Tapas-śreṣṭhatā: Anāśana as the Highest Austerity
Bhagīratha–Brahmā Saṃvāda
भीष्म उवाच तप: प्रचक्षते यावत् तावल्लोको युधिष्छिर । मतं ममात्र कौन्तेय तपो नानशनात् परम्
Bhīṣma uvāca: tapaḥ pracakṣate yāvat tāvāl loko Yudhiṣṭhira; mataṃ mamātra Kaunteya, tapo nānāśanāt param.
Bhishma said: “O Yudhishthira, a person is said to attain higher worlds in proportion to the austerity he performs. Yet, O son of Kunti, in my view there is no austerity greater than fasting.”
भीष्म उवाच
Bhishma teaches that spiritual merit and the attainment of higher realms correspond to one’s austerity, and he elevates fasting (anāśana) as the supreme form of tapas—highlighting restraint over bodily appetite as a powerful ethical-spiritual discipline.
In Anushasana Parva, Bhishma instructs Yudhishthira on dharma and disciplines that generate merit. Here he addresses Yudhishthira directly, stating a general principle about tapas and then giving his specific judgment that fasting surpasses other austerities.
