大般涅槃經義記 9.244

9.244

「若說」已下是第三句以內類外破他救義。他人救言：「從外四大增內四大」，故內有性。「不見從內增外四大」，故外無性。故今舉內類同於外，明內四大亦有不藉外大增長，應先無性。即事顯之，「如尸利沙果先無形質，見昴星時果則出生足長五寸。如是果者實不因於外四大增」，亦應同外先無自性。

From "if it is said" onwards is the third phrase, using the internal to analogize the external to refute the other's defense. The other party defends by saying: "The internal four great elements increase from the external four great elements," therefore the internal has a nature; "one does not see the external four great elements increase from the internal," therefore the external lacks a nature. Therefore, the text now brings up the internal to liken it to the external, clarifying that the internal four great elements also can increase without relying on the external elements, and so should likewise lack prior nature. Demonstrating this through actual phenomena: "Just as the śirīṣa fruit originally has no physical form, but when the Pleiades (Kṛttikā) are seen, the fruit then appears and grows to a full five inches. Such a fruit does indeed not depend on the increase of the external four great elements"—it should likewise, like the external, lack prior self-nature.
