首楞嚴義疏注經 2.37

2.37

佛告大王：「汝見變化遷改不停，悟知汝滅；亦於滅時，汝知身中有不滅耶？」波斯匿王合掌白佛：「我實不知。」

The Buddha told the great king, 'You see changes and alterations occurring without rest, and realize and know that you will perish; yet at the time of perishing, do you know whether there is that within your body which does not perish?' King Prasenajit pressed his palms together and addressed the Buddha, 'I truly do not know.'
