Without serving Kṛṣṇa according to the vidhi-mārga regulative principles of the pāñcarātrika-vidhi, unscrupulous persons want to jump immediately to the rāga-mārga principles. Such persons are called sahajiyā. There are also demons who enjoy depicting Kṛṣṇa and His pastimes with the gopīs, taking advantage of Kṛṣṇa by their licentious character. These demons who print books and write lyrics on the rāga-mārga principles are surely on the way to hell. Unfortunately, they lead others down with them. Devotees in Kṛṣṇa consciousness should be very careful to avoid such demons. One should strictly follow the vidhi-mārga regulative principles in the worship of Lakṣmī-Nārāyaṇa, although the Lord is present in the temple as Rādhā-Kṛṣṇa. Rādhā-Kṛṣṇa includes Lakṣmī-Nārāyaṇa; therefore when one worships the Lord according to the regulative principles, the Lord accepts the service in the role of Lakṣmī-Nārāyaṇa. In The Nectar of Devotion full instructions are given about the vidhi-mārga worship of Rādhā-Kṛṣṇa, or Lakṣmī-Nārāyaṇa. Although there are sixty-four kinds of offenses one can commit in vidhi-mārga worship, in rāga-mārga worship there is no consideration of such offenses because the devotees on that platform are very much elevated, and there is no question of offense. But if we do not follow the regulative principles on the vidhi-mārga platform and keep our eyes trained to spot offenses, we will not make progress.
(Srimad Bhagavatam------4:24:45-46------purport).

A class of so-called devotees known as sahajiyās try to imitate the Lord's pastimes, although they have no understanding of the amorous love in His expansions of pleasure potency. Their superficial imitation can create havoc on the path for the advancement of one's spiritual relationship with the Lord. Material sexual indulgence can never be equated with spiritual love, which is in unadulterated goodness. The activities of the sahajiyās simply lower one deeper into the material contamination of the senses and mind. Kṛṣṇa's transcendental pastimes display eternal servitorship to Adhokṣaja, the Supreme Lord, who is beyond all conception through material senses. Materialistic conditioned souls do not understand the transcendental exchanges of love, but they like to indulge in sense gratification in the name of devotional service. The activities of the Supreme Lord can never be understood by irresponsible persons who think the pastimes of Rādhā and Kṛṣṇa to be ordinary affairs. The rāsa dance is arranged by Kṛṣṇa's internal potency yogamāyā, and it is beyond the grasp of the materially affected person. Trying to throw mud into transcendence with their perversity, the sahajiyās misinterpret the sayings tat-paratvena nirmalam (CC.2:19:170) and tat-paro bhavet. By misinterpreting tādṛśīḥ krīḍāḥ, they want to indulge in sex while pretending to imitate Lord Kṛṣṇa. But one must actually understand the imports of the words through the intelligence of the authorized gosvāmīs.
(Sri Caitanya Caritamrta------1:4:34------purport).

There is a type of neophyte devotee who is very anxious to hear about the pastimes of the Lord, especially the rāsa-līlā chapters in Śrīmad-Bhāgavatam. Such a devotee should know by this instruction that the pastimes of Pṛthu Mahārāja are nondifferent from the pastimes of the Supreme Personality of Godhead. An ideal king, Pṛthu Mahārāja exhibited all talents in showing how to rule the citizens, how to educate them, how to develop the state economically, how to fight enemies, how to perform great sacrifices (yajñas), etc. Thus it is recommended for the sahajiyā, or the neophyte devotee, to hear, chant and get others to hear about the activities of Pṛthu Mahārāja, even though one may think himself to be in the transcendental position of advanced devotional service.
(Srimad Bhagavatam------4:23:37------purport).

