Anguttara Nikaya (Coleção dos Discursos Numerados) 1:33
SUJATO‘na kho ahaññeveko jarādhammo jaraṁ anatīto, atha kho yāvatā sattānaṁ āgati gati cuti upapatti sabbe sattā jarādhammā jaraṁ anatītā’ti.
‘It’s not just me who is liable to grow old, not being exempt from old age. For all sentient beings grow old according to their nature, as long as they come and go, pass away and are reborn.’
