असंखयं जीवियं मा पमायए, जरोवणीयस्स हु णत्थि ताणं ।
एवं वियाणाहि जणे पमत्ते, किण्णू विहिंसा अजया गहिति ॥४.१॥
Life is immeasurably short — do not be negligent. For one being carried toward old age, there is truly no protection. Knowing this about the negligent person, why would sin not seize the one who is unrestrained?
This opening verse establishes the chapter's core thesis: life is fleeting and old age provides no shelter. The word "immeasurably short" is not poetic exaggeration — it is a precise observation that the moments available for spiritual practice are finite and dwindling. The rhetorical question at the end is pointed: if you are negligent and unrestrained, harmful actions will naturally accumulate, and their consequences cannot be escaped. This is not a threat — it is cause and effect.
The simple version: Life is incredibly short. Old age comes for everyone, and when it does, nothing protects you. A careless, unrestrained person naturally falls into sinful actions — and those consequences will come back, without exception. Don't be that person.
