Bṛhaspati–Yudhiṣṭhira Saṃvāda
एवं शरीरशौचेन तीर्थशौचेन चान्वित: । शुचि: सिद्धिमवाप्रोति द्विविधं शौचमुत्तमम्
evaṁ śarīra-śaucena tīrtha-śaucena cānvitaḥ | śuciḥ siddhim avāpnoti dvividhaṁ śaucam uttamam ||
毗湿摩说道：具足身之清净，又得圣地（tīrtha，渡口圣所）所成之清净者，方为真正清净，并能获得灵性圆满。此二重清净，被称为最上之净。

Educational Q&A
The verse teaches that the highest purity is twofold: maintaining bodily cleanliness and cultivating sanctifying purity associated with tīrthas (sacred places/rites). When both are present, one becomes truly pure and attains spiritual success.
In the Anuśāsana Parva, Bhīṣma is instructing Yudhiṣṭhira on dharma. Here he emphasizes the value of śauca (purity), presenting it as a practical ethical discipline that supports spiritual attainment.
