Brāhmaṇya-प्रश्नः — The Inquiry into Attaining Brāhmaṇya
Mataṅga–Gardabhī Itihāsa
सुधां वै लभते भोक्तुं यो नरो जायते पुनः । सप्तगड़, त्रिगड़ और इन्द्रमार्गमें पितरोंका तर्पण करनेवाला मनुष्य यदि पुनर्जन्म लेता है तो उसे अमृत भोजन मिलता है (अर्थात् वह देवता हो जाता है।)
sudhāṃ vai labhate bhoktuṃ yo naro jāyate punaḥ | saptagaḍe, trigaḍe ca indrāmārge ca pitarāṃ tarpaṇaṃ kurvan manuṣyaḥ yadi punarjanma labhate tarhi tasya amṛtabhojanaṃ bhavati (arthāt sa devatā bhavati) ||
阿阇陀利耶言：“此人——若复受生——得享食苏陀（sudhā，甘露）之福。凡于名为七垒（Saptagaḍa）、三垒（Trigaḍa）与因陀罗之道（Indra’s road）的路途上，为祖灵（Pitṛs）行塔尔帕那（tarpana）奠水者——若再投生——便得不死之食；亦即升至天神之位。”

Educational Q&A
Faithful tarpaṇa (libations) to the Pitṛs is presented as a powerful dharmic act whose merit can elevate one’s post-mortem destiny—so much so that even if rebirth occurs, it is in a divine condition symbolized by ‘amṛta’ or ‘sudhā’ as nourishment.
Ajadriya is describing the फल (result) of performing ancestral offerings along specified sacred/celestial routes (Saptagaḍa, Trigaḍa, and Indra’s path), stating that such a performer, if reborn, attains a god-like state marked by access to immortal food.
