पञ्चतंत्र - काकोलूकीय - शत्रु

य उपेक्षेत शत्रुं स्वं प्रसरन्तं यदृच्छया ||
रोगं चालस्यसंयुक्तं स शनैस्तेन हन्यते ||

- पञ्चतंत्र, काकोलूकीय

A person who ignores an enemy who is growing from strength to strength, who ignores an ailment due to laziness - both share the same fate. They will both be, in time, killed by what they ignored.

- Panchatantra, Kakolukiya
