大乘義章 6.23

6.23

次就地別以論因起。地謂欲界乃至非想。依如《毘曇》，同地之中，十使相望皆得相生。若望他地，上得生下，下不生上。上地命終，得起下結，故言生下。要斷下結，得上禪定，得禪定已方起上結，故不生上。十使之義，略云如是。

Next is discussing causal arising in terms of the distinction of stages. "Stages" refers to the desire realm up to [the stage of] neither perception nor non-perception. According to the Abhidharma, within the same stage, the ten underlying afflictions in relation to one another can all mutually generate one another. If in relation to other stages, a higher [stage] can generate a lower one, but a lower one does not generate a higher one. When dying in a higher stage, one can give rise to the fetters of a lower stage; hence it is said that it generates the lower. One must abandon the lower fetters to attain the higher dhyāna-samādhi; having attained the dhyāna-samādhi, one only then gives rise to the higher fetters; therefore it does not generate the higher. The meaning of the ten underlying afflictions is roughly stated as this.