Taking advantage of these verses, there are some sahajiyās who, taking everything very cheaply, consider themselves elevated Vaiṣṇavas but do not care even to touch the Vedānta-sūtra or Vedānta philosophy. A real Vaiṣṇava should, however, study Vedānta philosophy, but if after studying Vedānta one does not adopt the chanting of the holy name of the Lord, he is no better than a Māyāvādī. Therefore, one should not be a Māyāvādī, yet one should not be unaware of the subject matter of Vedānta philosophy. Indeed, Caitanya Mahāprabhu exhibited His knowledge of Vedānta in His discourses with Prakāśānanda Sarasvatī. Thus it is to be understood that a Vaiṣṇava should be completely conversant with Vedānta philosophy, yet he should not think that studying Vedānta is all in all and therefore be unattached to the chanting of the holy name. A devotee must know the importance of simultaneously understanding Vedānta philosophy and chanting the holy names. If by studying Vedānta one becomes an impersonalist, he has not been able to understand Vedānta. This is confirmed in the Bhagavad-gītā (15.15). Vedānta means "the end of knowledge." The ultimate end of knowledge is knowledge of Kṛṣṇa, who is identical with His holy name. Cheap Vaiṣṇavas (sahajiyās) do not care to study the Vedānta philosophy as commented upon by the four ācāryas. In the Gauḍīya-sampradāya there is a Vedānta commentary called the Govinda-bhāṣya, but the sahajiyāsconsider such commentaries to be untouchable philosophical speculation, and they consider the ācāryas to be mixed devotees. Thus they clear their way to hell.
(Sri Caitanya Caritamrta------1:7:72------purport).

Śrīla Viśvanātha Cakravartī Ṭhākura has very critically discussed all these bhāva displays in connection with some unscrupulous neophyte's imitating the above symptoms for cheap appreciation. Not only Viśvanātha Cakravartī but also Śrīla Rūpa Gosvāmī treated them very critically. Sometimes all the above eight symptoms of ecstasy are imitated by the mundane devotees (prākṛta-sahajiyās), but the pseudo symptoms are at once detected when one sees the pseudodevotee addicted to so many forbidden things. Even though decorated with the signs of a devotee, a person addicted to smoking, drinking or illegitimate sex with women cannot have all the above-mentioned ecstatic symptoms. But it is seen that sometimes these symptoms are willfully imitated, and for this reason Śrīla Viśvanātha Cakravartī accuses the imitators of being stonehearted men. They are sometimes even affected by the reflection of such transcendental symptoms, yet if they still do not give up the forbidden habits, then they are hopeless cases for transcendental realization.
(Srimad Bhagavatam------2:3:24------purport).

The Vaiṣṇavas are by far the greatest philosophers in the world, and the greatest among them was Śrīla Jīva Gosvāmī Prabhu, whose philosophy was again presented less than four hundred years later by Śrīla Bhaktisiddhānta Sarasvatī Ṭhākura Mahārāja. Therefore one must know very well that Vaiṣṇava philosophers are not sentimentalists or cheap devotees like the sahajiyās. All the Vaiṣṇava ācāryas were vastly learned scholars who understood Vedānta philosophy fully, for unless one knows Vedānta philosophy he cannot be an ācārya. To be accepted as an ācārya among Indian transcendentalists who follow the Vedic principles, one must become a vastly learned scholar in Vedānta philosophy, either by studying it or hearing it.
(Sri Caitanya Caritamrta------1:7:102------purport).

When the world becomes degraded, civilization becomes demoniac, and for the common man the rectum and the genital are taken very seriously as the centers of all activity. Even in such a sacred place as Vṛndāvana, India, unintelligent men pass off this rectal and genital business as spiritual activity. Such people are called sahajiyā. According to their philosophy, through sexual indulgence one can elevate oneself to the spiritual platform. From these verses of Śrīmad-Bhāgavatam, however, we understand that the desires for sexual satisfaction are meant for the arvāk, the lowest among men. To rectify these rascals and fools is very difficult. After all, the sex desires of the common man are condemned in these verses. The word durmada means "wrongly directed," and nirṛti means "sinful activity." Although this clearly indicates that sex indulgence is abominable and misdirected even from the ordinary point of view, the sahajiyās nonetheless pass themselves off as devotees conducting spiritual activities. For this reason, Vṛndāvana is no longer visited by intelligent men. Sometimes we are often asked why we have made our center in Vṛndāvana. From the external point of view, it can be concluded that Vṛndāvana has become degenerate due to these sahajiyā activities, yet from the spiritual point of view, Vṛndāvana is the only place where all these sinful persons can be rectified by means of taking birth in the forms of dogs, hogs and monkeys. By living in Vṛndāvana as a dog, hog or monkey, the living entity can be elevated to the spiritual platform in the next life.
(Srimad Bhagavatam------4:29:14------purport).

