮曰。真諦稱真。是實真不。令旨答曰。得是實真。又諮。菩薩會真之時。為忘俗忘真不。令旨答。忘俗忘真。故說會真。又諮。若忘俗忘真故說會真。忘俗忘真何謂實真。令旨答。若存俗存真何謂實真。正由兩遣故謂實真。又諮。若忘俗忘真而是實真。亦應忘真忘俗而是實俗。令旨答。忘俗忘真所以見真。忘真忘俗彌見非俗。又諮。菩薩會真。既忘俗忘真。今呼實真便成乖理。令旨答。假呼實真。終自忘真。兩忘稱實。何謂乖理。

Xiao Ye, the fifth son of the Prince of Shixing, inquired, saying: "When the ultimate truth is called 'true', is it truly true?"
The Prince's decree replied, saying: "It can be considered truly true."
He further inquired: "When a bodhisattva accords with the true, does he forget the conventional and forget the true, or not?"
The decree replied: "Because he forgets the conventional and forgets the true, he is said to accord with the true."
He further inquired: "If he is said to accord with the true because he forgets both the conventional and the true, when both the conventional and the true are forgotten, what can be termed truly true?"
The decree replied: "If the conventional were preserved and the true were preserved, what could be termed truly true? It is precisely because both are relinquished that it is called truly true."
He further inquired: "If forgetting both the conventional and the true is truly true, should not forgetting both the true and the conventional also be truly conventional?"
The decree replied: "Because one forgets the conventional and forgets the true, one perceives the true; as one forgets the true and forgets the conventional, one all the more perceives that it is not conventional."
He further inquired: "When a bodhisattva accords with the true, he already forgets both the conventional and the true; now calling it 'truly true' would contravene the principle."
The decree replied: "Provisionally calling it 'truly true', in the end he himself forgets the true. When both are forgotten it is designated 'true'; how could that contravene the principle?"
