Amāvasyā-Pitṛtarpaṇa: Purūravas and the Soma-Based Ancestral Offering (अमावस्या-पितृतर्पण / सोमतर्पण-विधि)
पूर्णा मावास्ययोः कालो यातनास्थानमेव च / समासात्कीर्तितस्तुभ्यमेष सर्गः मनातनः
pūrṇā māvāsyayoḥ kālo yātanāsthānameva ca / samāsātkīrtitastubhyameṣa sargaḥ manātanaḥ
The time of the full-moon and the new-moon, and also the place of torment—these I have declared to you in brief. This sarga is ancient, without beginning.
