Amāvasyā-Pitṛtarpaṇa: Purūravas and the Soma-Based Ancestral Offering (अमावस्या-पितृतर्पण / सोमतर्पण-विधि)
गृहस्था ये च यज्वान ऋतुर्बर्हिषदो ध्रुवम् / गृहस्थाश्चाप्ययज्वान अग्निष्वात्तास्तथार्त्तवाः
gṛhasthā ye ca yajvāna ṛturbarhiṣado dhruvam / gṛhasthāścāpyayajvāna agniṣvāttāstathārttavāḥ
Householders who perform yajña are indeed called Ṛtu and Barhiṣad. Householders who do not perform yajña are called Agniṣvātta and Ārttava.
