Temiyajātaka

Suttapiṭaka · Khuddakanikāya · Jātaka (2) · Vol. 28 · Section 439

[439] The world is stricken by death (maccu) and hemmed in by aging (jarā); the nights pass not in vain — know this, O khattiya. Just as, when the warp is stretched upon the loom, whatever length has been woven, but little remains to be woven: even so is the life of mortals. Just as a river in full flood, flowing on, does not turn back, even so the life span of human beings, moving on, does not turn back. Just as a river in full flood sweeps away the trees grown along its banks, even so are all living beings swept away by aging and by death (maraṇa).
