The word viraktimat in this verse means "possessed of the qualification of renunciation." Spiritual realization cannot be attained by materialistic persons. For those who are addicted to sense enjoyment, spiritual realization is not possible. In Bhagavad-gītā it is stated that those who are too attached to seeking material possessions and material enjoyment cannot reach yoga-samādhi, absorption in Kṛṣṇa consciousness. Propaganda that one can enjoy this life materially and at the same time spiritually advance is simply bogus. The principles of renunciation are four: (1) to avoid illicit sex life, (2) to avoid meat-eating, (3) to avoid intoxication and (4) to avoid gambling. These four principles are called tapasya, or austerity. To absorb the mind in the Supreme in Kṛṣṇa consciousness is the process of spiritual realization.
(Srimad Bhagavatam-------3:20:53---------purport).

Men and women whose lives were built upon indulgence in illicit sex life are put into many kinds of miserable conditions in the hells known as Tāmisra, Andha-tāmisra and Raurava.
Materialistic life is based on sex life. The existence of all the materialistic people, who are undergoing severe tribulation in the struggle for existence, is based on sex. Therefore, in the Vedic civilization sex life is allowed only in a restricted way; it is for the married couple and only for begetting children. But when sex life is indulged in for sense gratification illegally and illicitly, both the man and the woman await severe punishment in this world or after death. In this world also they are punished by virulent diseases like syphilis and gonorrhea, and in the next life, as we see in this passage of Śrīmad-Bhāgavatam, they are put into different kinds of hellish conditions to suffer. In Bhagavad-gītā, First Chapter, illicit sex life is also very much condemned, and it is said that one who produces children by illicit sex life is sent to hell. It is confirmed here in the Bhāgavatam that such offenders are put into hellish conditions of life in Tāmisra, Andha-tāmisra and Raurava.

(Srimad Bhagavatam-------3:30:28---------translation and purport).

A devotee is not concerned with enjoyment or distress; he simply desires to execute devotional service. It is said in the Śrīmad-Bhāgavatam that devotional service should be apratihatā, unchecked by the material conditions of happiness or distress. The devotee undergoes processes of austerity such as observing Ekādaśī and similar other fasting days and refraining from illicit sex life, intoxication, gambling and meat-eating. Thus he becomes purified from the reactions of his past impious life, and because he engages in devotional service, which is the most pious activity, he enjoys life without separate endeavor.

(Srimad Bhagavatam-------4:12:13---------purport).

By the regular performance of yajña, the equal distribution of wealth and the restriction of sense gratification, the entire world will be made peaceful and prosperous. As already mentioned, in this age of Kali the simple performance of saṅkīrtana-yajña—the holding of festivals as initiated by the International Society for Krishna Consciousness—should be introduced in every town and village. Intelligent men should encourage the performance of saṅkīrtana-yajña by their personal behavior. This means that they should follow the process of austerity by restricting themselves from illicit sex life, meat-eating, gambling and intoxication. If the intelligent men, or the brāhmaṇas of society, would follow the rules and regulations, certainly the entire face of this present world, which is in such chaotic condition, would change, and people would be happy and prosperous.
(Srimad Bhagavatam-------4:18:13---------purport).

The greatest calamity in life is to become godless and therefore sinful. If the state head or king allows the citizens to become sinful by indulging in illicit sex life, intoxication, meat-eating and gambling, then the king is responsible, and he has to suffer the resultant sequence of reactions for the sinful lives of the citizens because he levies taxes on them unnecessarily. These are the principles for a ruling power, and because Mahārāja Pṛthu observed all the principles for a ruling chief, he is referred to here as ādi-rājaḥ.
(Srimad Bhagavatam-------4:20:21---------purport).

To do what is good means to accept everything favorable to the discharge of devotional service, and to reject what is not good means to reject everything not favorable for discharging devotional service. In our Kṛṣṇa consciousness movement, we accept this principle by rejecting four prohibited items—namely illicit sex life, intoxication, gambling and flesh—eating—and accepting the daily chanting of at least sixteen rounds of the Hare Kṛṣṇa mahā-mantra and daily meditation three times a day by chanting the Gāyatrī mantra. In this way one can keep his brahminical culture and spiritual strength intact.
(Srimad Bhagavatam-------4:21:42---------purport).

Actually everyone is suffering within this material world due to ignorance. Every day we see that a person without knowledge commits some criminal act and is later arrested and punished, despite the fact that he actually may not have been conscious of his sinful activity. Such ignorance prevails throughout the world. People do not consider how they are risking their lives in an attempt to have illicit sex life, kill animals to satisfy their tongue, enjoy intoxication and gamble. It is very regrettable that the leaders of the world do not know of the effects of these sinful activities. They are instead taking things very easily and are succeeding in making the ocean of nescience wider and wider.
(Srimad Bhagavatam-------4:24:75---------purport).

On the whole, for spiritual advancement, one must give up the company of women. This is what is meant by the order of sannyāsa, the renounced order. Before taking sannyāsa, or completely renouncing the material world, one has to practice avoiding illicit sex. Sex life, licit or illicit, is practically the same, but through illicit sex one becomes more and more captivated. By regulating one's sex life there is a chance that one may eventually be able to renounce sex or renounce the association of women. If this can be done, advancement in spiritual life comes very easily.
(Srimad Bhagavatam-------4:25:62---------purport).

When a man comes in contact with a saintly person, he becomes aware of the stringent laws of nature and thus becomes a religious person. Irreligious persons are like animals, but in this Kṛṣṇa consciousness movement such persons can come to a sense of understanding things as they are and abandon the four principles of prohibited activities—namely illicit sex life, meat-eating, gambling and intoxication. This is the beginning of religious life. Those who are so-called religious and indulge in these four principles of prohibited activities are pseudo-religionists. Religious life and sinful activity cannot parallel one another.
(Srimad Bhagavatam-------4:26:10---------purport).

Sons and daughters should not be allowed freedom to intermingle with the opposite sex unless they are married. This Vedic social organization is very good in that it stops the promulgation of illicit sex life, or varṇa-saṅkara, which appears under different names in this present day. Unfortunately in this age although the father and mother are anxious to get their children married, the children refuse to get married by the arrangement of the parents. Consequently, the number of varṇa-saṅkara has increased throughout the world under different names.
(Srimad Bhagavatam-------4:27:8---------purport).

Generally a man should not have sexual relations with any woman other than his wife. According to Vedic principles, the wife of another man is considered one's mother, and sexual relations are strictly forbidden with one's mother, sister and daughter. If one indulges in illicit sexual relations with another man's wife, that activity is considered identical with having sex with one's mother. This act is most sinful. The same principle holds for a woman also; if she enjoys sex with a man other than her husband, the act is tantamount to having sexual relations with her father or son. Illicit sex life is always forbidden, and any man or woman who indulges in it is punished in the manner described in this verse.
(Srimad Bhagavatam-------5:26:20---------purport).
