Dhammapada 2.4.26

2.4.26

‘‘Pamādamanuyuñjanti, bālā dummedhino janā;
Appamādañca medhāvī, dhanaṃ seṭṭhaṃva rakkhati.

26. Simpletons, folk of little intelligence, are given to heedlessness;
But the intelligent man preserves heedfulness as his greatest treasure.
27. Give not yourselves up to heedlessness; indulge not in lust and sensual pleasure;
For he that is heedful and practices meditation attains profound happiness.
