Tiruvalluvar

“ What's the worth of shaven head or tresses long,
If you shun what all the world condemns as wrong?
There is no need of a shaven crown, nor of tangled hair, if a man abstain from those deeds which the wise have condemned. ”

“ Is show of virtuous might when weakness lurks within.
The assumed appearance of power, by a man who has no power (to restrain his senses and perform austerity) , is like a cow feeding on grass covered with a tiger's skin. ”

“ Foul in heart, yet high upraised of men in virtuous fame.
There are many men of masked conduct, who perform their ablutions, and (make a show) of greatness, while their mind is defiled (with guilt) . ”
