三彌勒經疏 1.165

1.165

經曰「爾時人壽」以下，第三出家相。謂《太子五夢經》云「彌勒生年三十得道，未曾作婚」，必觀五欲過患，不樂在家。然《賢劫經》云「彌勒有子名德力」。此經云五千年行嫁，云何會？答：大聖應物，非凡小思境。是故生年雖三十，而示行婚以產德力，有何失？問：女人年五千歲後出適者，何故《成佛經》云「五百歲出適」？答；一云《阿含經》、《大成佛經》皆五百歲行嫁故，五千語誤。一云彌勒始出世時，五千歲方出適。若久遠以後，五百歲始出適。既有興衰，婚始亦有遲疾也。在家未幾者，年三十而得道故。

From the sūtra's words 'At that time human lifespan' onward, this is the third aspect, going forth into homelessness. Namely, the Sūtra on the Crown Prince's Five Dreams says: 'Maitreya attained the Way at the age of thirty, having never married'; he must have observed the faults of the five desires and took no pleasure in household life. However, the Bhadrakalpa Sūtra says: 'Maitreya had a son named Balasthāma.' This sūtra says that marrying takes place at five thousand years; how are these reconciled? Answer: The great holy one responds to beings, which is not an object of thought for ordinary persons or Śrāvakas. Therefore, although his age was thirty, he manifested the practice of marriage in order to give birth to Balasthāma; what fault is there? Question: If women marry after five thousand years of age, why does the Attainment of Buddhahood Sūtra say 'they marry at five hundred years'? Answer: One interpretation says that both the Āgama and the Great Attainment of Buddhahood Sūtra state that marriage takes place at five hundred years, so 'five thousand' is an error in wording. Another interpretation says: when Maitreya first appears in the world, they only marry at five thousand years; in later times, long afterward, they begin to marry at five hundred years. Since there is flourishing and decline, the beginning of marriage also has delays and haste. Regarding 'not long in the household': this is because he attained the Way at the age of thirty.
