premṇānuvṛttyā śīlena
 praśrayāvanatā satī
bhiyā hriyā ca bhāva-jñā
 bhartuḥ sītāharan manaḥ
Synonyms: 
premṇā anuvṛttyā — because of service rendered to the husband with love and faith; śīlena — by such good character; praśraya-avanatā — always very submissive and ready to satisfy the husband; satī — chaste; bhiyā — by being afraid; hriyā — by shyness; ca — also; bhāva-jñā — understanding the attitude (of the husband); bhartuḥ — of her husband, Lord Rāmacandra; sītā — mother Sītā; aharat — simply captivated; manaḥ — the mind.
Translation: 
Mother Sītā was very submissive, faithful, shy and chaste, always understanding the attitude of her husband. Thus by her character and her love and service she completely attracted the mind of the Lord.
Purport: 

As Lord Rāmacandra is the ideal husband (eka-patnī-vrata), mother Sītā is the ideal wife. Such a combination makes family life very happy. Yad yad ācarati śreṣṭhas tat tad evetaro janaḥ: whatever example a great man sets, common people follow. If the kings, the leaders, and the brāhmaṇas, the teachers, would set forth the examples we receive from Vedic literature, the entire world would be heaven; indeed, there would no longer be hellish conditions within this material world.

Thus end the Bhaktivedanta purports of the Ninth Canto, Tenth Chapter, of the Śrīmad-Bhāgavatam, entitled “The Pastimes of the Supreme Lord, Rāmacandra.”
