" 'Just as, when rain falls from the sky in thick drops, a bubble appearing on the water will quickly vanish and will not last long; even so, brahmins, is human life like a water bubble. It is short, limited, and brief; it is full of suffering, full of tribulation. This one should wisely understand. One should do good and live a pure life; for none who is born can escape death.' "

-- Anguttara Nikaya 7:70
