妙法蓮華經玄義 8.77

8.77

《大經》云：「一實諦者，則無有二，無有二故名一實諦；又、一實諦名無虛偽；又、一實諦無有顛倒；又、一實諦非魔所說；又、一實諦名常樂我淨。」常、樂、我、淨，無空、假、中之異。異則為二，二故非一實諦；一實諦即空即假即中，無異無二，故名一實諦。若有三異，則為虛偽，虛偽之法，不名一實諦；無三異故，即一實諦。若異即是顛倒未破，非一實諦；無三異故無顛倒，無顛倒故名一實諦。異者，不名一乘；三法不異，具足圓滿，名為一乘。是乘高廣，眾寶莊挍，故名一實諦。

The Mahāparinirvāṇa-sūtra says: 'The single real truth is without duality; because it is without duality, it is called the single real truth. Furthermore, the single real truth is named without falsehood; furthermore, the single real truth is without inversion; furthermore, the single real truth is not spoken by Māra; furthermore, the single real truth is called permanence, bliss, self, and purity.' Permanence, bliss, self, and purity are without the differences of emptiness, provisionality, and the middle. If there were differences, they would be dual; being dual, they would not be the single real truth. The single real truth is identical to emptiness, identical to the provisional, and identical to the middle, without difference and without duality, and is therefore called the single real truth. If there were three differences, it would be false; a false dharma is not called the single real truth; because there are no three differences, it is the single real truth. If there were differences, then inversions would not yet be destroyed, and it would not be the single real truth; because there are no three differences, there are no inversions, and because there are no inversions, it is called the single real truth. What has differences is not called the single vehicle; when the three dharmas are not different and are fully complete and perfect, it is called the single vehicle. This vehicle is high and broad, adorned with many jewels, and is therefore called the single real truth.
