[120] And what, bhikkhus, is aging-and-death (jarāmaraṇa)? The aging of the various beings in the various orders of beings — their growing old, brokenness of teeth, greyness of hair, wrinkling of skin, the decline of the life span, the maturing of the faculties (indriya): this is called aging. The passing away of the various beings from the various orders of beings — their falling away, breaking up, disappearance, mortality, death (maraṇa), the completion of time, the breaking up of the aggregates, the laying down of the carcass, the cutting off of the life faculty: this is called death. Thus this aging and this death — this, bhikkhus, is called aging-and-death. With the origin of birth (jāti) there is the origin of aging-and-death; with the cessation of birth there is the cessation of aging-and-death. This very Noble Eightfold Path is the way of practice leading to the cessation of aging-and-death, namely: right view … right concentration (samādhi).
