7.174

法中始生等者。託蘊腹中名生，形體未成即有死者。纔生者，生下即死也。暫停住者，五歲十歲乃至百歲通名暫住。初天所見，人間半百尚同晝夜，況聖智乎。故《正法念經》云：「有於胎藏中死，有生而已命終，有能行便亡，有能走便卒，雖修短之異皆歸死處。」故《淨名》云：「是身虛偽，假以澡浴衣食，必歸磨滅。」

"In the dharma [signified], from its first arising, etc.": taking hold of the aggregates in the womb is called "birth"; those whose form and body are not yet completed may already die. "Just born" means dying immediately upon birth. "Temporarily abiding": five years, ten years, or up to a hundred years are all generally called "temporarily abiding." As seen by the first heaven, fifty years in the human world is merely like a single day and night; how much more so to the noble wisdom! Thus the Saddharmasmṛtyupasthāna-sūtra says: "Some die in the womb; some have their lives end as soon as they are born; some perish as soon as they can walk; some die suddenly as soon as they can run. Although they differ in longevity, all return to the place of death." Hence the Vimalakīrtinirdeśa says: "This body is false and deceptive; though provisionally sustained with bathing, clothing, and food, it must inevitably return to destruction."
