Śrīla Bhaktivinoda Ṭhākura considers the brahma-bhūta stage in two divisions—svarūpa-gata and vastu-gata. One who has understood Kṛṣṇa in truth but is still maintaining some material connection is known to be situated in his svarūpa, his original consciousness. When that original consciousness is completely spiritual, it is called Kṛṣṇa consciousness. One who lives in such consciousness is actually living in Vṛndāvana. He may live anywhere; material location doesn’t matter. When by the grace of Kṛṣṇa one thus advances, he becomes completely uncontaminated by the material body and mind and at that time factually lives in Vṛndāvana. That stage is called vastu-gata.
(Sri Caitanya Caritamrta--------2:8:139--------purport).

The mind's activities are thinking, feeling and willing, by which the mind accepts materially favorable things and rejects the unfavorable. This is the consciousness of people in general. But when one's mind does not accept and reject but simply becomes fixed on the lotus feet of Kṛṣṇa, then one's mind becomes as good as Vṛndāvana. Wherever Kṛṣṇa is, there also are Śrīmatī Rādhārāṇī, the gopīs, the cowherd boys and all the other inhabitants of Vṛndāvana. Thus as soon as one fixes Kṛṣṇa in his mind, his mind becomes identical with Vṛndāvana. In other words, when one's mind is completely free from all material desires and is engaged only in the service of the Supreme Personality of Godhead, then one always lives in Vṛndāvana, and nowhere else.

Śrīla Narottama dāsa Ṭhākura, Śrīnivāsa Ācārya, Śrīla Jagannātha dāsa Bābājī Mahārāja, Śrī Bhagavān dāsa Bābājī Mahārāja and Śrīla Gaurakiśora dāsa Bābājī Mahārāja, and later Śrīla Bhaktivinoda Ṭhākura of Calcutta, always engaged in nāma-bhajana and certainly did not live anywhere but Vṛndāvana. Presently, the members of the Hare Kṛṣṇa movement throughout the world live in materially opulent cities, such as London, New York, Los Angeles, Paris, Moscow, Zurich and Stockholm. However, we are satisfied with following in the footsteps of Śrīla Bhaktivinoda Ṭhākura and other ācāryas. Because we live in the temples of Rādhā-Kṛṣṇa and continuously hold hari-nāma-saṅkīrtana—the chanting of Hare Kṛṣṇa—we consequently live in Vṛndāvana and nowhere else. We are also following in the footsteps of Śrī Caitanya Mahāprabhu by attempting to construct a temple in Vṛndāvana for our disciples throughout the world to visit.

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).

Lord Rāmacandra showed His favor to His brothers by ordering Them to go out. Many of the Lord's devotees residing in Vṛndāvana have taken the vow not to leave Vṛndāvana to preach Kṛṣṇa consciousness. But the Lord says that Kṛṣṇa consciousness should be spread all over the world, in every village and every town. This is the open order of Lord Caitanya Mahāprabhu.
pṛthivīte āche yata nagarādi grāma
sarvatra pracāra haibe mora nāma
A pure devotee, therefore, must execute the order of the Lord and must not gratify his senses by remaining stagnant in one place, falsely proud, thinking that because he does not leave Vṛndāvana but chants in a solitary place he has become a great devotee. A devotee must carry out the order of the Supreme Personality of Godhead. Caitanya Mahāprabhu said, yāre dekha, tāre kaha 'kṛṣṇa'-upadeśa (CC.2:7:128). Every devotee, therefore, should spread Kṛṣṇa consciousness by preaching, asking whomever he meets to accept the order of the Supreme Personality of Godhead. The Lord says, sarva-dharmān parityajya mām ekaṁ śaraṇaṁ vraja: (B.G.18:66) "Abandon all varieties of religion and just surrender unto Me." This is the order of the Lord, who speaks as the supreme emperor. Everyone should be induced to accept this order, for this is victory (dig-vijaya). And it is the duty of the soldier, the devotee, to impress upon everyone this philosophy of life.

Of course, those who are kaniṣṭha-adhikārīs do not preach, but the Lord shows mercy to them also, as He did by staying personally in Ayodhyā to give audience to the people in general. One should not mistakenly think that the Lord asked His younger brothers to leave Ayodhyā because He especially favored the citizens. The Lord is merciful to everyone, and He knows how to show His favor to each individual person according to his capacity. One who abides by the order of the Lord is a pure devotee.
(Srimad Bhagavatam-------9:11:25-------purport).

