To protect the devotees, the Lord not only satisfies them by His personal presence but also teaches them so that they will not fall down from devotional service. By His personal example, Lord Rāmacandra taught the devotees that it is better not to enter married life, which is certainly followed by many tribulations. As confirmed in Śrīmad-Bhāgavatam (7.9.45):
yan maithunādi-gṛhamedhi-sukhaṁ hi tucchaṁ
kaṇḍūyanena karayor iva duḥkha-duḥkham
tṛpyanti neha kṛpaṇā bahu-duḥkha-bhājaḥ
kaṇḍūtivan manasijaṁ viṣaheta-dhīraḥ
Kṛpaṇas, those who are not advanced in spiritual knowledge and who are therefore just the opposite of brāhmaṇas, generally take to family life, which is a concession for sex. Thus they enjoy sex again and again, although that sex is followed by many tribulations. This is a warning to devotees. To teach this lesson to devotees and to human society in general, Lord Śrī Rāmacandra, although the Supreme Personality of Godhead Himself, underwent a series of tribulations because He accepted a wife, mother Sītā. Lord Rāmacandra underwent these austerities, of course, only to instruct us; actually He never has any reason to lament for anything.
(Srimad Bhagavatam-----5:19:5-----purport).

After warning the Yamadūtas not to approach the devotees, Yamarāja now indicates who is to be brought before him. He specifically advises the Yamadūtas to bring him the materialistic persons who are attached to household life merely for sex. As stated in Śrīmad-Bhāgavatam, yan maithunādi-gṛhamedhi-sukhaṁ hi tuccham: (S.B.7:9:45) people are attached to household life for sex only. They are always harassed in many ways by their material engagements, and their only happiness is that after working very hard all day, at night they sleep and indulge in sex. Nidrayā hriyate naktaṁ vyavāyena ca vā vayaḥ: (S.B.2:1:3) at night, materialistic householders sleep or indulge in sex life. Divā cārthehayā rajan kuṭumba-bharaṇena vā: during the day they are busy trying to find out where money is, and if they get money they spend it to maintain their families. Yamarāja specifically advises his servants to bring these persons to him for punishment and not to bring the devotees, who always lick the honey at the lotus feet of the Lord, who are equal to everyone, and who try to preach Kṛṣṇa consciousness because of sympathy for all living entities. Devotees are not liable to punishment by Yamarāja, but persons who have no information of Kṛṣṇa consciousness cannot be protected by their material life of so-called family enjoyment.
(Srimad Bhagavatam-----6:3:28-----purport).

Prajāpati Dakṣa wanted to prove that he had been most tolerant in not having said anything when Nārada Muni, for no reason, induced his ten thousand innocent sons to adopt the path of renunciation. Sometimes householders are accused of being gṛhamedhīs, for gṛhamedhīs are satisfied with family life without spiritual advancement. Gṛhasthas, however, are different because although gṛhasthas live in householder life with their wives and children, they are eager for spiritual advancement. Wanting to prove that he had been magnanimous to Nārada Muni, Prajāpati Dakṣa stressed that when Nārada had misled his first sons, Dakṣa had taken no action; he had been kind and tolerant. He was aggrieved, however, because Nārada Muni had misled his sons for a second time. Therefore he wanted to prove that Nārada Muni, although dressed like a sādhu, was not actually a sādhu; he himself, although a householder, was a greater sādhu than Nārada Muni.
(Srimad Bhagavatam-----6:5:42-----purport).

