論。當知過去至得成淨信　釋曰。此顯僧寶依法而成。夫言僧者和合為義。淨信無適方得名僧。三世菩薩既依此法得成淨信。故謗此法亦得名為斷三寶種。由有法故佛僧不斷。故佛僧斷由法不行。故雖但舉佛僧二寶。亦顯法寶斷不斷義。

Treatise: "One should know that past [bodhisattvas relied on this Dharma] … to attain the accomplishment of pure faith." / Commentary: This reveals that the Saṅgha Jewel is accomplished by relying on the Dharma. Now, as for the term "Saṅgha", its meaning is harmony. Only when pure faith is without blemish can it be called a saṅgha. Since the bodhisattvas of the three periods of time have attained the accomplishment of pure faith by relying on this Dharma, slandering this Dharma can therefore also be called severing the lineage of the Three Jewels. Because there is the Dharma, the Buddha and Saṅgha are not interrupted; therefore, the interruption of the Buddha and Saṅgha is due to the Dharma not being practiced. Thus, although it mentions only the two jewels of the Buddha and the Saṅgha, it also reveals the meaning of the Dharma Jewel being severed or not severed.
