Purport: 

All the inhabitants of Vṛndāvana are Vaiṣṇavas. They are all-auspicious because somehow or other they always chant the holy name of Kṛṣṇa. Even though some of them do not strictly follow the rules and regulations of devotional service, on the whole they are devotees of Kṛṣṇa and chant His name directly or indirectly. Purposely or without purpose, even when they pass on the street they are fortunate enough to exchange greetings by saying the name of Rādhā or Kṛṣṇa. Thus directly or indirectly they are auspicious.

The present city of Vṛndāvana has been established by the Gauḍīya Vaiṣṇavas since the six Gosvāmīs went there and directed the construction of their different temples. Of all the temples in Vṛndāvana, ninety percent belong to the Gauḍīya Vaiṣṇava sect, the followers of the teachings of Lord Caitanya Mahāprabhu and Nityānanda, and seven temples are very famous. The inhabitants of Vṛndāvana do not know anything but the worship of Rādhā and Kṛṣṇa. In recent years some unscrupulous so-called priests known as caste gosvāmīs have introduced the worship of demigods privately, but no genuine and rigid Vaiṣṇavas participate in this. Those who are serious about the Vaiṣṇava method of devotional activities do not take part in such worship of demigods.

The Gauḍīya Vaiṣṇavas never differentiate between Rādhā-Kṛṣṇa and Lord Caitanya. They say that since Lord Caitanya is the combined form of Rādhā-Kṛṣṇa, He is not different from Rādhā and Kṛṣṇa. But some misled people try to prove that they are greatly elevated by saying that they like to chant the holy name of Lord Gaura instead of the names of Rādhā and Kṛṣṇa. Thus they purposely differentiate between Lord Caitanya and Rādhā-Kṛṣṇa. According to them, the system of nadīyā-nāgarī, which they have recently invented in their fertile brains, is the worship of Gaura, Lord Caitanya, but they do not like to worship Rādhā and Kṛṣṇa. They put forward the argument that since Lord Caitanya Himself appeared as Rādhā and Kṛṣṇa combined, there is no necessity of worshiping Rādhā and Kṛṣṇa. Such differentiation by so-called devotees of Lord Caitanya Mahāprabhu is considered disruptive by pure devotees. Anyone who differentiates between Rādhā-Kṛṣṇa and Gaurāṅga is to be considered a plaything in the hands of māyā.

There are others who are against the worship of Caitanya Mahāprabhu, thinking Him mundane. But any sect that differentiates between Lord Caitanya Mahāprabhu and Rādhā-Kṛṣṇa, either by worshiping Rādhā-Kṛṣṇa as distinct from Lord Caitanya or by worshiping Lord Caitanya but not Rādhā-Kṛṣṇa, is in the group of prākṛta-sahajiyās.

Śrīla Kṛṣṇadāsa Kavirāja Gosvāmī, the author of Śrī Caitanya-caritāmṛta, predicts in verses 225 and 226 that in the future those who manufacture imaginary methods of worship will gradually give up the worship of Rādhā-Kṛṣṇa, and although they will call themselves devotees of Lord Caitanya, they will also give up the worship of Caitanya Mahāprabhu and fall down into material activities. For the real worshipers of Lord Caitanya, the ultimate goal of life is to worship Śrī Śrī Rādhā and Kṛṣṇa.
