Anuśāsana-parva Adhyāya 112: Dharma as the sole companion; karmic witnesses; rebirth sequences
Bṛhaspati–Yudhiṣṭhira Saṃvāda
अगाधे विमले शुद्धे सत्यतोये धृतिहदे । स्नातव्यं मानसे तीर्थे सत्त्वमालम्ब्य शाश्वतम्
bhīṣma uvāca | agādhe vimale śuddhe satyatoye dhṛtihade | snātavyaṃ mānase tīrthe sattvam ālambya śāśvatam ||
ビーシュマは言った。「深く測りがたく、垢なく澄み、完全に清浄なる心のティールタがある。そこでは、堅忍（ドゥリティ）が池となり、真実（サティヤ）が水となる。人は常にそこに“沐浴”し、永遠の至上我に帰依すべきである。」

Educational Q&A
True purification is primarily inward: one should 'bathe' in a mental tīrtha made of truth (satya) and steadfastness (dhṛti), continually relying on the Eternal Self. Ethical integrity and inner firmness are presented as the real sacred waters.
In Anuśāsana Parva, Bhishma instructs Yudhiṣṭhira on dharma. Here he uses a metaphor of pilgrimage: instead of emphasizing external bathing alone, he praises an inner sacred place—purity of mind grounded in truth and fortitude.