In household affairs the first attraction is the beautiful and pleasing wife, who increases household attraction more and more. One enjoys his wife with two prominent sense organs, namely the tongue and the genitals. The wife speaks very sweetly. This is certainly an attraction. Then she prepares very palatable foods to satisfy the tongue, and when the tongue is satisfied one gains strength in the other sense organs, especially the genitals. Thus the wife gives pleasure in sexual intercourse. Household life means sex life (yan maithunādi-gṛhamedhi-sukhaṁ hi tuccham (S.B.7:9:45). This is encouraged by the tongue. Then there are children. A baby gives pleasure by speaking sweet words in broken language, and when the sons and daughters are grown up one becomes involved in their education and marriage. Then there are one's own father and mother to be taken care of, and one also becomes concerned with the social atmosphere and with pleasing his brothers and sisters. A man becomes increasingly entangled in household affairs, so much so that leaving them becomes almost impossible. Thus the household becomes gṛham andha-kūpam, a dark well into which the man has fallen. For such a man to get out is extremely difficult unless he is helped by a strong person, the spiritual master, who helps the fallen person with the strong rope of spiritual instructions. A fallen person should take advantage of this rope, and then the spiritual master, or the Supreme Personality of Godhead, Kṛṣṇa, will take him out of the dark well.
(Srimad Bhagavatam-----7:6:11-13-----purport).

In human life there are four principles to be fulfilled-dharma, artha, kāma and mokṣa (religion, economic development, sense gratification, and liberation). First one should be religious, observing various rules and regulations, and then one must earn some money for maintenance of his family and the satisfaction of his senses. The most important ceremony for sense gratification is marriage because sexual intercourse is one of the principal necessities of the material body. Yan maithunādi-gṛhamedhi-sukhaṁ hi tuccham (S.B.7:9:45). Although sexual intercourse is not a very exalted requisite in life, both animals and men require some sense gratification because of material propensities. One should be satisfied with married life and not expend energy for extra sense gratification or sex life.
(Srimad Bhagavatam-----7:14:10-----purport).

Once one is agitated by lusty desires upon seeing a woman, those desires increase more and more, but when semen is discharged in the act of sex, the lusty desires diminish. The same principle acted upon Lord Śiva. He was allured by the beautiful woman Mohinī-mūrti, but when his semen had been fully discharged, he came to his senses and realized how he had been victimized as soon as he saw the woman in the forest. If one is trained to protect his semen by observing celibacy, naturally he is not attracted by the beauty of a woman. If one can remain a brahmacārī, he saves himself so much trouble in material existence. Material existence means enjoying the pleasure of sexual intercourse (yan maithunādi-gṛhamedhi-sukham (S.B.7:9:45). If one is educated about sex life and is trained to protect his semen, he is saved from the danger of material existence.
(Srimad Bhagavatam-----8:12:35-----purport).

In this verse, Aditi has been addressed by her husband, Kaśyapa Muni, as gṛha-medhini, which means "one who is satisfied in household life for sense gratification." Generally, those who are in household life pursue sense gratification in the field of activities performed for material results. Such gṛhamedhīs have only one aim in life—sense gratification. Therefore it is said, yan maithunādi-gṛhamedhi-sukhaṁ hi tuccham: (S.B.7:9:45) the householder's life is based on sense gratification, and therefore the happiness derived from it is very meager. Nonetheless, the Vedic process is so comprehensive that even in householder life one can adjust his activities according to the regulative principles of dharma, artha, kāma and mokṣa. One's aim should be to achieve liberation, but because one cannot at once give up sense gratification, in the śāstras there are injunctions prescribing how to follow the principles of religion, economic development and sense gratification. As explained in Śrīmad-Bhāgavatam (1.2.9), dharmasya hy āpavargyasya nārtho 'rthāyopakalpate: "All occupational engagements are certainly meant for ultimate liberation. They should never be performed for material gain." Those who are in household life should not think that religion is meant to improve the process of the householder's sense gratification. Household life is also meant for advancement in spiritual understanding, by which one can ultimately gain liberation from the material clutches. One should remain in household life with the aim of understanding the ultimate goal of life (tattva jijñāsā). Then household life is as good as the life of a yogi. Kaśyapa Muni therefore inquired from his wife whether the principles of religion, economic development and sense gratification were being properly followed in terms of the śāstric injunctions. As soon as one deviates from the injunctions of the śāstra, the purpose of household life is immediately lost in confusion.
