妙法蓮華經玄義 5.24

5.24

二次引眾經，明位數多少者，《大涅槃》云：「月愛三昧，從初一日至十五日，光色漸漸增長。又從十六日至三十日，光色漸漸損減。」光色增長，譬十五智德，摩訶般若。光色漸減，譬十五斷德，無累解脫。三十心為三智斷，十地為十智斷，等覺、妙覺各為一智斷，合十五智斷，月體譬法身。《大經》云：「月性常圓，實無增減。」因須彌山，故有虧盈。不增而增，白月漸著；不減而減，黑月稍無。法身亦爾，實無智斷，因無明故，約如論智，如實不智；約如論斷，如實不斷。雖無智而智，般若漸漸明；雖無斷而斷，解脫漸漸離。舉月為喻，知是圓教智斷位也。《大經》云：「從初安置諸子祕密之藏，三德涅槃，然後我當於此祕藏而般涅槃。」此即最後智斷也。

Second, citing various sūtras to clarify the number of stages: The Mahā-parinirvāṇa says, 'The moon-loving samādhi, from the first day to the fifteenth day, gradually increases in light and colour; furthermore, from the sixteenth day to the thirtieth day, it gradually decreases in light and colour.' The increase in light and colour exemplifies the fifteen virtues of wisdom, mahā-prajñā. The gradual decrease in light and colour exemplifies the fifteen virtues of severance, untrammelled liberation. The thirty minds are three instances of wisdom and severance, the ten grounds are ten instances of wisdom and severance, and virtual enlightenment and wondrous enlightenment are each one instance of wisdom and severance, totaling fifteen instances of wisdom and severance. The substance of the moon exemplifies the dharma-kāya. The Great Sūtra says: 'The nature of the moon is ever round, truly having neither increase nor decrease.' Due to Mount Sumeru, there are waning and waxing. Without increasing, it increases, as the bright moon gradually becomes conspicuous; without decreasing, it decreases, as the dark moon gradually disappears. The dharma-kāya is also like this: in reality it has neither wisdom nor severance; due to ignorance, when discussing wisdom in reference to suchness, suchness is truly not wisdom; when discussing severance in reference to suchness, suchness is truly not severed. Though without wisdom, there is wisdom, and prajñā gradually shines; though without severance, there is severance, and liberation is gradually departed from. Taking the moon as an analogy, one knows these are the stages of wisdom and severance in the perfect teaching. The Great Sūtra says, 'From the beginning, I establish the sons in the secret treasury, the three virtues of nirvāṇa, and afterwards I shall enter parinirvāṇa in this secret treasury.' This is precisely the final wisdom and severance.
