俱舍論記 27.47

27.47

「由壽種姓至機宜別故」者，釋下兩句，顯佛差別。或有諸佛壽年一百，或有諸佛壽二萬等。種謂種類，此據總說。姓即種中差別姓也。應知種中各有多姓，喬答摩是剎帝利中之一姓，喬中所生名喬答摩也。舊云瞿曇，訛也。曾聞往昔剎帝利種被賊篡位，父死子逃。有仙人慈，收其子養，意念其種不絕後嗣。後漸長大，有瞻星者白彼怨王：「剎帝利種還有星玉。」怨王出賞募人令捉。仙行去後，遂被捉獲，將送怨王。怨王逐令鏘身令罪。仙還所止，不見小兒，觀知所在，來至其所。知不可活，遙勸小兒令起世情，冀留遺體。小兒苦惱，有志不從。仙化密雲為其掩障，細雨沾灑暫息苦飢，現一女人以動其想。小兒緣此泄精於地，仙以牛糞承裹而歸，致甘蔗園。因日光觸，糞團開割生一男子，形容殊妙。後長為王，因以相傳為牛糞種，或名地種、或名日種迦葉波，此云飲光，即婆羅門種中之一姓也。或有諸佛身長丈六，或有諸佛復過於此。或有諸佛般涅槃後法住千年，或有諸佛般涅槃後法住七日等。餘文可知。

On the passage "Due to lifespan, lineage ... due to differences in capacity and suitability": This explains the lower two lines, showing the distinctions among Buddhas. Some Buddhas have a lifespan of one hundred years, while some Buddhas have a lifespan of twenty thousand years, and so forth. "Kind" (zhǒng) refers to general category, spoken broadly. "Lineage" (xìng) means the specific lineage within the category. One should know that within each category there are many lineages: Gautama is one lineage among the kṣatriyas, and one born among the Gau is called Gautama (formerly rendered Qutan, an error). It has been heard that in the past, when the kṣatriya lineage was usurped by a rebel, the father died and the son fled. A compassionate seer took in the son and raised him, wishing that his lineage should not lack descendants. Later, as he grew up, an astrologer informed the hostile king: "There is still a star-jewel of the kṣatriya lineage." The hostile king offered a reward to recruit men to capture him. After the seer went out, the boy was captured and sent to the hostile king. The hostile king ordered him impaled and executed. When the seer returned to his dwelling and did not see the child, he perceived through insight where he was and went there. Knowing he could not survive, he urged the boy from afar to give rise to worldly desires, hoping to preserve his lineage. Tormented by pain, the boy was firm in resolve and would not comply. The seer conjured dense clouds to screen him, fine rain sprinkled to temporarily relieve his suffering and hunger, and manifested a woman to stir his thoughts. Because of this, the boy discharged semen upon the ground. The seer gathered it in cow dung and carried it back, placing it in a sugarcane field. Touched by sunlight, the dung-ball split open and gave birth to a male child of exquisite appearance. Later he grew up to become a king, and from this lineage it was transmitted as the Cow Dung clan, also named Earth clan, or Sun clan. Kāśyapa—translated here as "Drinker of Light"—is a lineage among the brahmins. Some Buddhas have a body sixteen feet tall, while some Buddhas exceed this. After some Buddhas enter parinirvāṇa, the Dharma remains for a thousand years, while after other Buddhas enter parinirvāṇa, the Dharma remains for seven days, and so forth. The rest of the text is clear.
