Matsya Purana — Marks of Karma-yoga and the Five Great Daily Sacrifices
तस्मादात्मगुणोपेतः श्रुतिकर्म समाचरेत् गोब्राह्मणानां वित्तेन सर्वदा भद्रमाचरेत् //
tasmādātmaguṇopetaḥ śrutikarma samācaret gobrāhmaṇānāṃ vittena sarvadā bhadramācaret //
Therefore, endowed with self-restraint and noble virtues, one should duly perform the duties of śruti and karma enjoined by the Veda; and with one’s wealth one should always act for the welfare of cows and Brahmins, ever doing what is auspicious and beneficial.
This verse is not about Pralaya; it focuses on dharma—performing Veda-enjoined duties and using wealth for auspicious welfare, especially supporting cows and Brahmins.
It instructs both householders and rulers to cultivate inner virtues, uphold Shruti-based obligations, and direct wealth toward public religious welfare—classically expressed as protecting and supporting go (cows) and brāhmaṇas as pillars of social and ritual order.
The ritual significance is explicit: “śruti-karma” indicates Vedic rites and prescribed duties; the verse does not mention Vastu or temple construction directly, but frames righteous resource-use as support for Vedic ritual continuity.
