A chaste woman should not be greedy, but satisfied in all circumstances. She must be very expert in handling household affairs and should be fully conversant with religious principles. She should speak pleasingly and truthfully and should be very careful and always clean and pure. Thus a chaste woman should engage with affection in the service of a husband who is not fallen.
According to the injunction of Yājñavalkya, an authority on religious principles, āśuddheḥ sampratikṣyo hi mahāpātaka-dūṣitaḥ. One is considered contaminated by the reactions of great sinful activities when one has not been purified according to the methods of the daśa-vidhā-saṁskāra. In Bhagavad-gītā, however, the Lord says, na māṁ duṣkṛtino mūḍhāḥ prapadyante narādhamāḥ: (B.G.7:15) "Those miscreants who do not surrender unto Me are the lowest of mankind." The word narādhama means "nondevotee." Śrī Caitanya Mahāprabhu also said, yei bhaje sei baḍa, abhakta-hīna (CC.3:4:67), chāra. Anyone who is a devotee is sinless. One who is not a devotee, however, is the most fallen and condemned. It is recommended, therefore, that a chaste wife not associate with a fallen husband. A fallen husband is one who is addicted to the four principles of sinful activity—namely illicit sex, meat-eating, gambling and intoxication. Specifically, if one is not a soul surrendered to the Supreme Personality of Godhead, he is understood to be contaminated. Thus a chaste woman is advised not to agree to serve such a husband. It is not that a chaste woman should be like a slave while her husband is narādhama, the lowest of men. Although the duties of a woman are different from those of a man, a chaste woman is not meant to serve a fallen husband. If her husband is fallen, it is recommended that she give up his association. Giving up the association of her husband does not mean, however, that a woman should marry again and thus indulge in prostitution. If a chaste woman unfortunately marries a husband who is fallen, she should live separately from him. Similarly, a husband can separate himself from a woman who is not chaste according to the description of the śāstra. The conclusion is that a husband should be a pure Vaiṣṇava and that a woman should be a chaste wife with all the symptoms described in this regard. Then both of them will be happy and make spiritual progress in Kṛṣṇa consciousness.
(Srimad Bhagavatam-----7:11:28----translation and -purport).

A chaste woman will never accept any man other than her husband, even if there be someone equally as handsome and qualified.
(Srimad Bhagavatam-----9:3:16-----purport).

A woman is generally accustomed to dress herself nicely with fine garments and decorative ornaments. She may even sometimes wear flowers in her hair. Women especially dress themselves up in the evening because the husband comes home in the evening after working hard all day. It is the duty of the wife to dress herself up very nicely so that when her husband returns home he becomes attracted by her dress and cleanliness and thus becomes satisfied. In other words, the wife is the inspiration of all good intelligence. Upon seeing one's wife dressed nicely, one can think very soberly about family business. When a person is too anxious about family affairs, he cannot discharge his family duties nicely. A wife is therefore supposed to be an inspiration and should keep the husband's intelligence in good order so that they can combinedly prosecute the affairs of family life without impediment.
(Srimad Bhagavatam-----4:27:2-----purport).

“"When a husband is fallen, one"s relationship with him must be given up.’”
This is a quotation from the smṛti-śāstra. As stated in Śrīmad-Bhāgavatam (7.11.28):
santuṣṭālolupā dakṣā dharma-jñā priya-satya-vāk
apramattā śuciḥ snigdhā patiṁ tv apatitaṁ bhajet
"A wife who is satisfied, who is not greedy, who is expert and knows religious principles, who speaks what is dear and truthful and is not bewildered, and who is always clean and affectionate should be very much devoted to her husband if he is not fallen."
(Sri Caitanya Caritamrta-----2:15:265-----translation and purport).

