Dogo paid a visit to his sick fellow monk, Ungan.
"Where can I see you again if you die and leave only your corpse?" Dogo asked. "I will meet you where nothing dies," Ungan replied. Dogo criticized his response saying,
"What you should have said is that there is no place where nothing is born and nothing dies and that we need not see each other at all."
