Thirukkural

Kural - 931
Seek not the gamester's play; though you should win,
Your gain is as the baited hook the fish takes in.
Though able to win, let not one desire gambling; (for) even what is won is like a fish swallowing the iron in fish-hook.

Kural - 932
Is there for gamblers, too, that gaining one a hundred lose, some way
That they may good obtain, and see a prosperous day?
Is there indeed a means of livelihood that can bestow happiness on gamblers who gain one and lose a hundred ?

Kural - 933
If prince unceasing speak of nought but play,
Treasure and revenue will pass from him away.
If the king is incessantly addicted to the rolling dice in the hope of gain, his wealth and the resources thereof will take their departure and fall into other's hands.

Kural - 934
Gaming brings many woes, and ruins fair renown;
Nothing to want brings men so surely down.
There is nothing else that brings (us) poverty like gambling which causes many a misery and destroys (one's) reputation.

Kural - 935
The dice, and gaming-hall, and gamester's art, they eager sought,
Thirsting for gain- the men in other days who came to nought.
Penniless are those who by reason of their attachment would never forsake gambling, the gambling-place and the handling (of dice).

Kural - 936
Gambling's Misfortune's other name: o'er whom she casts her veil,
They suffer grievous want, and sorrows sore bewail.
Those who are swallowed by the goddess called "gambling" will never have their hunger satisfied, but suffer the pangs of hell in the next world.

Kural - 937
Ancestral wealth and noble fame to ruin haste,
If men in gambler's halls their precious moments waste.
To waste time at the place of gambling will destroy inherited wealth and goodness of character.

Kural - 938
Gambling wastes wealth, to falsehood bends the soul: it drives away
All grace, and leaves the man to utter misery a prey.
Gambling destroys property, teaches falsehood, puts an end to benevolence, and brings in misery (here and hereafter).

Kural - 939
Clothes, wealth, food, praise, and learning, all depart
From him on gambler's gain who sets his heart.
The habit of gambling prevents the attainment of these five: clothing, wealth, food, fame and learning.

Kural - 940
Howe'er he lose, the gambler's heart is ever in the play;
E'en so the soul, despite its griefs, would live on earth alway.
As the gambler loves (his vice) the more he loses by it, so does the soul love (the body) the more it suffers through it.
