大般涅槃經義記 3.278

3.278

喻中有三：一凡夫有性惑障不見喻、二「有異人」下佛始為說彼聞不見喻、三「即於其家掘出」已下終為開示彼聞悟解喻。初中，「貧女」喻諸凡夫，無德稱貧，能生真解故名為女。五陰為舍，即陰有性，故言「舍內多有金藏」，自己心識名為「家人」，心有麁細利鈍之殊說為「大小」，不覺自身有如來性名「無知者」。亦可二十五有眾生名為家人，人有勝劣名為大小，不同解性名無知者。

Within the simile there are three parts: first, the simile of ordinary beings possessing the nature but not seeing it due to the obstruction of delusions; second, from 'There was a different person' downward, the simile of the Buddha first expounding it for them, but they, upon hearing it, do not see it; third, from 'Immediately in her house dug out' downward, the simile of finally revealing it to them, and they, upon hearing it, awaken and understand. In the first part, the 'poor woman' is a simile for ordinary beings; having no virtues, she is called poor, but being able to give birth to true understanding, she is called a woman. The five aggregates are the house, and right within the aggregates there is the nature; hence it says, 'Inside the house there was much gold stored.' One's own mind-consciousness is called 'family members.' The mind has differences of coarse and subtle, sharp and dull, which are described as 'great and small.' Not being aware that one's own body possesses the tathāgata-nature is called 'unknowing.' Alternatively, the sentient beings of the twenty-five states of existence are called family members, people having superior and inferior qualities are called great and small, and failing to understand the nature is called unknowing.
