"The Rakshasa said, 'Since thou art observant of the duties under all circumstances, therefore, O king of the Kaikeyas, go back to thy abode. Blessed be thou, I leave thee. They, O king of the Kaikeyas, who protect kine and [paragraph continues] Brahmanas and all their subjects, have nothing to fear from Rakshasas, and much less from sinful persons. Those kings that give the lead to Brahmanas and whose might depends upon that of the Brahmanas, and whose subjects discharge the duties of hospitality, always succeeds in acquiring heaven.'
