Anuśāsana-parva Adhyāya 112: Dharma as the sole companion; karmic witnesses; rebirth sequences
Bṛhaspati–Yudhiṣṭhira Saṃvāda
वृत्तशौचं मन:शौचं तीर्थशौचमत: परम् । ज्ञानोत्पन्नं च यच्छौचं तच्छौचं परमं स्मृतम्
vṛttaśaucaṃ manaḥśaucaṃ tīrthaśaucam ataḥ param | jñānotpannaṃ ca yacchaucaṃ tacchaucaṃ paramaṃ smṛtam ||
毗湿摩说：有行持之净，有心意之净，有由圣地（tīrtha）而得之净；然而更在其上者，是由真知而生的清净。此知识所生之清净，被记为最高。

Educational Q&A
Purity has multiple forms—ethical conduct, mental integrity, and ritual/pilgrimage-based cleansing—but the highest purification is inner clarity born of true knowledge, because it transforms the root of intention and understanding.
In the Anushasana Parva’s instruction on dharma, Bhishma continues his teachings by ranking kinds of purity, emphasizing that wisdom-based inner purification surpasses external or merely ritual forms.
