菩薩瓔珞本業經 1.57

1.57

「佛子！四、量同佛力。所謂三相：諸法本無假名生，已有還無假名滅，不空有法假名住。是故一切通達空而不二名世諦相空，空一諦相故。

"Buddha-son! Fourth is having a measure equal to the Buddha's powers, that is to say, the three marks: all phenomena are fundamentally non-existent and arise by provisional designation; having existed, they revert to non-existence and cease by provisional designation; non-empty existing phenomena abide by provisional designation. Therefore, thoroughly realizing that everything is empty and non-dual is called the emptiness of the marks of worldly truth, because the mark of the one truth is empty.
