Holy places like Vṛndāvana, Hardwar, Prayāga and Jagannātha Purī are especially meant for the execution of devotional service. Vṛndāvana specifically is the most exalted and preferred holy place for Vaiṣṇava devotees of Lord Kṛṣṇa who are aspiring to return back to Godhead, the Vaikuṇṭha planets. There are many devotees in Vṛndāvana who regularly bathe in the Yamunā, and this cleanses all the contamination of the material world. By constantly chanting and hearing the holy names and pastimes of the Supreme Lord, one certainly becomes purified and becomes a fit candidate for liberation. However, if one purposefully falls victim to sense gratification, he has to be punished, at least for one lifetime, like Bharata Mahārāja.
(Srimad Bhagavatam------5:8:31------purport).

To perform devotional service means to follow in the footsteps of Rādhārāṇī, and devotees in Vṛndāvana put themselves under the care of Rādhārāṇī in order to achieve perfection in their devotional service. In other words, devotional service is not an activity of the material world; it is directly under the control of Rādhārāṇī. In Bhagavad-gītā it is confirmed that the mahātmās, or great souls, are under the protection of daivī prakṛti, the internal energy—Rādhārāṇī. So, being directly under the control of the internal potency of Kṛṣṇa, devotional service attracts even Kṛṣṇa Himself.
(Nectar of Devotion).

In fact, Rādhārāṇī is the internal potency of Śrī Kṛṣṇa, and She eternally intensifies the pleasure of Śrī Kṛṣṇa. Impersonalists cannot understand this without the help of a mahā-bhāgavata devotee. The very name "Rādhā" suggests that Śrīmatī Rādhārāṇī is eternally the topmost mistress of the comforts of Śrī Kṛṣṇa. As such, She is the medium transmitting the living entities' service to Śrī Kṛṣṇa. Devotees in Vṛndāvana therefore seek the mercy of Śrīmatī Rādhārāṇī in order to be recognized as loving servitors of Śrī Kṛṣṇa.
(Sri Caitanya Caritamrta------1:4:56-------purport).

We must always remember, however, that such eagerness to follow in the footsteps of the denizens of Vraja (Vṛndāvana) is not possible unless one is freed from material contamination. In following the regulative principles of devotional service, there is a stage called anartha-nivṛtti, which means the disappearance of all material contamination. Sometimes someone is found imitating such devotional love, but factually he is not freed from anarthas, or unwanted habits. It has been seen that a so-called devotee proclaims himself a follower of Nanda, Yaśodā or the gopīs, while at the same time his abominable attraction for mundane sex life is visible. Such a manifestation of divine love is mere imitation and has no value. When one is actually spontaneously attracted to the loving principles of the gopīs, there will be found no trace of any mundane contamination in his character.
Therefore, in the beginning, everyone should strictly follow the regulative principles of devotional service, according to the injunctions of the scriptures and the spiritual master. Only after the stage of liberation from material contamination can one actually aspire to follow in the footsteps of the devotees in Vṛndāvana.
(Nectar of Devotion).

Impersonal realization of the Absolute Truth is certainly transcendental, but this does not mean that one who has attained this realization can understand the sac-cid-ānanda form of the Lord. Similarly, Paramātmā realization—realization of the plenary expansion of the Absolute Truth within everyone's heart—is also an incomplete understanding of the Absolute Truth. Even a devotee of the Personality of Godhead Nārāyaṇa cannot actually understand the transcendental attractive features of Kṛṣṇa. Indeed, a devotee of Kṛṣṇa who is attached to the sublime attractive features of the Lord does not consider Nārāyaṇa very important. When the gopīs sometimes saw Kṛṣṇa in the form of Nārāyaṇa, they were not very much attracted to Him. The gopīs never addressed Kṛṣṇa as Rukmiṇī-ramaṇa. Kṛṣṇa's devotees in Vṛndāvana address Him as Rādhāramaṇa, Nandanandana and Yaśodānandana, but not as Vasudeva-nandana or Devakī-nandana. Although according to the material conception Nārāyaṇa, Rukmiṇī-ramaṇa and Kṛṣṇa are one and the same, in the spiritual world one cannot use the name Rukmiṇī-ramaṇa or Nārāyaṇa in place of the name Kṛṣṇa. If one does so out of a poor fund of knowledge, his mellow with the Lord becomes spiritually faulty and is called rasābhāsa, an overlapping of transcendental mellows. The advanced devotee who has actually realized the transcendental features of the Lord will not commit the mistake of creating a rasābhāsa situation by using one name for another. Because of the influence of Kali-yuga, there is much rasābhāsa in the name of extravagance and liberal-mindedness. Such fanaticism is not very much appreciated by pure devotees.
(Sri Caitanya Caritamrta------2:8:90-------purport).

