Adhyaya 40: Kali-yuga Lakshana, Yuga-sandhyamsha, and the Re-emergence of Dharma
अनागतेषु तद्वच्च तर्कः कार्यो विजानता मन्वन्तरेषु सर्वेषु अतीतानागतेष्विह
anāgateṣu tadvacca tarkaḥ kāryo vijānatā manvantareṣu sarveṣu atītānāgateṣviha
In the manvantaras yet to come as well, the discerning knower should employ the same reasoning; for in all manvantaras—past and future—the principle is to be understood through reflective inquiry.
Suta Goswami (narrating the Purana to the sages of Naimisharanya)
It teaches that the principles guiding Linga devotion and Shiva-tattva are not confined to one age; the same discerning inquiry applies across all cosmic cycles, strengthening steady (niṣṭhā) worship of Pati beyond changing outer forms.
By asserting continuity across past and future manvantaras, it implies Shiva’s status as the unchanging Pati—ever the same reality—while worlds and orders change; thus Shiva-tattva is timeless and knowable through right discernment.
It highlights jñāna-yukta sādhanā—using tarka (reflective discrimination) as an aid to Pashupata-oriented understanding, so practice is guided by insight rather than mere custom.
