法華玄義釋籤 12.49

12.49

三世之上更加三世，故得更論，乃成九世論交互也。故《華嚴》中十種三世，九世為九更加三世說平等，以為十種。《大纓珞》中亦明九世，是故今文重約三世。

Adding the three times on top of the three times allows one to treat them further, thereby forming the nine times to discuss their mutual interactions. Thus, in the Huayan [Sūtra], there are ten kinds of three times: the nine times make nine, and adding the three times that are stated to be equal makes ten kinds. The Da yingluo [jing] also clarifies the nine times; therefore, the present text re-examines them in terms of the three times.
