“A distinguished brāhman learned in the Veda, a yogi, one who knows the Veda, one who has mastered the Jyeṣṭha-sāman, one who has thrice kindled the fire Nāciketa, one who knows the three verses which begun with ‘madhu,’[5] one who knows the ‘tri-suparṇa’ hymns, one who knows the six Vedāṅgas, a daughter’s son, a Ṛtvij priest, a daughter’s husband, and a sister’s son, and a father-in law also, and one who is skilled in the business of the five sacred fires, and one who is eminent in austerities, a maternal uncle, and one who is anterior to one’s parents, a disciple, a relative by marriage, and a kinsman—these brāhmans are all worthy of invitation to a śrāddha.
