Amāvasyā-Pitṛtarpaṇa: Purūravas and the Soma-Based Ancestral Offering (अमावस्या-पितृतर्पण / सोमतर्पण-विधि)
इत्यर्कपितृसोमानामैलस्य च समागमः / सुधामृतस्य च प्राप्तिः पितॄणां चैव तर्प्पणम्
ityarkapitṛsomānāmailasya ca samāgamaḥ / sudhāmṛtasya ca prāptiḥ pitṝṇāṃ caiva tarppaṇam
Thus is told the meeting of Arka, the Pitṛs, and Soma, and also the coming together of Aila (Purūravas); the gaining of the nectar Sudhā-amṛta, and the tarpaṇa—oblations of satisfaction—offered to the Pitṛs.
