SB Canto 1

As soon as a male is combined with a female, the material bondage of the living being is at once tightly interlocked by sex relation, and as a result of this, both the male's and female's attraction for sweet home, motherland, bodily offspring, society and friendship and accumulation of wealth becomes the illusory field of activities, and thus a false but indefatigable attraction for the temporary material existence, which is full of miseries, is manifest.

SB 1.11.36, Translation and Purport:

Although the queens' beautiful smiles and furtive glances were all spotless and exciting, and although they could conquer Cupid himself by making him give up his bow in frustration, and although even the tolerant Śiva could fall victim to them, still, despite all their magical feats and attractions, they could not agitate the senses of the Lord.

The path of salvation or the path going back to Godhead always forbids the association of women, and the complete sanātana-dharma or varṇāśrama-dharma scheme forbids or restricts association with women. How, then, can one be accepted as the Supreme Personality of Godhead who is addicted to more than sixteen thousand wives? This question may be relevantly raised by inquisitive persons really anxious to know about the transcendental nature of the Supreme Lord. And to answer such questions, the sages at Naimiṣāraṇya have discussed the transcendental character of the Lord in this and in following verses. It is clear herein that the feminine attractive features which can conquer Cupid or even the supermost tolerant Lord Śiva could not conquer the senses of the Lord. Cupid's business is to invoke mundane lust. The whole universe is moving being agitated by Cupid's arrow. The activities of the world are being carried on by the central attraction of male and female. A male is searching after a mate to his liking, and the female is looking after a suitable male. That is the way of material stimulus. And as soon as a male is combined with a female, the material bondage of the living being is at once tightly interlocked by sex relation, and as a result of this, both the male's and female's attraction for sweet home, motherland, bodily offspring, society and friendship and accumulation of wealth becomes the illusory field of activities, and thus a false but indefatigable attraction for the temporary material existence, which is full of miseries, is manifest. Those who are, therefore, on the path of salvation for going back home back to Godhead, are especially advised by all scriptural instruction to become free from such paraphernalia of material attraction. And that is possible only by the association of the devotees of the Lord, who are called the mahātmās. Cupid throws his arrow upon the living beings to make them mad after the opposite sex, whether the party is actually beautiful or not. Cupid's provocations are going on, even among beastly societies who are all ugly-looking in the estimation of the civilized nations. Thus Cupid's influence is exerted even amongst the ugliest forms, and what to speak of the most perfect beauties. Lord Śiva, who is considered to be most tolerant, was also struck by Cupid's arrow because he also became mad after the Mohinī incarnation of the Lord and acknowledged himself to be defeated. Cupid, however, was himself captivated by the grave and exciting dealings of the goddesses of fortune, and he voluntarily gave up his bow and arrow in a spirit of frustration. Such was the beauty and attraction of the queens of Lord Kṛṣṇa. Yet they could not disturb the transcendental senses of the Lord. This is because the Lord is all-perfect ātmārāma, or self-sufficient. He does not require anyone's extraneous help for His personal satisfaction. Therefore, the queens could not satisfy the Lord by their feminine attractiveness, but they satisfied Him by their sincere affection and service. Only by unalloyed transcendental loving service could they satisfy the Lord, and the Lord was pleased to treat them as wives in reciprocation. Thus being satisfied by their unalloyed service only, the Lord reciprocated the service just like a devout husband. Otherwise He had no business becoming the husband of so many wives. He is the husband of everyone, but to one who accepts Him as such, He reciprocates. This unalloyed affection for the Lord is never to be compared to mundane lust. It is purely transcendental. And the grave dealings, which the queens displayed in natural feminine ways, were also transcendental because the feelings were expressed out of transcendental ecstasy. It is already explained in the previous verse that the Lord appeared like a mundane husband, but factually His relation with His wives was transcendental, pure and unconditioned by the modes of material nature.

SB Canto 2

When the male and female are united, the sex desire is further aggravated by the accumulation of buildings, children, friends, relatives and wealth. When all these are acquired, the conditioned soul becomes overwhelmed by such entanglements, and the false sense of egoism, or the sense of "myself" and "mine," becomes prominent, and the sex desire expands to various political, social, altruistic, philanthropic and many other unwanted engagements, resembling the foam of the sea waves, which becomes very prominent at one time and at the next moment vanishes as quickly as a cloud in the sky.

SB 2.2.12, Translation and Purport:

The Lord's magnanimous pastimes and the glowing glancing of His smiling face are all indications of His extensive benedictions. One must therefore concentrate on this transcendental form of the Lord, as long as the mind can be fixed on Him by meditation.

In Bhagavad-gītā (12.5) it is said that the impersonalist undergoes a series of difficult programs on account of his impersonal meditation. But the devotee, due to the Lord's personal service, progresses very easily. Impersonal meditation is therefore a source of suffering for the impersonalist. Here, the devotee has an advantage over the impersonalist philosopher. The impersonalist is doubtful about the personal feature of the Lord, and therefore he always tries to meditate upon something which is not objective. For this reason there is an authentic statement in the Bhāgavatam regarding the positive concentration of the mind on the factual form of the Lord.

