Tīrtha-vaṃśa Upadeśa: Instruction on the Fruits of Sacred Waters
सावित्रीं जपते यस्तु त्रिकालं भरतर्षभ । भिक्षावृत्ति: कियावांश्व स राजन् केतनक्षम:
sāvitrīṃ japate yas tu trikālaṃ bharatarṣabha | bhikṣāvṛttiḥ kiyāvāṃś ca sa rājan ketanakṣamaḥ ||
भरतर्षभ! यस्तु सावित्रीं त्रिकालं जपति, भिक्षावृत्तिः क्रियावांश्च, स राजन् केतनक्षमः।
भीष्म उवाच
Eligibility for receiving honor in ancestral rites (śrāddha) is grounded in disciplined daily spiritual practice (trikāla-japa of Sāvitrī), austere livelihood (bhikṣā-vṛtti), and steadfast performance of prescribed duties (kriyā). The verse links ritual worthiness to sustained ethical-religious conduct rather than status alone.
In the Anuśāsana Parva, Bhīṣma instructs King Yudhiṣṭhira on dharma and proper ritual standards. Here he specifies the kind of person who should be invited to a śrāddha: a disciplined practitioner of the Sāvitrī/Gāyatrī, living simply on alms and devoted to correct observances.
