四分律行事鈔資持記 2.104

2.104

四偷蘭遮。墮嘷叫地獄。人間四百年，為天一日；萬二千年為一月，十四萬四千年為一年，一百四十四萬年為十年，一千四百四十萬年為百年，十四千四百萬年為千年，二十八千八百萬年為二千歲，五十七千六百萬年為四千歲。（千萬為億，成五十七億；十萬為千，成六十千；鈔與經文，皆云五十億者，脫七字耳。）

Fourth, sthūlātyaya: one falls into the Raurava hell. Four hundred human years equal one celestial day; twelve thousand years equal one month, one hundred forty-four thousand years equal one year, one million four hundred forty thousand years equal ten years, fourteen million four hundred thousand years equal one hundred years, one hundred forty-four million years equal one thousand years, two hundred eighty-eight million years equal two thousand years, five hundred seventy-six million years equal four thousand years. (Ten million is one yi, making fifty-seven yi; one hundred thousand is one "thousand", making sixty "thousand"; both the Manual and the sūtra text say "fifty yi", which merely omits the character "seven".)
