Thirukkural-On Virtue-Avoidance of Fraud-Kural-287

Add as a preferred source on Google

Those who abide by the guidelines of wisdom,
Progressing towards righteousness,
Will never be guilty of dark and fraudulent crime.

Those who practise the code of righteousness will not go in for expertise in crime and fraud. The poet has juxtaposed the expertise in crime against the counsel of righteousness, in this Kural. K V Jegannathan in his detailed research-oriented edition of the Tirukkural has quoted an expression which occurs in Soolamani, which could mean criminal expertise.
