Amāvasyā-Pitṛtarpaṇa: Purūravas and the Soma-Based Ancestral Offering (अमावस्या-पितृतर्पण / सोमतर्पण-विधि)
आप्याययत्सुषुम्णातः पुनस्तान्सोमपायिनः / निः शेषायां कलायां तु सोममाप्याययत्पुनः
āpyāyayatsuṣumṇātaḥ punastānsomapāyinaḥ / niḥ śeṣāyāṃ kalāyāṃ tu somamāpyāyayatpunaḥ
From Suṣumṇā he again nourishes those who drink Soma; and when the kalā is exhausted without remainder, he replenishes Soma once more.
