Anuśāsana-parva Adhyāya 112: Dharma as the sole companion; karmic witnesses; rebirth sequences
Bṛhaspati–Yudhiṣṭhira Saṃvāda
शरीरस्य यथोद्देशा: शुचय: परिकीर्तिता: । तथा पृथिव्या भागाश्च पुण्यानि सलिलानि च
śarīrasya yathoddeśāḥ śucayaḥ parikīrtitāḥ | tathā pṛthivyā bhāgāś ca puṇyāni salilāni ca ||
Bhīṣma dijo: «Así como ciertas regiones del cuerpo humano son proclamadas por la tradición como puras y santificadoras, del mismo modo diversas regiones de la tierra son sagradas como tīrthas; y las aguas que allí se hallan otorgan mérito.»
भीष्म उवाच
Bhīṣma teaches an analogy: purity is not only a bodily concept (certain bodily spots being deemed sanctifying) but also a geographical one—specific places on earth function as tīrthas, and their waters are held to generate puṇya and aid purification.
In the Anuśāsana Parva’s instruction on dharma, Bhīṣma continues his discourse by explaining the sanctity of pilgrimage sites and sacred waters, framing them through a familiar comparison with the traditionally ‘pure’ regions of the human body.
