शकुनि (हिरण्मय-पक्षी) उपदेशः — Vighasāśin and the Difficulty of Gārhasthya
एतद्वो<स्तु तपोयुक्त ददामीत्यूषिचोदितम् । तस्मात् तत् तद् व्यवस्थानं तपस्वितप उच्यते
etad vo 'stu tapoyuktaṁ dadāmīty ūṣicoditam | tasmāt tat tad vyavasthānaṁ tapasvitapa ucyate |
„Dies sei für euch, mit Tapas verbunden; ich gewähre es“ — so verkündete es der inspirierte Seher. Darum heißt die unbeirrbare Hingabe an jede der vorgeschriebenen vedischen Pflichten das „Tapas“ eines Asketen: diszipliniertes Wirken im Opferhandeln, voll innerer Askese, durch das die ersehnten Früchte verliehen werden.

Tapas is not only physical austerity; for a practitioner it can mean unwavering, disciplined adherence to one’s prescribed Vedic duties—especially sacrificial action—performed with inner restraint and seriousness, which becomes the basis for receiving the intended fruits.
A seer’s pronouncement is cited: the rite should be performed ‘with tapas,’ and the fruits will be granted. From this, the text concludes that fully committing oneself to the proper performance of those specific rites is itself the ascetic’s tapas.
