問。如上所說。芥納須彌。毛吞巨海。既唯一心。須彌為復入芥子。不入芥子。若言入。經何故云。須彌本相如故。若言不入。又云。唯應度者見之。

Question: As explained above, a mustard seed contains Mount Sumeru, and a hair-tip swallows the great ocean; since there is only the one mind, does Sumeru actually enter the mustard seed, or does it not enter the mustard seed? If you say it enters, why does the sūtra say: 'The original characteristic of Mount Sumeru remains as it was'? If you say it does not enter, it is also said: 'Only those who are to be saved can see it.'
