大般涅槃經集解 36.71

36.71

案僧亮曰：答第五難。雖無量名同，內外行異、深淺大殊，不應一也。不能得自在三昧始行菩薩非無量緣者，與父母無量樂，不以無量眾生為緣也。僧宗曰：答第五難。言緣無量眾生為境有四心之別，不言心體通同無際，不可承聲為難也。寶亮曰：答第五難。名字雖同，然義有四階，盡稱無量，不得為一也。

Sengliang states: This answers the fifth objection. Although the name 'immeasurable' is the same, internal and external practices differ, and shallow and deep are greatly distinct; they should not be one. That the initial-stage bodhisattva who cannot attain the samādhi of mastery is not taking the immeasurable as object means that he gives immeasurable bliss to his parents, not taking immeasurable sentient beings as his object. Sengzong states: This answers the fifth objection. It says that taking immeasurable sentient beings as the object has the distinction of four minds; it does not say that the essence of mind is universally boundless; one must not take literal expression to form an objection. Baoliang states: This answers the fifth objection. Although the names are the same, yet the meaning has four stages, all called immeasurable; they cannot be made into one.
