3.1.p10

“The Tathāgata’s body of wisdom was a knowledge without limit or impediment. The Tathāgata’s body had accomplished liberation, had reached the end of destinations, and no longer would decide: ‘I will fall into birth and death again.’ The Tathāgata’s body had reached knowing and seeing the city [of nirvāṇa]. He knew whether other people had the capacity to be liberated or not. ‘Here they die, and there they’re born. Round they turn, reborn until the end of birth and death.’ He fully knew who was liberated and who wasn’t.
