首楞嚴義疏注經 8.589

8.589

「無世間心，同世行事。於行事交了然超越，命終之後遍能出超、化無化境。如是一類名他化自在天。」

"‘Having no worldly mind, yet sharing in worldly dealings; clearly transcending the mingling in such dealings.’ After their lives end, they are everywhere able to surpass and transcend realms both transformed and non-transformed. Such a class is called the Heaven of Free Enjoyment of Others' Transformations."
