Matsya Purana — Inquiry into Yayāti’s Story and the Kacha–Devayānī Episode
निधिं निधीनां वरदं वराणां ये नाद्रियन्ते गुरुमर्चनीयम् प्रालेयाद्रिप्रोज्ज्वलद्भालसंस्थं पापांल्लोकांस्ते व्रजन्त्यप्रतिष्ठाः //
nidhiṃ nidhīnāṃ varadaṃ varāṇāṃ ye nādriyante gurumarcanīyam prāleyādriprojjvaladbhālasaṃsthaṃ pāpāṃllokāṃste vrajantyapratiṣṭhāḥ //
Those who do not honor the Guru—worthy of worship, the treasure among treasures and bestower of the highest boons, radiant like the shining summit of the Himālaya—go, without standing or dignity, to sinful realms.
It does not teach Pralaya directly; it uses the Himālaya’s radiant summit as an image for the Guru’s exalted stature, while emphasizing karmic consequence—disrespect leads to descent into sinful realms.
For both king and householder, dharma begins with honoring the teacher who transmits right conduct and sacred knowledge; neglecting the Guru undermines righteous governance and personal discipline, producing loss of reputation and adverse afterlife results.
The verse is primarily ethical and ritual in tone: it calls the Guru 'arcanīya' (worthy of worship), implying the propriety of guru-arcana (reverential worship/rites), but it does not give Vāstu or temple-building rules in this line.
