大般涅槃經義記 3.123

3.123

第五句中，化善師彼名「分半國與是童子」，亦可統眾與之共匡名分半國與童子也，同化日久名「共治國，經歷多年」。

In the fifth clause, the good transformation taking him as master is called 'dividing half the state and giving it to this young man'; or it can also mean that taking charge of the assembly to guide together with him is called dividing half the state and giving it to the young man. Being united in transformation for a long time is called 'governing the state together, passing through many years.'
