Matsya Purana — Marks of Karma-yoga and the Five Great Daily Sacrifices
*ऋषय ऊचुः श्रोतुमिच्छामहे सूत कर्मयोगस्य लक्षणम् यस्मादविदितं लोके न किंचित्तव सुव्रत //
*ṛṣaya ūcuḥ śrotumicchāmahe sūta karmayogasya lakṣaṇam yasmādaviditaṃ loke na kiṃcittava suvrata //
The sages said: “O Sūta, we wish to hear the defining characteristics of karma-yoga; for in this world nothing is unknown to you, O man of excellent vows.”
This verse does not discuss pralaya directly; it introduces a doctrinal inquiry—requesting the marks of karma-yoga—showing the text’s ethical emphasis rather than cosmology in this moment.
By asking for the ‘lakṣaṇa’ of karma-yoga, the sages set up guidance for right action performed as duty—precisely the framework used in Purāṇic dharma for rulers and householders: acting responsibly without selfish attachment.
No vastu/temple-architecture rule is stated in this verse; its ritual significance is indirect—karma-yoga commonly includes performing rites and duties with the correct inner attitude (discipline and selflessness).