The process of meditation recommended herein is bhakti-yoga, or the process of devotional service after one is liberated from the material conditions. Jñāna-yoga is the process of liberation from the material conditions. After one is liberated from the conditions of material existence, i.e., when one is nivṛtta, as previously stated herein, or when one is freed from all material necessities, one becomes qualified to discharge the process of bhakti-yoga. Therefore bhakti-yoga includes jñāna-yoga, or, in other words, the process of pure devotional service simultaneously serves the purpose of jñāna-yoga; liberation from material conditions is automatically achieved by the gradual development of pure devotional service. These effects of bhakti-yoga are called anartha-nivṛtti. Things which are artificially acquired gradually disappear along with the progress of bhakti-yoga. Meditation on the lotus feet of the Personality of Godhead, the first processional step, must show its effect by anartha-nivṛtti. The grossest type of anartha which binds the conditioned soul in material existence is sex desire, and this sex desire gradually develops in the union of the male and female. When the male and female are united, the sex desire is further aggravated by the accumulation of buildings, children, friends, relatives and wealth. When all these are acquired, the conditioned soul becomes overwhelmed by such entanglements, and the false sense of egoism, or the sense of "myself" and "mine," becomes prominent, and the sex desire expands to various political, social, altruistic, philanthropic and many other unwanted engagements, resembling the foam of the sea waves, which becomes very prominent at one time and at the next moment vanishes as quickly as a cloud in the sky. The conditioned soul is encircled by such products, as well as products of sex desire, and therefore bhakti-yoga leads to gradual evaporation of the sex desire, which is summarized in three headings, namely profit, adoration and distinction. All conditioned souls are mad after these different forms of sex desire, and one shall see for himself how much he has been freed from such material hankerings based primarily on the sex desire. As a person feels his hunger satisfied after eating each morsel of foodstuff, he must similarly be able to see the degree to which he has been freed from sex desire. The sex desire is diminished along with its various forms by the process of bhakti-yoga because bhakti-yoga automatically, by the grace of the Lord, effectively results in knowledge and renunciation, even if the devotee is not materially very well educated. Knowledge means knowing things as they are, and if by deliberation it is found that there are things which are at all unnecessary, naturally the person who has acquired knowledge leaves aside such unwanted things. When the conditioned soul finds by culture of knowledge that material necessities are unwanted things, he becomes detached from such unwanted things. This stage of knowledge is called vairāgya, or detachment from unwanted things. We have previously discussed that the transcendentalist is required to be self-sufficient and should not beg from the rich blind persons to fulfill the bare necessities of life. Śukadeva Gosvāmī has suggested some alternatives for the bare necessities of life, namely the problem of eating, sleeping and shelter, but he has not suggested any alternative for sex satisfaction. One who has the sex desire still with him should not at all try to accept the renounced order of life. For one who has not attained to this stage, there is no question of a renounced order of life. So by the gradual process of devotional service under the guidance of a proper spiritual master, and following the principles of the Bhāgavatam, one must be able at least to control the gross sex desire before one accepts the renounced order of life factually.

So purification means getting free gradually from sex desire, and this is attained by meditation on the person of the Lord as described herein, beginning from the feet. One should not try to go upwards artificially without seeing for himself how much he has been released from the sex desire. The smiling face of the Lord is the Tenth Canto of Śrīmad-Bhāgavatam, and there are many upstarts who at once try to begin with the Tenth Canto and especially with the five chapters which delineate the rāsa-līlā of the Lord. This is certainly improper. By such improper study or hearing of Bhāgavatam, the material opportunists have played havoc by indulgence in sex life in the name of Bhāgavatam. This vilification of Bhāgavatam is rendered by the acts of the so-called devotees; one should be free from all kinds of sex desire before he tries to make a show of recital of Bhāgavatam. Śrī Viśvanātha Cakravartī Ṭhākura clearly defines the import of purification as cessation from sex indulgence. He says, yathā yathā dhīś ca śudhyati viṣaya-lāmpaṭyaṁ tyajati, tathā tathā dhārayed iti citta-śuddhi-tāratamyenaiva dhyāna-tāratamyam uktam. And as one gets free from the intoxication of sex indulgence by purification of intelligence, one should step forward for the next meditation, or in other words, the progress of meditation on the different limbs of the transcendental body of the Lord should be enhanced in proportion to the progress of purification of the heart. The conclusion is that those who are still entrapped by sex indulgence should never progress to meditation above the feet of the Lord; therefore recital of Śrīmad-Bhāgavatam by them should be restricted to the First and Second Cantos of the great literature. One must complete the purificatory process by assimilating the contents of the first nine cantos. Then one should be admitted into the realm of the Tenth Canto of Śrīmad-Bhāgavatam.
