मनुस्मृति - स्त्रीरत्न

श्रद्धधानः शुभां विद्यामाददीतावरादपि ।
अंत्यादपि परं धर्मं स्त्रीरत्नं दुष्कुलादपि ॥

- manusmriti

One must have good dedication even when learning from a person younger than him. One must be open to learn subtleties of Dharma from any one. One should bring a virtuous lady into home (as daughter-in-law) even if she is from bad family.