The Pañca-tattva is a very important factor in understanding Śrī Caitanya Mahāprabhu. There are sahajiyās who, not knowing the importance of the Pañca-tattva, concoct their own slogans, such as bhaja nitāi gaura, rādhe śyāma, japa hare kṛṣṇa hare rāma or śrī-kṛṣṇa-caitanya prabhu-nityānanda hare kṛṣṇa hare rāma śrī-rādhe govinda. Such chants may be good poetry, but they cannot help us to go forward in devotional service. In such chants there are also many discrepancies, which need not be discussed here. Strictly speaking, when chanting the names of the Pañca-tattva, one should fully offer his obeisances: śrī-kṛṣṇa-caitanya prabhu-nityānanda śrī-advaita gadādhara śrīvāsādi-gaura-bhakta-vṛnda. By such chanting one is blessed with the competency to chant the Hare Kṛṣṇa mahā-mantra without offense. When chanting the Hare Kṛṣṇa mahā-mantra, one should also chant it fully: Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare/ Hare Rāma, Hare Rāma, Rāma Rāma, Hare Hare. One should not foolishly adopt any of the slogans concocted by imaginative devotees. If one actually wants to derive the effects of chanting, one must strictly follow the great ācāryas. This is confirmed in the Mahābhārata: mahā-jano yena gataḥ sa panthāḥ. "The real path of progress is that which is traversed by great ācāryas and authorities."
(Sri Caitanya Caritamrta------1:7:168------purport).

Unless one is associated with devotees, he cannot cultivate Kṛṣṇa consciousness. Nirjana-bhajana—cultivating Kṛṣṇa consciousness in a solitary place—is not possible for the neophyte, for he will be disturbed by the bodily necessities (eating, sleeping, mating and defending). Being so disturbed, one cannot cultivate Kṛṣṇa consciousness. We therefore see that devotees known as sahajiyā, who make everything very easy, do not associate with advanced devotees. Such persons, in the name of devotional activities, are addicted to all kinds of sinful acts—illicit sex, intoxication, gambling and meat-eating. There are many so-called devotees passing themselves off as devotees while engaging in these sinful activities. In other words, one who is influenced by sinful activity cannot be accepted as a person in Kṛṣṇa consciousness. A person addicted to sinful life cannot develop Kṛṣṇa consciousness, as indicated in this verse.
(Srimad Bhagavatam------4:29:41------purport).

This proves that bona fide devotional service is based on the conclusions of the Vedic literature. It is not based on the type of sentiment exhibited by the prākṛta-sahajiyās. The prākṛta-sahajiyās do not consult the Vedic literatures, and they are debauchees, woman-hunters and smokers of gañjā. Sometimes they give a theatrical performance and cry for the Lord with tears in their eyes. Of course, all scriptural conclusions are washed off by these tears. The prākṛta-sahajiyās do not realize that they are violating the orders of Śrī Caitanya Mahāprabhu, who specifically said that to understand Vṛndāvana and the pastimes of Vṛndāvana one must have sufficient knowledge of the śāstras (Vedic literatures). As stated in Śrīmad-Bhāgavatam (1.2.12), bhaktyā śruta-gṛhītayā. This means that devotional service is acquired from Vedic knowledge. Tac chraddadhānāḥ munayaḥ. Devotees who are actually serious attain bhakti, scientific devotional service, by hearing Vedic literatures (bhaktyā śruta-gṛhītayā). It is not that one should create something out of sentimentality, become asahajiyā and advocate such concocted devotional service. However, Śrīla Bhaktisiddhānta Sarasvatī Ṭhākura considered such sahajiyās to be more favorable than the impersonalists, who are hopelessly atheistic. The impersonalists have no idea of the Supreme Personality of Godhead. The position of the sahajiyās is far better than that of the Māyāvādī sannyāsīs. Although the sahajiyās do not think much of Vedic knowledge, they nonetheless have accepted Lord Kṛṣṇa as the Supreme Lord. Unfortunately, they mislead others from authentic devotional service.
(Sri Caitanya Caritamrta------2:1:34------purport).

