Mbh 12.199.31b

Truth is the origin of creatures. Truth is their progeny. It is by Truth that the Wind moves. It is by Truth that the Sun gives heat. It is by Truth that Fire burns. It is on Truth that Heaven rests. Truth is Sacrifice, Penance, Vedas, the utterance of Samans, Mantras, and Saraswati. It hath been heard by us that once on a time Truth and all religious observances were placed on a pair of scales. When both were weighed, that scale on which Truth was seen to be heavier. There is Truth where Righteousness is. Everything increaseth through Truth. Why, O king, dost thou wish to do an act that is stained with falsehood? Be firm in Truth. Do not act falsely, O monarch! Why wouldst thou falsify thy words "Give (me)," which thou hast uttered? If thou refusest, O monarch, to accept the fruits that I have given thee of my recitations, thou shalt then have to wander over the world, fallen away from Righteousness! That person who does not give after having promised, and he also that does not accept after having solicited, are both stained with falsehood. It behoveth thee, therefore, not to falsify thy own words.'
