Thirukkural 540 in English

Worse than wrath in excess is Forgetfulness in joy-excess

Negligence kills renown just as Ceaseless want wisdom destroys

Forgetful nature fails of fame All schools of thinkers say the same

The fearful find no fortress here The forgetful find good never

Failing foresight the guardless man Shall rue his folly later on

Forget none; watch with wakeful care Miss none; the gain is sans compare

With cautious care pursue a thing Impossible there is nothing

Do what the wise commend as worth If not, for seven births no mirth

When joy deludes, their fate recall Whom negligence has made to fall
