大般涅槃經集解 8.20

8.20

案僧亮曰：羅漢心者，少欲知足也。以此二緣者，聲聞不具上三事，菩薩具三事也。曇濟曰：以此二緣者，一以聲聞無眷屬、二以菩薩多眷屬也。僧宗曰：二因緣者，一謂善能問答，現在有益；二以令久住，未來有益也。慧誕曰：二緣者，一以能問、二以能說。明駿案：二緣者，一者能令法寶久住、二者利安眾生也。

Sengliang comments: "The mind of an arhat" means few desires and knowing contentment. "Because of these two conditions": śrāvakas lack the above three things, whereas bodhisattvas possess the three things. Tanji says: "Because of these two conditions": first, because śrāvakas have no retinue; second, because bodhisattvas have many retinues. Sengzong says: The two causes and conditions are: first, being skilled in asking and answering, which brings benefit in the present; second, causing [the Dharma] to abide long, which brings benefit in the future. Huidan says: The two conditions are: first, being able to ask; second, being able to speak. Mingjun comments: The two conditions are: first, being able to cause the Dharma-jewel to abide long; second, benefiting and giving peace to sentient beings.
