As chaste women bring their gentle husbands under control by service, the pure devotees, who are equal to everyone and completely attached to Me in the core of the heart, bring Me under their full control.
In this verse, the word sama-darśanāḥ is significant. The pure devotee is actually equal toward everyone, as confirmed in Bhagavad-gītā (18.54): brahma-bhūtaḥ prasannātmā na śocati na kāṅkṣati/ samaḥ sarveṣu bhūteṣu. Universal brotherhood is possible when one is a pure devotee (paṇḍitāḥ sama-darśinaḥ (B.G.5:18). A pure devotee is actually learned because he knows his constitutional position, he knows the position of the Supreme Personality of Godhead, and he knows the relationship between the living entity and the Supreme Lord. Thus he has full spiritual knowledge and is automatically liberated (brahma-bhūtaḥ). He can therefore see everyone on the spiritual platform. He can comprehend the happiness and distress of all living entities. He understands that what is happiness to him is also happiness to others and that what is distress to him is distressing for others. Therefore he is sympathetic to everyone. As Prahlāda Mahārāja said:
śoce tato vimukha-cetasa indriyārtha-
māyā-sukhāya bharam udvahato vimūḍhān
(S.B.7:9:43)
People suffer from material distress because they are not attached to the Supreme Personality of Godhead. A pure devotee's chief concern, therefore, is to raise the ignorant mass of people to the sense of Kṛṣṇa consciousness.
(Srimad Bhagavatam------9:4:66-----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).

It is quite clear that according to Vedic culture a woman who accepts a paramour or second husband in the presence of the husband she has married is certainly responsible for the degradation of her father's family and the family of her husband. The rules of Vedic culture in this regard are strictly observed in the respectable families of brāhmaṇas, kṣatriyas and vaiśyas even today; only the śūdras are degraded in this matter. For a woman of the brāhmaṇa, kṣatriya or vaiśya class to accept another husband in the presence of the husband she has married, or to file for divorce or accept a boyfriend or paramour, is unacceptable in the Vedic culture.
(Srimad Bhagavatam------9:3:21-----purport).

Cyavana Muni was very irritable, but since Sukanyā had gotten him as her husband, she dealt with him carefully, according to his mood. Knowing his mind, she performed service to him without being bewildered.
This is an indication of the relationship between husband and wife. A great personality like Cyavana Muni has the temperament of always wanting to be in a superior position. Such a person cannot submit to anyone. Therefore, Cyavana Muni had an irritable temperament. His wife, Sukanyā, could understand his attitude, and under the circumstances she treated him accordingly. If any wife wants to be happy with her husband, she must try to understand her husband's temperament and please him. This is victory for a woman. Even in the dealings of Lord Kṛṣṇa with His different queens, it has been seen that although the queens were the daughters of great kings, they placed themselves before Lord Kṛṣṇa as His maidservants. However great a woman may be, she must place herself before her husband in this way; that is to say, she must be ready to carry out her husband's orders and please him in all circumstances. Then her life will be successful. When the wife becomes as irritable as the husband, their life at home is sure to be disturbed or ultimately completely broken. In the modern day, the wife is never submissive, and therefore home life is broken even by slight incidents. Either the wife or the husband may take advantage of the divorce laws. According to the Vedic law, however, there is no such thing as divorce laws, and a woman must be trained to be submissive to the will of her husband. Westerners contend that this is a slave mentality for the wife, but factually it is not; it is the tactic by which a woman can conquer the heart of her husband, however irritable or cruel he may be. In this case we clearly see that although Cyavana Muni was not young but indeed old enough to be Sukanyā's grandfather and was also very irritable, Sukanyā, the beautiful young daughter of a king, submitted herself to her old husband and tried to please him in all respects. Thus she was a faithful and chaste wife.
(Srimad Bhagavatam------9:3:10-----translation and purport).

