अग्नीषोमोत्पत्तिः
Agni–Soma Origin and the Brahmāgnīṣomīya Doctrine
देवयानचरो विष्णो: पितृयाणश्व॒ तामस: । द्वावेतौ प्रेत्य पन्थानौ दिव॑ चाधश्ष गच्छत:
devayānacaro viṣṇoḥ pitṛyāṇaś ca tāmasaḥ | dvāv etau pretya panthānau divaṃ cādhaś ca gacchataḥ ||
देवयानचरः पन्था विष्णोः सत्त्वसमन्वितः। पितृयाणश्च पन्थानस्तामसोऽयम् उदाहृतः। एतौ द्वौ प्रेत्य पन्थानौ—दिवं चाधश्च गच्छतः॥

Bhīṣma teaches that post-mortem destiny is described in terms of two broad trajectories: an upward, divine course (Devayāna) associated with purity and higher realization, and an ancestral course (Pitṛyāna) characterized here as tamasic, tending toward lower or less luminous outcomes. The verse frames ethical-spiritual quality as shaping one’s direction after death.
In Śānti Parva’s instruction-setting, Bhīṣma is advising Yudhiṣṭhira on dharma and the consequences of conduct. Here he summarizes a cosmological-ethical map of the afterlife, distinguishing two routes by which departed beings are said to proceed—upward to higher worlds (linked with Viṣṇu) or downward to lower states.
