Matsya Purana — The Battle at Tripura: Shiva’s Strategy
ते पीड्यमाना गुरुभिर् गिरिभिश्च गणेश्वराः कर्तव्यं न विदुः किंचिद् वन्द्यमाधार्मिका इव //
te pīḍyamānā gurubhir giribhiśca gaṇeśvarāḥ kartavyaṃ na viduḥ kiṃcid vandyamādhārmikā iva //
Crushed by heavy burdens and by mountains, those chiefs of the gaṇa-hosts could discern no duty to be done—like impious men who have forgotten what is worthy of reverence.
This verse is ethical rather than cosmogonic: it uses the image of being crushed by heavy forces to show how beings lose discernment of dharma; it does not directly describe pralaya, but it echoes the puranic theme that overwhelming calamity can accompany adharma.
It warns that when one is overwhelmed—by power, pressure, fear, or burdens—one may forget kartavya (duty) and vandyam (what deserves respect). For a king, this means policies made under coercion or arrogance drift into adharma; for a householder, it cautions against neglecting daily obligations and reverence to elders, teachers, and sacred norms.
No direct Vastu or temple-construction rule appears in this verse; the ritual takeaway is the emphasis on vandyam—maintaining reverence (toward deities, elders, and dharma) as a foundation for correct practice.
