मानसतीर्थ-शौचप्रशंसा | Praise of the ‘Mental Tīrtha’ and the Marks of Purity
परस्त्रियं नाभिलषेद् वाचाथ मनसापि वा । अनृतं च न भाषेत मातापित्रो: कृतेपि वा
parastriyaṁ nābhilaṣed vā cātha manasāpi vā | anṛtaṁ ca na bhāṣeta mātāpitroḥ kṛte 'pi vā ||
毗湿摩说道：不可贪恋他人之妻——无论以言语，乃至于心念。亦不可妄语，即便是为了父母也不可。此教诲昭示：内在的自制与真实，是法（dharma）的根本修持；道德之责，不止于外在行为，更及于意向本身。

Educational Q&A
Two restraints are emphasized: (1) do not covet another’s wife, not even mentally or through suggestive speech; (2) do not speak falsehood, even when motivated by filial loyalty. Dharma requires purity of intention and unwavering commitment to truth.
In Anuśāsana Parva, Bhīṣma instructs Yudhiṣṭhira on dharma. This verse is part of Bhīṣma’s ethical counsel, laying down personal conduct rules that govern desire and speech.
