Śrīla Narottama dāsa Ṭhākura has sung, gṛhe vā vanete thāke, 'hā gaurāṅga' bale ḍāke: whether one is situated in the forest or at home, if he is engaged in the devotional service of Lord Caitanya, he is a liberated person. Here this is also repeated. For one who has not controlled his senses, going to the forest to become a so-called yogī is meaningless.
(Srimad Bhagavatam---5:1:17----purport).

According to expert opinion, Balarāma, as the chief of the original quadruple forms, is also the original Saṅkarṣaṇa. Balarāma, the first expansion of Kṛṣṇa, expands Himself in five forms: (1) Mahā-saṅkarṣaṇa, (2) Kāraṇodakaśāyī, (3) Garbhodakaśāyī, (4) Kṣīrodakaśāyī, and (5) Śeṣa. These five plenary portions are responsible for both the spiritual and material cosmic manifestations. In these five forms Lord Balarāma assists Lord Kṛṣṇa in His activities. The first four of these forms are responsible for the cosmic manifestations, whereas Śeṣa is responsible for personal service to the Lord. Śeṣa is called Ananta, or unlimited, because He assists the Personality of Godhead in His unlimited expansions by performing an unlimited variety of services. Śrī Balarāma is the servitor Godhead who serves Lord Kṛṣṇa in all affairs of existence and knowledge. Lord Nityānanda Prabhu, who is the same servitor Godhead, Balarāma, performs the same service to Lord Gaurāṅga by constant association.
(Sri Caitanya Caritamrta----1:5:10----purport).

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.
(Sri Caitanya Caritamrta----1:5:232----purport).

In the Vedas it is said, parāsya śaktir vividhaiva śrūyate: (Cc. Madhya 13.65, purport) "The varieties of energy of the Supreme Personality of Godhead are differently known." From this statement of the Vedas one can understand that there are eternal varieties of humors, or tastes, in the spiritual world. Śrī Gaurāṅga, Śrī Nityānanda, Śrī Advaita, Śrī Gadādhara and Śrīvāsa Ṭhākura are all on the same platform, but in spiritually distinguishing between them one should understand that Śrī Caitanya Mahāprabhu is the form of a devotee, Nityānanda Prabhu appears in the form of a devotee's spiritual master, Advaita Prabhu is the form of a bhakta (devotee) incarnation, Gadādhara Prabhu is the energy of a bhakta, and Śrīvāsa Ṭhākura is a pure devotee. Thus there are spiritual distinctions between them.
(Sri Caitanya Caritamrta----1:7:5----purport).

Śrīla Bhaktivinoda Ṭhākura explains the Gaura-gopāla mantra in his Amṛta-pravāha-bhāṣya. Worshipers of Śrī Gaurasundara accept the four syllables gau-ra-aṅ-ga as the Gaura mantra, but pure worshipers of Rādhā and Kṛṣṇa accept the four syllables rā-dhā kṛṣ-ṇa as the Gaura-gopāla mantra. However, Vaiṣṇavas consider Śrī Caitanya Mahāprabhu nondifferent from Rādhā-Kṛṣṇa (śrī-kṛṣṇa-caitanya rādhā-kṛṣṇa nahe anya). Therefore one who chants the mantra "gaurāṅga" and one who chants the names of Rādhā and Kṛṣṇa are on the same level.
(Sri Caitanya Caritamrta----3:2:31----purport).

There is a very nice song sung by Śrī Narottama Dāsa Ṭhākura, a great devotee and ācārya in the disciplic succession from Lord Caitanya. Narottama Dāsa sings: "When will there be transcendental eruptions all over my body simply by my hearing the name of Gaurāṅga? When will tears incessantly flow from my eyes simply by my uttering the names of the Lord? When will Lord Nityānanda have mercy upon me and make all my desires for material enjoyment insignificant? When shall I be purified by giving up all contaminations of material enjoyment? And when shall I be able to see the transcendental abode, Vṛndāvana? When shall I be eager to accept the Six Gosvāmīs as my prime guides? And when will I be able to understand the conjugal love of Kṛṣṇa?" No one should be eager to understand the conjugal love of Kṛṣṇa without undergoing disciplinary training under the Six Gosvāmīs of Vṛndāvana.
(Teachings of Lord Caitanya).

All the pastimes of the Supreme Lord in the spiritual world are eternal. His earthly pastimes are similarly transcendental and eternal. As the Caitanya-bhāgavata states, "Even at this very moment Lord Gaurāṅga is enacting His eternal, transcendental pastimes, but only the most fortunate souls can see them." When the sun sets, it goes out of our sight, but it continues to shine somewhere on this globe. Similarly, when the Lord winds up His earthly pastimes, He continues to manifest them in one or more of the uncountable millions of planets in the universe.
