Now, among the nine grades severed, the first grade impairs two rebirths, leaving five rebirths remaining. If one severs the afflictions of the second and third grades, they further impair two rebirths, leaving three rebirths remaining. If one severs the fourth grade, it further impairs one rebirth, leaving two rebirths remaining. Therefore, if one severs three or four grades, with two or three rebirths remaining, this is called *kolaṃkola*. If one severs the fifth, within a single rebirth one will definitely sever the sixth.
