Amāvasyā-Pitṛtarpaṇa: Purūravas and the Soma-Based Ancestral Offering (अमावस्या-पितृतर्पण / सोमतर्पण-विधि)
मनुष्यपितरश्चैव तेभ्यो ऽन्ये लौकिकाः स्मृताः / पिता पितामहश्चापि तथा यः प्रपितामहः
manuṣyapitaraścaiva tebhyo 'nye laukikāḥ smṛtāḥ / pitā pitāmahaścāpi tathā yaḥ prapitāmahaḥ
There are also human Pitṛs; and distinct from them are others remembered as ‘laukika’, the worldly Fathers—one’s father, grandfather, and great-grandfather.
