Amāvasyā-Pitṛtarpaṇa: Purūravas and the Soma-Based Ancestral Offering (अमावस्या-पितृतर्पण / सोमतर्पण-विधि)
तेषां गतिं सतत्त्वां च प्राप्तिं श्राद्धस्य चैव हि / न मृतानां गतिः शक्या ज्ञातुं न पुनरागतिः
teṣāṃ gatiṃ satattvāṃ ca prāptiṃ śrāddhasya caiva hi / na mṛtānāṃ gatiḥ śakyā jñātuṃ na punarāgatiḥ
Their course, their true nature, and the attainment of the fruit of śrāddha are not truly knowable with certainty; the path of the departed cannot be known, nor is there any return again.
