दुमपत्ते पंडुयए जहा, णिवडइ राइगणाण अच्चए। एवं मणुयाण जीवियं, समयं गोयम मा पमायए ॥१०.१॥
As a pale, yellowed leaf falls from the tree when the days and nights have passed — so is human life. O Gautam, do not be negligent for even a moment.
The image is exact: a leaf turns yellow slowly, unseen, and then one day it simply falls. Human life is the same. We do not feel it ending — but day by day, the vitality drains away. The scripture opens with this image to jolt the practitioner awake. The address "O Gautam" is intimate and urgent; it speaks to the chief disciple but is meant for every seeker who reads it.
The simple version: Your life is like a dying leaf on a tree. It looks fine until suddenly it falls. Don't assume you have time — use this moment.
