If one is seriously interested in Kṛṣṇa conscious activities, he must be ready to follow the rules and regulations laid down by the ācāryas, and he must understand their conclusions. The śāstra says, dharmasya tattvaṁ nihitaṁ guhāyāṁ mahā-jano yena gataḥ sa panthāḥ (Mahābhārata, Vana-parva 313.117). It is very difficult to understand the secret of Kṛṣṇa consciousness, but one who advances by the instruction of the previous ācāryas and follows in the footsteps of his predecessors in the line of disciplic succession will have success. Others will not. Śrīla Narottama dāsa Ṭhākura says in this connection, chāḍiyā vaiṣṇava-sevā nistāra peyeche kebā: “Unless one serves the spiritual master and ācāryas, one cannot be liberated.” Elsewhere he says:
ei chaya gosāñi yāṅra—mui tāṅra dāsa
tāṅ-sabāra pada-reṇu mora pañca-grāsa
“I simply accept a person who follows in the footsteps of the six Gosvāmīs, and the dust of such a person’s lotus feet is my food.”
(Sri Caitanya Caritamrta-----1:8:7-----purport).

In a song by Narottama dāsa Ṭhākura it is stated:
rūpa-raghunātha-pade ha-ibe ākuti
kabe hāma bujhaba se yugala-pīriti
The conjugal love between Rādhā and Kṛṣṇa, which is called yugala-pīriti, is not understandable by mundane scholars, artists or poets. It is simply to be understood by devotees who strictly follow in the footsteps of the six Gosvāmīs. Sometimes so-called artists and poets try to understand the love affairs of Rādhā and Kṛṣṇa, and they publish cheap books of poetry and pictures on the subject. Unfortunately, however, they do not understand the transcendental affairs of Rādhā and Kṛṣṇa even to the smallest degree. They are simply meddling in a matter in which they are not fit even to enter.
(Sri Caitanya Caritamrta-----1:17:304-----purport).

Sanātana Gosvāmī was enjoined (1) to broadcast the revealed scriptures on devotional service and establish the conclusions of devotional service, (2) to reestablish lost places of pilgrimage like Vṛndāvana and Rādhā-kuṇḍa, (3) to establish the Vṛndāvana method of temple worship and install Deities in temples (Śrī Sanātana Gosvāmī established the Madana-mohana temple, and Rūpa Gosvāmī established the Govindajī temple), and (4) to enunciate the behavior of a Vaiṣṇava (as Śrīla Sanātana Gosvāmī did in the Hari-bhakti-vilāsa). In this way Sanātana Gosvāmī was empowered to establish the cult of Vaiṣṇavism. As stated by Śrīnivāsa Ācārya in his Ṣaḍ-gosvāmy-aṣṭaka (2):
nānā-śāstra-vicāraṇaika-nipuṇau sad-dharma-saṁsthāpakau
lokānāṁ hita-kāriṇau tri-bhuvane mānyau śaraṇyākarau
rādhā-kṛṣṇa-padāravinda-bhajanānandena mattālikau
vande rūpa-sanātanau raghu-yugau śrī-jīva-gopālakau
"I offer my respectful obeisances unto the Six Gosvāmīs, namely Śrī Sanātana Gosvāmī, Śrī Rūpa Gosvāmī, Śrī Raghunātha Bhaṭṭa Gosvāmī, Śrī Raghunātha dāsa Gosvāmī, Śrī Jīva Gosvāmī and Śrī Gopāla Bhaṭṭa Gosvāmī, who are very expert in scrutinizingly studying all the revealed scriptures with the aim of establishing eternal religious principles for the benefit of all human beings. Thus they are honored all over the three worlds, and they are worth taking shelter of because they are absorbed in the mood of the gopīs and are engaged in the transcendental loving service of Rādhā and Kṛṣṇa."
This Kṛṣṇa consciousness movement continues the tradition of the Six Gosvāmīs, especially Śrīla Sanātana Gosvāmī and Śrīla Rūpa Gosvāmī. Serious students of this Kṛṣṇa consciousness movement must understand their great responsibility to preach the cult of Vṛndāvana (devotional service to the Lord) all over the world. We now have a nice temple in Vṛndāvana, and serious students should take advantage of it. I am very hopeful that some of our students can take up this responsibility and render the best service to humanity by educating people in Kṛṣṇa consciousness.
(Sri Caitanya Caritamrta-----2:23:104-----purport).

