Amāvasyā-Pitṛtarpaṇa: Purūravas and the Soma-Based Ancestral Offering (अमावस्या-पितृतर्पण / सोमतर्पण-विधि)
इत्येत पितरो देवा मनुष्यपितरश्च ये / प्रीतेषु तेषु प्रीयन्ते श्राद्धयुक्तेषु कर्मसु
ityeta pitaro devā manuṣyapitaraśca ye / prīteṣu teṣu prīyante śrāddhayukteṣu karmasu
Thus the Pitṛs who are gods, and the Pitṛs of humankind: when they are pleased, they delight in rites performed in union with Śrāddha.
