Jñāna-yoga and Karma-phala: Manu–Bṛhaspati on Akṣara and the Limits of Mantra
तीर्थानां हृदयं तीर्थ शुचीनां हृदयं शुचि: । सर्वमार्यकृतं चौक्ष्यं वालसंस्पर्शनानि च
tīrthānāṁ hṛdayaṁ tīrthaṁ śucīnāṁ hṛdayaṁ śuciḥ | sarvam āryakṛtaṁ caukṣyaṁ vāla-saṁsparśanāni ca ||
Bhīṣma said: “Among sacred fords and pilgrim-places, the truest tīrtha is a purified heart; and among things deemed pure, the purest is likewise a purified heart. Whatever is practiced by the noble and well-bred is to be regarded as supremely clean; even contacts such as the touch of hairs (like those used in a yak-tail whisk) are considered pure when sanctioned by refined conduct.”

Educational Q&A
True purity is primarily internal: a purified heart is the highest tīrtha and the purest purity. Social and ritual notions of cleanliness are validated when grounded in the refined conduct (ācāra) of noble persons, emphasizing ethical intention over mere external form.
In Śānti Parva, Bhīṣma instructs Yudhiṣṭhira on dharma after the war. Here he explains standards of purity: inner purity is supreme, and customary practices accepted among the cultured (such as contact with whisk-hairs used in royal service) are considered pure because they are endorsed by proper conduct.