How can a devotee be affected by his past misconduct and vicious activities? In Brahma-saṁhitā (5.54) it is said, karmāṇi nirdahati kintu ca bhakti-bhājām: "For those engaged in devotional service, bhakti-bhajana, the results of past deeds are indemnified." According to this, Bharata Mahārāja could not be punished for his past misdeeds. The conclusion must be that Mahārāja Bharata purposefully became over-addicted to the deer and neglected his spiritual advancement. To immediately rectify his mistake, for a short time he was awarded the body of a deer. This was just to increase his desire for mature devotional service. Although Bharata Mahārāja was awarded the body of an animal, he did not forget what had previously happened due to his purposeful mistake. He was very anxious to get out of his deer body, and this indicates that his affection for devotional service was intensified, so much so that he was quickly to attain perfection in a brāhmaṇa body in the next life. It is with this conviction that we declare in our Back to Godhead magazine that devotees like the gosvāmīs living in Vṛndāvanawho purposely commit some sinful activity are born in the bodies of dogs, monkeys and tortoises in that holy land. Thus they take on these lower life forms for a short while, and after they give up those animal bodies, they are again promoted to the spiritual world. Such punishment is only for a short period, and it is not due to past karma. It may appear to be due to past karma, but it is offered to rectify the devotee and bring him to pure devotional service.
(Srimad Bhagavatam-------5:8:26-------purport).

To go to the forest and live there with the animals, meditating upon the Supreme Personality of Godhead, is the only means by which to give up lusty desires. Unless one gives up such desires, one's mind cannot be freed from material contamination. Therefore, if one is at all interested in being freed from the bondage of repeated birth, death, old age and disease, after a certain age one must go to the forest. pañcāśordhvaṁ vanaṁ vrajet. After fifty years of age, one should voluntarily give up family life and go to the forest. The best forest is Vṛndāvana, where one need not live with the animals but can associate with the Supreme Personality of Godhead, who never leaves Vṛndāvana. Cultivating Kṛṣṇa consciousness in Vṛndāvana is the best means of being liberated from material bondage, for in Vṛndāvana one can automatically meditate upon Kṛṣṇa. Vṛndāvana has many temples, and in one or more of these temples one may see the form of the Supreme Lord as Rādhā-Kṛṣṇa or Kṛṣṇa-Balarāma and meditate upon this form. As expressed here by the words brahmaṇy adhyāya, one should concentrate one's mind upon the Supreme Lord, Parabrahman. This Parabrahman is Kṛṣṇa, as confirmed by Arjuna in Bhagavad-gītā (paraṁ brahma paraṁ dhāma pavitraṁ paramaṁ bhavān (B.G.10:12). Kṛṣṇa and His abode, Vṛndāvana, are not different. Śrī Caitanya Mahāprabhu said, ārādhyo bhagavān vrajeśa-tanayas tad-dhāma vṛndāvanam. Vṛndāvana is as good as Kṛṣṇa. Therefore, if one somehow or other gets the opportunity to live in Vṛndāvana, and if one is not a pretender but simply lives in Vṛndāvana and concentrates his mind upon Kṛṣṇa, one is liberated from material bondage. One's mind is not purified, however, even in Vṛndāvana, if one is agitated by lusty desires. One should not live in Vṛndāvana and commit offenses, for a life of offenses in Vṛndāvana is no better than the lives of the monkeys and hogs there. Many monkeys and hogs live in Vṛndāvana, and they are concerned with their sexual desires. Men who have gone to Vṛndāvana but who still hanker for sex should immediately leave Vṛndāvana and stop their grievous offenses at the lotus feet of the Lord. There are many misguided men who live in Vṛndāvana to satisfy their sexual desires, but they are certainly no better than the monkeys and hogs. Those who are under the control of māyā, and specifically under the control of lusty desires, are called māyā-mṛga. Indeed, everyone in the conditional stage of material life is a māyā-mṛga. It is said, māyā-mṛgaṁ dayitayepsitam anvadhāvad: (S.B.11:5:34) Śrī Caitanya Mahāprabhu took sannyāsa to show His causeless mercy to the māyā-mṛgas, the people of this material world, who suffer because of lusty desires. One should follow the principles of Śrī Caitanya Mahāprabhu and always think of Kṛṣṇa in full Kṛṣṇa consciousness. Then one will be eligible to live in Vṛndāvana, and his life will be successful.
