24. lo bye ba phrag dgu brgya nyi shu rtsa gcig dang / lo brgya phrag stong drug cu [=bcu]. The numbers in this passage are even more curious than they are in the previous passages, given that here the initial number of years in human time, stong phrag drug cu [=bcu], i.e., sixty thousand, departs from the pattern in which the initial numbers increase twofold at each juncture. Following the pattern, eight hundred years would become sixteen hundred years. Multiplying sixteen hundred (years) times thirty (days) times twelve (months) times sixteen thousand (years) yields nine billion two hundred sixteen million years.
