Jarāmaraṇa

' is Sanskrit and Pāli for "old age" (') and "death" (). In Buddhism, jaramarana is associated with the inevitable decay and death-related suffering of all beings prior to their rebirth within saṃsāra (cyclic existence).

Jarā and maraṇa are identified as the twelfth link within the Twelve Links of Dependent Origination.

Etymology
The word jarā is related to the older Vedic Sanskrit word jarā, jaras, jarati, gerā, which means "to become brittle, to decay, to be consumed". The Vedic root is related to the Latin granum, Goth. kaurn, Greek geras, geros (later geriatric) all of which in one context mean "hardening, old age".

The word maraṇa is based on the Vedic Sanskrit root mṛ, mriyate which means death. The Vedic root is related to later Sanskrit marta, as well as to German mord, Lith. mirti, Latin morior and mors, and Greek μόρος, all of which mean "to die, death".

Within the Four Noble Truths
Within the teachings on the Four Noble Truths, jarā and maraṇa are identified as aspects of dukkha (suffering, anxiety, unsatisfactoriness). For example, The Discourse That Sets Turning the Wheel of Truth states:


 * "Now this, bhikkhus, for the spiritually ennobled ones, is the true reality which is pain: birth is painful, aging is painful, illness is painful, death is painful; sorrow, lamentation, physical pain, unhappiness and distress are painful; union with what is disliked is painful; separation from what is liked is painful; not to get what one wants is painful; in brief, the five bundles of grasping-fuel are painful." – Dhammacakkappavattana Sutta, Samyutta Nikaya, Translated by Peter Harvey

Elsewhere in the canon the Buddha further elaborates on Jarāmaraṇa (aging and death):


 * "And what is aging? Whatever aging, decrepitude, brokenness, graying, wrinkling, decline of life-force, weakening of the faculties of the various beings in this or that group of beings, that is called aging.


 * "And what is death? Whatever deceasing, passing away, breaking up, disappearance, dying, death, completion of time, break up of the aggregates, casting off of the body, interruption in the life faculty of the various beings in this or that group of beings, that is called death."

Within the twelve links of dependent origination
Jarāmaraa is the last of the Twelve Nidānas, directly conditioned by birth (jāti), meaning that all who are born are destined to age and die.

Texts
In the Buddhist Pali Canon's "Subjects for Contemplation Discourse" (Upajjhatthana Sutta, AN 5.57), the Buddha enjoins followers to reflect often on the following:
 * I am subject to aging, have not gone beyond aging....
 * I am subject to illness, have not gone beyond illness....
 * I am subject to death, have not gone beyond death....

In the Pali Canon, aging and death affect all beings, including gods, humans, animals and those born in a hell realm. Only beings who achieve enlightenment (bodhi) in this lifetime escape rebirth in this cycle of birth-and-death (sasāra).

As what the Buddha instructed King Pasenadi of Kosala about aging and death in the Pabbatopama Sutta (SN 3.25):
 * Like massive boulders,
 * mountains pressing against the sky,
 * moving in from all sides,
 * crushing the four directions,
 * so aging and death
 * come rolling over living beings:
 * noble warriors, brahmins, merchants,
 * workers, outcastes, & scavengers.
 * They spare nothing.
 * They trample everything.


 * So a wise person seeing his own good,
 * steadfast, secures confidence
 * in the Buddha, Dhamma, & Sangha.


 * One who practices the Dhamma in thought, word, & deed,
 * receives praise here on earth and after death rejoices in heaven.

The Dhammapada has one chapter known as "Jaravagga", that consisted of eleven verses about old age, (from verse 146 to 156).