Devotional service with attachment is natural, and one who has been attracted by it does not argue with those who oppose him, even though others may argue by presenting scriptural injunctions. The natural inclination to devotional service is also based on scriptural injunction, and one who has attachment for such devotional service is not required to give it up simply on the strength of scriptural argument. In this connection it should be noted that a class of so-called devotees (known as prākṛta-sahajiyā) follow their own concocted ideas and, representing themselves as Kṛṣṇa and Rādhā, indulge in debauchery. Such devotional service and attachment are false, and those so engaged are actually gliding down a hellish path. This is not the standard of rāgātmikā, or devotion. The prākṛta-sahajiyā community is actually cheated and very unfortunate.
(Teachings of Lord Caitanya).

Śrīla Bhaktisiddhānta Sarasvatī Ṭhākura comments that persons who are actually very poor because they possess not even a drop of love of Godhead or pure devotional service falsely advertise themselves as great devotees, although they cannot at any time relish the transcendental bliss of devotional service. A class of so-called devotees known as prākṛta-sahajiyās sometimes display devotional symptoms to exhibit their good fortune. They are pretending, however, because these devotional features are only external. The prākṛta-sahajiyās exhibit these symptoms to advertise their so-called advancement in love of Kṛṣṇa, but instead of praising the prākṛta-sahajiyās for their symptoms of transcendental ecstasy, pure devotees do not like to associate with them. It is not advisable to equate the prākṛta-sahajiyās with pure devotees. When one is actually advanced in ecstatic love of Kṛṣṇa, he does not try to advertise himself. Instead, he endeavors more and more to render service to the Lord.
(Sri Caitanya Caritamrta------3:20:28------purport).

The scripture known as Brahma-yāmala states as follows: "If someone wants to pose himself as a great devotee without following the authorities of the revealed scriptures, then his activities will never help him to make progress in devotional service. Instead, he will simply create disturbances for the sincere students of devotional service." Those who do not strictly follow the principles of revealed scriptures are generally called sahajiyās—those who have imagined everything to be cheap, who have their own concocted ideas, and who do not follow the scriptural injunctions. Such persons are simply creating disturbances in the discharge of devotional service.
(Nectar of Devotion).

“A devotee on the topmost platform of devotional service always humbly thinks that he is not rendering any devotional service. He thinks that he is poor in devotional service and that his body is material. On the other hand, those known as the sahajiyās foolishly think that their material bodies are transcendental. Because of this, they are always bereft of the association of pure devotees, and thus they cannot behave like Vaiṣṇavas. Observing the defects of the sahajiyās, Śrīla Bhaktivinoda Ṭhākura has sung as follows in his book Kalyāṇa-kalpataru:
āmi ta' vaiṣṇava, e-buddhi ha-ile,
amānī nā haba āmi
pratiṣṭhāśā āsi’, hṛdaya dūṣibe,
ha-iba niraya-gāmī
nije śreṣṭha jāni’, ucchiṣṭādi-dāne,
habe abhimāna bhāra
tāi śiṣya tava, thākiyā sarvadā,
nā la-iba pūjā kāra
“"If I think I am a Vaiṣṇava, I shall look forward to receiving respect from others. And if the desire for fame and reputation pollutes my heart, certainly I shall go to hell. By giving others the remnants of my food, I shall consider myself superior and shall be burdened with the weight of false pride. Therefore, always remaining your surrendered disciple, I shall not accept worship from anyone else."
(Sri Caitanya Caritamrta------3:4:173------purport).

We can see from practical experience that there are different types of Vaiṣṇavas. The prākṛta-sahajiyās generally chant the Hare Kṛṣṇa mahā-mantra, yet they are attached to women, money and intoxication. Although such persons may chant the holy name of the Lord, they are not yet properly purified. Such people should be respected within one's mind, but their association should be avoided. Those who are innocent but simply carried away by bad association should be shown favor if they are eager to receive proper instructions from pure devotees, but those neophyte devotees who are actually initiated by the bona fide spiritual master and are seriously engaged in carrying out the orders of the spiritual master should be offered respectful obeisances.