Although it is very difficult to enter into the Rādhā-Kṛṣṇa pastimes, most of the devotees of Vṛndāvana are attracted to the rādhā-kṛṣṇa-līlā. However, since Nitāi-Gauracandra are direct incarnations of Balarāma and Kṛṣṇa, we can be directly in touch with Lord Balarāma and Lord Kṛṣṇa through Śrī Caitanya Mahāprabhu and Nityānanda Prabhu. Those who are highly elevated in Kṛṣṇa consciousness can enter into the pastimes of Rādhā-Kṛṣṇa through the mercy of Śrī Caitanya Mahāprabhu. It is said, śrī-kṛṣṇa-caitanya rādhā-kṛṣṇa nahe anya: "Śrī Kṛṣṇa Caitanya Mahāprabhu is a combination of Rādhā and Kṛṣṇa."
(Sri Caitanya Caritamrta------2:16:281-------purport).

It is said by Śrī Rūpa Gosvāmī, "When one is actually liberated from material contamination, he can always remember an eternal devotee in Vṛndāvana in order to love Kṛṣṇa in the same capacity. And developing such an aptitude, one will always live in Vṛndāvana, even within his mind." The purport is that if it is possible one should go and physically be present at Vrajabhūmi, Vṛndāvana, and be engaged always in the service of the Lord, following the devotees in Vraja-dhāma, the spiritual realm of Vraja. If it is not possible, however, to be physically present at Vṛndāvana, one can meditate anywhere upon living in that situation. Wherever he may be, one must always think about life in Vraja-dhāma and about following in the footsteps of a particular devotee in the service of the Lord.
(Nectar of Devotion).

“The original inhabitants of Vṛndāvana are attached to Kṛṣṇa spontaneously in devotional service. Nothing can compare to such spontaneous devotional service, which is called rāgātmikā bhakti. When a devotee follows in the footsteps of the devotees of Vṛndāvana, his devotional service is called rāgānugā bhakti.
In his Bhakti-sandarbha, Jīva Gosvāmī states:

tad evaṁ tat-tad-abhimāna-lakṣaṇa-bhāva-viśeṣeṇa svābhāvika-rāgasya vaiśiṣṭye sati tat-tad-rāga-prayuktā śravaṇa-kīrtana-smaraṇa-pāda-sevana-vandanātma-nivedana-prāyā bhaktis teṣāṁ rāgātmikā bhaktir ity ucyate. . . . tatas tadīyaṁ rāgaṁ rucyānugacchantī sā rāgānugā.

When a pure devotee follows the footsteps of a devotee in Vṛndāvana, he develops rāgānugā bhakti.
(Sri Caitanya Caritamrta------2:22:149-------translation and purport).

“"When an advanced, realized devotee hears about the affairs of the devotees of Vṛndāvana—in the mellows of śānta, dāsya, sakhya, vātsalya and mādhurya—he becomes inclined in one of these ways, and his intelligence becomes attracted. Indeed, he begins to covet that particular type of devotion. When such covetousness is awakened, one"s intelligence no longer depends on the instructions of śāstra (revealed scripture) or on logic and argument.’
This verse is also found in the Bhakti-rasāmṛta-sindhu (1.2.292).
(Sri Caitanya Caritamrta------2:22:155-------translation and purport).

“In the seed of affection, there is attachment which goes by two names, rati and bhāva. The Supreme Personality of Godhead comes under the control of such attachment.
Śrīla Bhaktisiddhānta Sarasvatī Ṭhākura comments on this verse. Externally a devotee performs all the items of devotional service in nine different ways, beginning with śravaṇa and kīrtana, and within his mind he always thinks of his eternal relationship with Kṛṣṇa and follows in the footsteps of the devotees of Vṛndāvana. If one engages himself in the service of Rādhā and Kṛṣṇa in this way, he can transcend the regulative principles enjoined in the śāstras and, through his spiritual master, fully engage in rendering spontaneous love to Kṛṣṇa. In this way, he attains affection at the lotus feet of Kṛṣṇa. Kṛṣṇa actually comes under the control of such spontaneous feelings, and ultimately one can attain association with the Lord.
(Sri Caitanya Caritamrta------2:22:165-------translation and purport).

The author of Caitanya-caritāmṛta, Kṛṣṇadāsa Kavirāja Gosvāmī, was an inhabitant of Vṛndāvana and a great devotee. He had been living with his family in Katwa, a small town in the district of Burdwan in Bengal. His family also worshiped Rādhā-Kṛṣṇa, and once when there was some misunderstanding amongst his family about devotional service, Kṛṣṇadāsa Kavirāja was advised by Nityānanda Prabhu in a dream to leave home and go to Vṛndāvana. Although he was very old, he started out that very night and went to live in Vṛndāvana. While he was there, he met some of the Gosvāmīs, principal disciples of Lord Caitanya Mahāprabhu. He was requested to write Caitanya-caritāmṛta by the devotees of Vṛndāvana. Although he began this work at a very old age, by the grace of Lord Caitanya he finished it. Today it remains the most authoritative book on Caitanya's philosophy and life.
(Teachings of Lord Caitanya).

Lakṣmī, the goddess of fortune, has complete knowledge of Kṛṣṇa's opulences, but she could not achieve the association of Kṛṣṇa by dint of such knowledge. The devotees in Vṛndāvana, however, actually enjoy the association of Kṛṣṇa.
(Sri Caitanya Caritamrta------3:7:28---------purport).
