satyena sūryastapati satyenāgniḥ pradīpyate |
satyena māruto vāti sarvaṃ satye pratiṣṭhitam || 30 ||

There are heroes in respect of obedience to mothers, and heroes in the matter of the life of mendicancy they lead. There are heroes in the matter of hospitality to guests, whether living as householders. All these heroes attain to very superior, regions of felicity which are, of course, acquired by them as the rewards of their own acts. Holding all the Vedas in memory, or ablutions performed in all the sacred waters, may or may not be equal to telling the Truth every day in one's life. A thousand horse sacrifices and Truth were once weighed in the balance. It was seen that Truth weighed heavier than a thousand horse-sacrifices. It is by Truth that the sun is imparting heat, it is by Truth that fire blazes up, it is by Truth that the winds blow; verily, everything rests upon Truth. It is Truth that gratifies the deities, the Pitris and the Brahmanas. Truth has been said to be the highest duty. Therefore, no one should ever transgress Truth. The Munis are all devoted to Truth. Their prowess depends upon Truth. They also swear by Truth. Hence, Truth is pre-eminent. All truthful men, O chief of Bharata's race, succeed by their truthfulness in attaining to heaven and sporting there in felicity. Self-restraint is the attainment of the reward that attaches to Truth. I have discoursed on it with my whole heart. The man of humble heart who is possessed of self-restraint, without doubt, attains to great honours in heaven.
