[320] And so, bhikkhus, being myself subject to birth (jāti), having understood the danger in what is subject to birth, seeking the unborn, unsurpassed security from bondage (yogakkhema) — Nibbāna — I attained the unborn, unsurpassed security from bondage, Nibbāna. Being myself subject to aging … being myself subject to sickness … being myself subject to death … being myself subject to sorrow … being myself subject to defilement (saṅkilesa), having understood the danger in what is subject to defilement, seeking the undefiled, unsurpassed security from bondage, Nibbāna, I attained the undefiled, unsurpassed security from bondage, Nibbāna. And the knowledge (ñāṇa) and vision arose in me: 'My liberation is unshakable; this is my last birth; now there is no renewed existence.'
