Matsya Purana — Marks of Karma-yoga and the Five Great Daily Sacrifices
न च द्रव्येषु कार्पण्यम् आर्तेषूपार्जितेषु च तथास्पृहा परद्रव्ये परस्त्रीषु च सर्वदा //
na ca dravyeṣu kārpaṇyam ārteṣūpārjiteṣu ca tathāspṛhā paradravye parastrīṣu ca sarvadā //
One should not be miserly with one’s wealth—especially with wealth acquired for the relief of the distressed; and one should always remain free from craving for another’s property and for another’s wife.
This verse does not discuss pralaya; it focuses on dharmic self-restraint—generosity with one’s wealth and non-covetousness toward others’ possessions and spouses.
It frames core duties of rulers and householders: do not hoard wealth, especially when it should relieve the distressed, and maintain strict restraint by not desiring others’ property or wives—key pillars of social order and righteous governance.
No vastu/temple-building or ritual procedure is mentioned; the significance is ethical—purity of conduct and responsible use of wealth, which underpins merit in all religious and social acts.
