The popular saying is that a housewife teaches the daughter-in-law by teaching the daughter. Similarly, the Lord teaches the world by teaching the devotee. The devotee does not have to learn anything new from the Lord because the Lord teaches the sincere devotee always from within. Whenever, therefore, a show is made to teach the devotee, as in the case of the teachings of Bhagavad-gītā, it is for teaching the less intelligent men. A devotee's duty, therefore, is to ungrudgingly accept tribulations from the Lord as a benediction.
(Srimad Bhagavatam--------1:9:17--------purport).

The words bhartur vrata-dharma-niṣṭhayā indicate that a woman's duty, or religious principle, is to serve her husband in all conditions. In Vedic civilization a man is taught from the beginning of his life to become a brahmacārī, then an ideal gṛhastha, then vānaprastha, then sannyāsī, and the wife is taught just to follow the husband strictly in all conditions of life. After the period of brahmacarya, a man accepts a householder's life, and the woman is also taught by her parents to be a chaste wife. Thus when a girl and boy are united, both are trained for a life dedicated to a higher purpose. The boy is trained to execute his duty in accordance with the higher purpose of life, and the girl is trained to follow him. The chaste wife's duty is to keep her husband pleased in householder life in all respects, and when the husband retires from family life, she is to go to the forest and adopt the life of vānaprastha, or vana-vāsī. At that time the wife is to follow her husband and take care of him, just as she took care of him in householder life. But when the husband takes the renounced order of life, namely sannyāsa, the wife is to return home and become a saintly woman, setting an example for her children and daughters-in-law and showing them how to live a life of austerity.
