Puṣkara-Śapatha Itihāsa (Agastya–Indra Dispute at the Tīrthas) | पुष्कर-शपथ-आख्यानम्
त्यागस्य चापि सम्पत्ति: शिष्यते तप उत्तमम् | सदोपवासी च भवेद् ब्रह्मचारी तथैव च
tyāgasya cāpi sampattiḥ śiṣyate tapa uttamam | sadopavāsī ca bhaved brahmacārī tathaiva ca ||
Bhīṣma dit : «La véritable “richesse” du renoncement est enseignée comme l’austérité suprême. Il faut vivre dans une abstinence constante —c’est-à-dire la maîtrise de la nourriture— et, de même, demeurer brahmacārin, discipliné dans la continence et la conduite.»
भीष्म उवाच
Bhīṣma frames renunciation as a real spiritual ‘wealth’ and identifies the highest tapas as disciplined self-restraint—especially control of appetite (upavāsa) and celibate, regulated conduct (brahmacarya).
In Anuśāsana Parva, Bhīṣma continues instructing Yudhiṣṭhira on dharma. Here he emphasizes ascetic disciplines as practical expressions of renunciation, presenting fasting and brahmacarya as exemplary vows.
