大般涅槃經集解 54.161

54.161

案道生曰：向明十二因緣觀智，該取因時名為佛性，故以胡苽為譬。真見因緣然後果成者，非其譬矣。僧亮曰：上說因為種子，是謂種性相生也；今說種子為性，是因中說果，所以為異耳。寶亮曰：為上二因作譬也。雖復非佛，以能得佛果，故名佛性。

Daosheng comments: Above, it clarified that the contemplative wisdom of the twelve links of dependent origination embraces and takes the causal time as being called buddhadhātu; therefore the cucumber is used as a metaphor. If the effect were completed only after truly seeing causes and conditions, it would not serve as its metaphor. Sengliang comments: Above spoke of the cause as seed, which is the mutual arising of seed and nature; here it speaks of the seed as nature, which is speaking of the effect in the cause, hence the difference. Baoliang comments: This creates a metaphor for the two causes above. Although it is not yet the Buddha, because it can obtain the Buddha effect, it is called buddhadhātu.
