मनुस्मृति - स्त्री सौख्य

शोचन्ति चामयो यत्र विनश्यत्याशु तत्कुलम् |
न शोचन्ति तु यत्रैता वर्धते तद्धि सर्वदा ||

- मनुस्मृति

If the women of the house are in distress (due to oppression) then that family will surely be destroyed. If they are not oppressed (and hence happy) then such a family surely prosper.

- Manu Smriti
