Husband Wife Interactions must be centered around Lord Krishna else there will be attachment

From Srila Prabhupada's purport to SB 4.28.18 where Puranjana is about to die thinking about his wife
King Purañjana was anxiously thinking, “Alas, my wife is encumbered by so many children. When I pass from this body, how will she be able to maintain all these family members? Alas, she will be greatly harassed by thoughts of family maintenance.”

All these thoughts of one’s wife indicate that the King was overly engrossed with the thoughts of woman. Generally a chaste woman becomes a very obedient wife. This causes a husband to become attached to his wife, and consequently he thinks of his wife very much at the time of death. This is a very dangerous situation, as is evident from the life of King Purañjana. If one thinks of his wife instead of Kṛṣṇa at the time of death, he will certainly not return home, back to Godhead, but will be forced to accept the body of a woman and thus begin another chapter of material existence.

From Srila Prabhupada's purport to SB 4.28.19

King Purañjana then began to think of his past dealings with his wife. He recalled that his wife would not take her dinner until he had finished his, that she would not take her bath until he had finished his, and that she was always very much attached to him, so much so that if he would sometimes become angry and chastise her, she would simply remain silent and tolerate his misbehavior.

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.

Give up family life timely to practice detachment

From Srila Prabhupada's purport to SB 4.28.3

When one reaches the age of fifty, he should give up family life. At that time one’s child should be grown up so that the father can leave the family responsibilities to him. The husband and wife may then go abroad to live a retired life and travel to different places of pilgrimage. When both the husband and wife lose their attachment for family and home, the wife returns home to live under the care of her grown-up children and to remain aloof from family affairs. The husband then takessannyāsa to render some service to the Supreme Personality of Godhead.

Sense Gratification makes the body weak and reduces life span

Srila Prabhupada's Purport 4.27.24

(Narada Muni advises KalaKanya (Jara- old age) to marry the King of the Yavanas)

The words yavanānām ṛṣabham refer to the King of the Yavanas. The Sanskrit words yavana and mleccha apply to those who do not follow the Vedic principles. According to the Vedic principles, one should rise early in the morning, take bath, chant Hare Kṛṣṇa, offer maṅgala-ārati to the Deities, study Vedic literature, take prasāda and engage in dressing and decorating the Deities. One must also collect money for the temple expenditures, or if one is a householder he must go to work in accordance with the prescribed duties of a brāhmaṇa, kṣatriya, vaiśya orśūdra. In this way one should live a life of spiritual understanding, and this is the Vedic way of civilization. One who does not follow all these rules and regulations is called a yavana or mleccha. One should not mistakenly think that these words refer to certain classes of men in other countries. There is no question of limitation according to nationalism. Whether one lives in India or outside of India, he is called a yavana or mleccha if he does not follow the Vedic principles. One who does not actually follow the hygienic principles prescribed in the Vedic rules and regulations will be subjected to many contagious diseases. Because the students in this Kṛṣṇa consciousness movement are advised to follow the Vedic principles, they naturally become hygienic.

If a person is Kṛṣṇa conscious, he can work like a young man even if he is seventy-five or eighty years old. Thus the daughter of Kāla (Time) cannot overcome a Vaiṣṇava. Śrīla Kṛṣṇadāsa Kavirāja Gosvāmī engaged in writingCaitanya-caritāmṛta when he was very old, yet he presented the most wonderful literature about the activities of Lord Caitanya. Śrīla Rūpa Gosvāmī and Sanātana Gosvāmī began their spiritual lives at a very old age — that is, after they retired from their occupations and family lives — yet they presented many valuable literatures for the advancement of spiritual life.

.......

Because a devotee rigidly follows the instructions of Nārada Muni, he has no fear of old age, disease or death. Apparently a devotee may grow old, but he is not subjected to the symptoms of defeat experienced by a common man in old age. Consequently, old age does not make a devotee fearful of death, as a common man is fearful of death. When jarā, or old age, takes shelter of a devotee, Kālakanyā diminishes the devotee’s fear. A devotee knows that after death he is going back home, back to Godhead; therefore he has no fear of death. Thus instead of depressing a devotee, advanced age helps him become fearless and thus happy.

Srila Prabhupada's purport to 4.27.28
After much consideration, the King of the Yavanas decided to make the best use of a bad bargain. Kālakanyā was a bad bargain, and no one liked her, but everything can be used for the service of the Lord. Thus the King of the Yavanas tried to utilize her for some purpose. The purpose has already been explained — that is, Kālakanyā asjarā, the invalidity of old age, can be used to arouse a sense of fear in people so that they will prepare for the next life by engaging in Kṛṣṇa consciousness.


Foolish people accept unhappiness as happiness; therefore the King of the Yavanas decided to attack such foolish people imperceptibly by old age, disease, and ultimately death. Of course, after death there must be birth; therefore Yavana-rāja thought it wise to kill all the karmīs through the agency of Kālakanyā and thus try to make them aware that materialistic advancement is not actually advancement. Every living entity is a spiritual being, and consequently without spiritual advancement the human form of life is ruined.

Srila Prabhupada's purport to 4.27.30

Yavana-rāja’s brother was Prajvāra, and Kālakanyā was invalidity itself. Combined and strengthened by the soldiers of Yavana-rāja — namely nonhygienic conditions, illicit sex and ultimately a high degree of temperature to bring on death — they would be able to smash the materialistic way of life. In this connection it is significant that Nārada was immune to the attack of jarā, or invalidity. Similarly jarā,or the destructive force, cannot attack any follower of Nārada Muni or another pure Vaiṣṇava.

Srila Prabhupada's purport to 4.28.2
According to the Vedic system, before coming to such a stage one should leave home and take sannyāsa to preach the message of God for the duration of life. However, if one sits at home and is served by his beloved wife and children, he certainly becomes weaker and weaker due to sense gratification. When death finally comes, one leaves the body devoid of spiritual assets.

Sexual Addiction reduces life span, intelligence, opulence and personal beauty

Srila Prabhupada's Purport to 4.27.21

The great sage Nārada Muni was a naiṣṭhika-brahmacārī — that is, he never had sex life. He was consequently an ever-green youth. Old age, jarā, could not attack him. The invalidity of old age can overcome an ordinary man, but Nārada Muni was different. Taking Nārada Muni to be an ordinary man, the daughter of Time confronted him with her lusty desire. It requires great strength to resist a woman’s attraction. It is difficult for old men, and what to speak of young. Those who live as brahmacārīs must follow in the footsteps of the great sage Nārada Muni, who never accepted the proposals of Jarā. Those who are too much sexually addicted become victims of jarā, and very soon their life span is shortened. Without utilizing the human form of life for Kṛṣṇa consciousness, the victims ofjarā die very soon in this world.

Srila Prabhupada's purport to 4.28.1

When a man is young, he does not care for old age but enjoys sex to the best of his satisfaction, not knowing that at the end of life his sexual indulgence will bring on various diseases, which so much disturb the body that one will pray for immediate death. The more one enjoys sex during youth, the more he suffers in old age.

SB 4.28.6: 

When King Purañjana was embraced by Kālakanyā, he gradually lost all his beauty. Having been too much addicted to sex, he became very poor in intelligence and lost all his opulence. Being bereft of all possessions, he was conquered forcibly by the Gandharvas and the Yavanas.

Purport: 

When a person is attacked by the invalidity of old age and is still addicted to sense gratification, he gradually loses all his personal beauty, intelligence and good possessions. He thus cannot resist the forceful attack of the daughter of Time.
