2.10.39

anena vijñāpitam evam āha tad dīyatāṃ ced yadi tattvam asti /[ś]
rājñaḥ samīpe varakāram āha prajñāpanaiṣā vividhopadiṣṭā //[ś]

Thus says (the messenger); so says (the king); if there is any truth in this (statement of the messenger), then the thing (agreed to) should at once be surrendered; (the messenger) has informed the king of all the deeds of the enemy. (Parakára);—this is the writ of information which is held to be of various forms.
