udahrsyan varijani
suryotthane kumud vina
rajña tu nirbhaya loka
yatha dasyun vina nrpa
Translation:
O King Pariksit, when the autumn sun rose, all the lotus flowers blossomed happily, except the night-blooming kumut, just as in the presence of a strong ruler everyone becomes fearless, except the thieves.