Śrīla Bhaktisiddhānta Sarasvatī Ṭhākura says that a devotee is attracted by the service of the inhabitants of Vṛndāvana—namely the cowherd men, Mahārāja Nanda, mother Yaśodā, Rādhārāṇī, the gopīs and the cows and calves. An advanced devotee is attracted by the service rendered by an eternal servitor of the Lord. This attraction is called spontaneous attraction. Technically it is called svarūpa-upalabdhi. This stage is not achieved in the beginning. In the beginning one has to render service strictly according to the regulative principles set forth by the revealed scriptures and the spiritual master. By continuously rendering service through the process of vaidhī bhakti, one's natural inclination is gradually awakened. That is called spontaneous attraction, or rāgānugā bhakti.
An advanced devotee situated on the platform of spontaneity is already very expert in śāstric instruction, logic and argument. When he comes to the point of eternal love for Kṛṣṇa, no one can deviate him from that position, neither by argument nor by śāstric evidence. An advanced devotee has realized his eternal relationship with the Lord, and consequently he does not accept the logic and arguments of others. Such an advanced devotee has nothing to do with the sahajiyās, who manufacture their own way and commit sins by indulging in illicit sex, intoxication and gambling, if not meat-eating. Sometimes the sahajiyās imitate advanced devotees and live in their own whimsical way, avoiding the principles set down in the revealed scriptures. Unless one follows the Six Gosvāmīs—Śrī Rūpa, Sanātana, Raghunātha Bhaṭṭa, Śrī Jīva, Gopāla Bhaṭṭa and Raghunātha dāsa-one cannot be a bona fide spontaneous lover of Kṛṣṇa. In this connection, Śrīla Narottama dāsa Ṭhākura says, rūpa-raghunātha-pade haibe ākuti kabe hāma bujhaba se yugala pirīti. The sahajiyās' understanding of the love affairs between Rādhā and Kṛṣṇa is not bona fide because they do not follow the principles laid down by the Six Gosvāmīs. Their illicit connection and their imitation of the dress of Rūpa Gosvāmī, as well as their avoidance of the prescribed methods of revealed scriptures, will lead them to the lowest regions of hell. These imitative sahajiyās are cheated and unfortunate. They are not equal to advanced devotees (paramahaṁsas). Debauchees and paramahaṁsas are not on the same level.
(Sri Caitanya Caritamrta-----2:22:153-----purport).

O demigods, one who has no compassion for humanity in its suffering and does not sacrifice his impermanent body for the higher causes of religious principles or eternal glory is certainly pitied even by the immovable beings."
In this regard, a very exalted example was set by Lord Śrī Caitanya Mahāprabhu and the six Gosvāmīs of Vṛndāvana. Concerning Śrī Caitanya Mahāprabhu it is said in Śrīmad-Bhāgavatam (11.5.34):
tyaktvā sudustyaja-surepsita-rājya-lakṣmīṁ
dharmiṣṭha ārya-vacasā yad agād araṇyam
māyā-mṛgaṁ dayitayepsitam anvadhāvad
vande mahā-puruṣa te caraṇāravindam
"We offer our respectful obeisances unto the lotus feet of the Lord, upon whom one should always meditate. He left His householder life, leaving aside His eternal consort, whom even the denizens of heaven adore. He went into the forest to deliver the fallen souls, who are put into illusion by material energy." To accept sannyāsa means to commit civil suicide, but sannyāsa is compulsory, at least for every brāhmaṇa, every first-class human being. Śrī Caitanya Mahāprabhu had a very young and beautiful wife and a very affectionate mother. Indeed, the affectionate dealings of His family members were so pleasing that even the demigods could not expect such happiness at home. Nevertheless, for the deliverance of all the fallen souls of the world, Śrī Caitanya Mahāprabhu took sannyāsa and left home when He was only twenty-four years old. He lived a very strict life as a sannyāsī, refusing all bodily comforts. Similarly, His disciples the six Gosvāmīs were ministers who held exalted positions in society, but they also left everything to join the movement of Śrī Caitanya Mahāprabhu. Śrīnivāsa Ācārya says:
tyaktvā tūrṇam aśeṣa-maṇḍala-pati-śreṇīṁ sadā tucchavat
bhūtvā dīna-gaṇeśakau karuṇayā kaupīna-kanthāśritau
These Gosvāmīs left their very comfortable lives as ministers. Zamindars and learned scholars and joined Śrī Caitanya Mahāprabhu's movement, just to show mercy to the fallen souls of the world (dīna-gaṇeśakau karuṇayā). Accepting very humble lives as mendicants, wearing no more than loincloths and torn quilts (kaupīna-kantha). they lived in Vṛndāvana and followed Śrī Caitanya Mahāprabhu's order to excavate Vṛndāvana's lost glories.
Similarly. everyone else with a materially comfortable condition in this world should join the Kṛṣṇa consciousness movement to elevate the fallen souls. The words bhūta-dayayā, māyā-mṛgaṁ dayitayepsitam and dīna-gaṇeśakau karuṇayā all convey the same sense. These are very significant words for those interested in elevating human society to a proper understanding of life. One should join the Kṛṣṇa consciousness movement, following the examples of such great personalities as Śrī Caitanya Mahāprabhu, the six Gosvāmīs and, before them, the great sage Dadhīci. Instead of wasting one's life for temporary bodily comforts. one should always be prepared to give up one's life for better causes. After all, the body will be destroyed. Therefore one should sacrifice it for the glory of distributing religious principles throughout the world.
