Nitishatak Shaloka-6

      The endeavours of a man to bring a blockhead to the right path by the influence of his wise and mellifluous words are nowise better than the fruitless efforts of  one who ventures to keep an elephant fast bound by means of the delicate threads of a lotus stem, or to pierce a diamond by the tender fibres of  shirisa, or to sweeten the saline waters of vast ocean by pouring a single drop of nectar into its midst.-Bhartrihari (Translated by Purohit Gopi Nath, M.A., 1914)