Upon Kaṁsa's death, his two wives became widows. According to Vedic civilization, a woman is never independent. She has three stages of life: in childhood a woman should live under the protection of her father, a youthful woman should live under the protection of her young husband, and in the event of the death of her husband she should live under the protection of her grown-up sons, or if she has no grown-up sons she must go back to her father and live as a widow under his protection. It appears that Kaṁsa had no grown-up sons. Therefore, after his wives became widows they returned to the shelter of their father. Kaṁsa had two queens, Asti and Prāpti, and both happened to be the daughters of King Jarāsandha, the lord of the Bihar Province (known in those days as Magadha). After reaching home, the two queens explained their awkward position following Kaṁsa's death. The King of Magadha, Jarāsandha, was mortified on hearing of the pitiable condition of his daughters. When informed of the death of Kaṁsa, Jarāsandha decided on the spot that he would rid the world of all the members of the Yadu dynasty. He decided that since Kṛṣṇa had killed Kaṁsa, the whole dynasty of the Yadus should be killed.
(Krsna Book).

Working sanely and diligently, she pleased her very powerful husband, giving up all lust, pride, envy, greed, sinful activities and vanity.
Here are some of the qualities of a great husband's great wife. Kardama Muni is great by spiritual qualification. Such a husband is called tejīyāṁsam, most powerful. Although a wife may be equal to her husband in advancement in spiritual consciousness, she should not be vainly proud. Sometimes it happens that the wife comes from a very rich family, as did Devahūti, the daughter of Emperor Svāyambhuva Manu. She could have been very proud of her parentage, but that is forbidden. The wife should not be proud of her parental position. She must always be submissive to the husband and must give up all vanity. As soon as the wife becomes proud of her parentage, her pride creates great misunderstanding between the husband and wife, and their nuptial life is ruined. Devahūti was very careful about that, and therefore it is said here that she gave up pride completely. Devahūti was not unfaithful. The most sinful activity for a wife is to accept another husband or another lover. Cāṇakya Paṇḍita has described four kinds of enemies at home. If the father is in debt he is considered to be an enemy; if the mother has selected another husband in the presence of her grown-up children, she is considered to be an enemy; if a wife does not live well with her husband but deals very roughly, then she is an enemy; and if a son is a fool, he is also an enemy. In family life, father, mother, wife and children are assets, but if the wife or mother accepts another husband in the presence of her husband or son, then, according to Vedic civilization, she is considered an enemy. A chaste and faithful woman must not practice adultery—that is a greatly sinful act.
(Srimad Bhagavatam------3:23:3-----translation and purport).

An ideal husband and wife are generally called Lakṣmī-Nārāyaṇa to compare them to the Lord and the goddess of fortune, for it is significant that Lakṣmī-Nārāyaṇa are forever happy as husband and wife. A wife should always remain satisfied with her husband, and a husband should always remain satisfied with his wife. In the Cāṇakya-śloka, the moral instructions of Cāṇakya Paṇḍita, it is said that if a husband and wife are always satisfied with one another, then the goddess of fortune automatically comes. In other words, where there is no disagreement between husband and wife, all material opulence is present, and good children are born. Generally, according to Vedic civilization, the wife is trained to be satisfied in all conditions, and the husband, according to Vedic instruction, is required to please the wife with sufficient food, ornaments and clothing. Then, if they are satisfied with their mutual dealings, good children are born. In this way the entire world can become peaceful, but unfortunately in this age of Kali there are no ideal husbands and wives; therefore unwanted children are produced, and there is no peace and prosperity in the present-day world.
(Srimad Bhagavatam------4:1:6-----purport).

A wife is always supposed to be submissive to her husband. Submission, mild behavior and subservience are qualities in a wife which make a husband very thoughtful of her. For family life it is very good for a husband to be attached to his wife, but it is not very good for spiritual advancement. Thus Kṛṣṇa consciousness must be established in every home. If a husband and wife are very much attached to one another in Kṛṣṇa consciousness, they will both benefit because Kṛṣṇa is the center of their existence. Otherwise, if the husband is too much attached to his wife, he becomes a woman in his next life. The woman, being overly attached to her husband, becomes a man in her next life. Of course, it is an advantage for a woman to become a man, but it is not at all advantageous for the man to become a woman.