A living entity who, as a result of attachment to a woman in his previous life, has been endowed with the form of a woman, foolishly looks upon māyā in the form of a man, her husband, as the bestower of wealth, progeny, house and other material assets.
From this verse it appears that a woman is also supposed to have been a man in his (her) previous life, and due to his attachment to his wife, he now has the body of a woman. Bhagavad-gītā confirms this; a man gets his next life's birth according to what he thinks of at the time of death. If someone is too attached to his wife, naturally he thinks of his wife at the time of death, and in his next life he takes the body of a woman. Similarly, if a woman thinks of her husband at the time of death, naturally she gets the body of a man in the next life. In the Hindu scriptures, therefore, woman's chastity and devotion to man is greatly emphasized. A woman's attachment to her husband may elevate her to the body of a man in her next life, but a man's attachment to a woman will degrade him, and in his next life he will get the body of a woman. We should always remember, as it is stated in Bhagavad-gītā, that both the gross and subtle material bodies are dresses; they are the shirt and coat of the living entity. To be either a woman or a man only involves one's bodily dress. The soul in nature is actually the marginal energy of the Supreme Lord. Every living entity, being classified as energy, is supposed to be originally a woman, or one who is enjoyed. In the body of a man there is a greater opportunity to get out of the material clutches; there is less opportunity in the body of a woman. In this verse it is indicated that the body of a man should not be misused through forming an attachment to women and thus becoming too entangled in material enjoyment, which will result in getting the body of a woman in the next life. A woman is generally fond of household prosperity, ornaments, furniture and dresses. She is satisfied when the husband supplies all these things sufficiently. The relationship between man and woman is very complicated, but the substance is that one who aspires to ascend to the transcendental stage of spiritual realization should be very careful in accepting the association of a woman. In the stage of Kṛṣṇa consciousness, however, such restriction of association may be slackened because if a man's and woman's attachment is not to each other but to Kṛṣṇa, then both of them are equally eligible to get out of the material entanglement and reach the abode of Kṛṣṇa. As it is confirmed in Bhagavad-gītā, anyone who seriously takes to Kṛṣṇa consciousness—whether in the lowest species of life or a woman or of the less intelligent classes, such as the mercantile or laborer class—will go back home, back to Godhead, and reach the abode of Kṛṣṇa. A man should not be attached to a woman, nor should a woman be attached to a man. Both man and woman should be attached to the service of the Lord. Then there is the possibility of liberation from material entanglement for both of them.
(Sri Caitanya Caritamrta-----3:31:41-----translation and 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.
When Caitanya Mahāprabhu took sannyāsa, His wife, Viṣṇupriyādevī, although only sixteen years old, also took the vow of austerity due to her husband's leaving home. She chanted her beads, and after finishing one round, she collected one grain of rice. In this way, as many rounds as she chanted, she would receive the same number of rice grains and then cook them and so take prasāda. This is called austerity. Even today in India, widows or women whose husbands have taken sannyāsa follow the principles of austerity, even though they live with their children. Pṛthu Mahārāja's wife, Arci, was steadily determined to execute the duty of a wife, and while her husband was in the forest, she followed him in eating only fruits and leaves and lying down on the ground. Since a woman's body is considerably more delicate than a man's, Queen Arci became very frail and thin, parikarśitā. When one engages in austerities, his body generally becomes lean and thin. Becoming fat is not a very good qualification in spiritual life because a person who is engaged in spiritual life must reduce the comforts of the body—namely eating, sleeping and mating—to a minimum. Although Queen Arci became very thin from living in the forest according to regulative principles, she was not unhappy, for she was enjoying the honor of serving her great husband.
(Srimad Bhagavatam-----4:23:20-----purport).

O Vidura, Devahūti served her husband with intimacy and great respect, with control of the senses, with love and with sweet words.
Here two words are very significant. Devahūti served her husband in two ways, viśrambheṇa and gauraveṇa. These are two important processes in serving the husband or the Supreme Personality of Godhead. Viśrambheṇa means "with intimacy," and gauraveṇa means "with great reverence." The husband is a very intimate friend; therefore, the wife must render service just like an intimate friend, and at the same time she must understand that the husband is superior in position, and thus she must offer him all respect. A man's psychology and woman's psychology are different. As constituted by bodily frame, a man always wants to be superior to his wife, and a woman, as bodily constituted, is naturally inferior to her husband. Thus the natural instinct is that the husband wants to post himself as superior to the wife, and this must be observed. Even if there is some wrong on the part of the husband, the wife must tolerate it, and thus there will be no misunderstanding between husband and wife. Viśrambheṇa means "with intimacy," but it must not be familiarity that breeds contempt. According to the Vedic civilization, a wife cannot call her husband by name. In the present civilization the wife calls her husband by name, but in Hindu civilization she does not. Thus the inferiority and superiority complexes are recognized. Damena ca: a wife has to learn to control herself even if there is a misunderstanding. Sauhṛdena vācā madhurayā means always desiring good for the husband and speaking to him with sweet words. A person becomes agitated by so many material contacts in the outside world; therefore, in his home life he must be treated by his wife with sweet words.
(Srimad Bhagavatam-----3:23:2-----purport).

According to the Vedic conception of family life, the husband gives half his body to his wife, and the wife gives half of her body to her husband. In other words, a husband without a wife or a wife without a husband is incomplete. Vedic marital relationship existed between Lord Śiva and Satī, but sometimes, due to weakness, a woman becomes very much attracted by the members of her father's house, and this happened to Satī. In this verse it is specifically mentioned that she wanted to leave such a great husband as Śiva because of her womanly weakness. In other words, womanly weakness exists even in the relationship between husband and wife. Generally, separation between husband and wife is due to womanly behavior; divorce takes place due to womanly weakness. The best course for a woman is to abide by the orders of her husband. That makes family life very peaceful. Sometimes there may be misunderstandings between husband and wife, as found even in such an elevated family relationship as that of Satī and Lord Śiva, but a wife should not leave her husband's protection because of such a misunderstanding. If she does so, it is understood to be due to her womanly weakness.
