金光明最勝王經疏 3.109

3.109

贊曰：成前中道。法體如如，法身是解脫生死之處，即是解脫。過死生境，出有漏果，離苦諦、越生死闇，離苦諦因、斷集諦，故是中道。

Commentary: This establishes the aforementioned Middle Way. 'The substance of things is tathatā': the dharmakāya is the place where birth and death are liberated, which is liberation itself. 'Transcending the realm of death and birth': emerging from the contaminated fruit, departing from the truth of suffering (duḥkhasatya). 'Going beyond the darkness of saṃsāra': departing from the cause of the truth of suffering and severing the truth of origination (samudayasatya). Therefore, it is the Middle Way.
