“ The fraudful forfeit life and being here below;
Who fraud eschew the bliss of heavenly beings know.
Even their body will fail the fraudulent; but even the world of the gods will not fail those who are free from fraud. ”

“ Who neighbour's goods desire, and watch for his unguarded hour.
The study of kindness and the exercise of benevolence is not with those who watch for another's forgetfulness, though desire of his property. ”

“ In whom inveterate lust of fraudful gain is found.
They cannot walk steadfastly, according to rule, who eagerly desire to defraud others.
Kural - 287
Practice of fraud's dark cunning arts they shun,
Who long for power by 'measured wisdom' won.
That black-knowledge which is called fraud, is not in those who desire that greatness which is called rectitude. ”
