Matsya Purana — Marks of Karma-yoga and the Five Great Daily Sacrifices
कर्मयोगं विना ज्ञानं कस्यचिन् नेह दृश्यते श्रुतिस्मृत्युदितं धर्मम् उपतिष्ठेत्प्रयत्नतः //
karmayogaṃ vinā jñānaṃ kasyacin neha dṛśyate śrutismṛtyuditaṃ dharmam upatiṣṭhetprayatnataḥ //
Without the discipline of karma-yoga, true knowledge is not seen to arise in anyone here. Therefore one should diligently adhere to the dharma taught in the Śruti and the Smṛti.
This verse does not discuss pralaya directly; it teaches the practical path to wisdom—knowledge arises through disciplined action (karma-yoga) and adherence to Vedic-traditional dharma.
It frames duty as the foundation of insight: a king or householder should perform prescribed responsibilities in a karma-yoga spirit and follow dharma grounded in Śruti and Smṛti, rather than seeking “knowledge” while neglecting righteous action.
No specific vastu/temple rule is stated; the ritual takeaway is methodological—follow rites and duties sanctioned by Śruti–Smṛti with sustained effort, since disciplined practice is presented as the means to genuine understanding.
