Kavirāja Gosvāmī states as follows:
ataeva kṛṣṇa mūla-jagat-kāraṇa
prakṛti—kāraṇa yaiche ajā-gala-stana
(CC.1:5:61)
Because Kāraṇārṇavaśāyī Viṣṇu is a plenary expansion of Kṛṣṇa, it is He who electrifies the matter to put it in motion. The example of electrification is quite appropriate. A piece of iron is certainly not fire, but when the iron is made red-hot, certainly it has the quality of fire through its burning capacity. Matter is compared to the piece of iron, and it is electrified or made red-hot by the glance or manipulation of the supreme consciousness of Viṣṇu. Only by such electrification is the energy of matter displayed in various actions and reactions. Therefore the inert matter is neither efficient nor the material cause of the cosmic manifestation.
(Srimad Bhagavatam------2:10:45-------purport).

Kṛṣṇadāsa Kavirāja lists the following twenty-six good qualities of a Vaiṣṇava: (1) He is very kind to everyone. (2) He does not make anyone his enemy. (3) He is truthful. (4) He is equal to everyone. (5) No one can find any fault in him. (6) He is magnanimous. (7) He is mild. (8) He is always clean. (9) He is without possessions. (10) He works for everyone's benefit. (11) He is very peaceful. (12) He is always surrendered to Kṛṣṇa. (13) He has no material desires. (14) He is very meek. (15) He is steady. (16) He controls his senses. (17) He does not eat more than required. (18) He is not influenced by the Lord's illusory energy. (19) He offers respect to everyone. (20) He does not desire any respect for himself. (21) He is very grave. (22) He is merciful. (23) He is friendly. (24) He is poetic. (25) He is expert. (26) He is silent.
(Srimad Bhagavatam------5:18:12-------purport).

Similarly, in Caitanya-caritāmṛta, Kṛṣṇadāsa Kavirāja Gosvāmī says that since Śrī Caitanya Mahāprabhu is the inaugurator of the saṅkīrtana movement, anyone who performs saṅkīrtana to please the Lord is very, very glorious. Such a person has perfect intelligence, whereas others are in the ignorance of material existence. Of all the sacrifices mentioned in the Vedic literatures, the performance of saṅkīrtana-yajña is the best. Even the performance of one hundred aśvamedha sacrifices cannot compare to the sacrifice of saṅkīrtana.
(Srimad Bhagavatam------5:19:24-------purport).

In the beginning of the Caitanya-caritāmṛta, Kṛṣṇadāsa Kavirāja Gosvāmī writes, "I offer my respects to my spiritual masters." He uses the plural here to indicate the disciplic succession. He offers obeisances not to his spiritual master alone but to the whole paramparā, the chain of disciplic succession beginning with Lord Kṛṣṇa Himself. Thus the author addresses the guru in the plural to show the highest respect for all his predecessor spiritual masters.
(Sri Caitanya Caritamrta------introduction).

In the Western world, where the glories of Lord Caitanya are relatively unknown, one may inquire, "Who is Kṛṣṇa Caitanya?" The author of the Caitanya-caritāmṛta, ŚrīlaKṛṣṇadāsa Kavirāja, answers that question in the third verse of his book. Generally, in the Upaniṣads the Supreme Absolute Truth is described in an impersonal way, but the personal aspect of the Absolute Truth is mentioned in the Īśopaniṣad, where we find the following verse:
hiraṇmayena pātreṇa satyasyāpihitaṁ mukham
tat tvaṁ pūṣann apāvṛṇu satya-dharmāya dṛṣṭaye
"O my Lord, sustainer of all that lives, Your real face is covered by Your dazzling effulgence. Kindly remove that covering and exhibit Yourself to Your pure devotee." (Śrī Īśopaniṣad 15)
(Sri Caitanya Caritamrta------introduction).

With verse 15, Kṛṣṇadāsa Kavirāja Gosvāmī begins offering his obeisances directly to Kṛṣṇa Himself. Kṛṣṇadāsa Kavirāja 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. He worshiped Rādhā-Kṛṣṇa with his family, and once when there was some misunderstanding among his family members about devotional service, he 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 the 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 Mahāprabhu's philosophy and life.
(Sri Caitanya Caritamrta------introduction).

When Kṛṣṇadāsa Kavirāja Gosvāmī was living in Vṛndāvana, there were not very many temples. At that time the three principal temples were those of Madana-mohana, Govindajī and Gopīnātha. As a resident of Vṛndāvana, Kṛṣṇadāsa Kavirāja offers his respects to the Deities in these temples and requests God's favor: “My progress in spiritual life is very slow, so I’m asking Your help.”
(Sri Caitanya Caritamrta------introduction).

Kṛṣṇadāsa offers his obeisances to the Madana-mohana vigraha, the Deity who can help us progress in Kṛṣṇa consciousness. In the execution of Kṛṣṇa consciousness, our first business is to know Kṛṣṇa and our relationship with Him. To know Kṛṣṇa is to know one's self, and to know one's self is to know one's relationship with Kṛṣṇa. Since this relationship can be learned by worshiping the Madana-mohana vigraha, Kṛṣṇadāsa Kavirāja Gosvāmī first establishes his relationship with Him.
(Sri Caitanya Caritamrta------introduction).

Kṛṣṇadāsa Kavirāja Gosvāmī says that Nandasuta has again appeared as Lord Śrī Kṛṣṇa Caitanya Mahāprabhu, and he bases this statement on his understanding that the Vedic literature concludes there is no difference between Lord Kṛṣṇa and Lord Caitanya Mahāprabhu. This the author will prove. If it is thus proved that Śrī Kṛṣṇa is the origin of all tattvas (truths), namely Brahman, Paramātmā and Bhagavān, and that there is no difference between Śrī Kṛṣṇa and Lord Śrī Caitanya Mahāprabhu, it will not be difficult to understand that Śrī Caitanya Mahāprabhu is also the same origin of all tattvas. The same Absolute Truth, as He is revealed to students of different realizations, is called Brahman, Paramātmā and Bhagavān.
(Sri Caitanya Caritamrta--------1:2:9------purport).

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

The author of the Caitanya-caritāmṛta, Kṛṣṇadāsa Kavirāja Gosvāmī, left his home because of his brother's stressing the importance of Śrī Caitanya Mahāprabhu over that of Nityānanda Prabhu. Actually, one should offer respect to the Pañca-tattva without such foolish discrimination, not considering Nityānanda Prabhu to be greater, Caitanya Mahāprabhu to be greater or Advaita Prabhu to be greater. The respect should be offered equally: śrī-kṛṣṇa-caitanya prabhu-nityānanda śrī-advaita gadādhara śrīvāsādi-gaura-bhakta-vṛnda. All devotees of Lord Caitanya or Nityānanda are worshipable persons.
(Sri Caitanya Caritamrta--------1:7:165------purport).

Kṛṣṇadāsa Kavirāja Gosvāmī confirms that what Vṛndāvana dāsa Ṭhākura wrote was actually spoken by Lord Caitanya Mahāprabhu, and he simply repeated it. The same holds true for Śrī Caitanya-caritāmṛta. Kṛṣṇadāsa Kavirāja Gosvāmī wrote Śrī Caitanya-caritāmṛta in his old age, in an invalid condition, but it is such a sublime literature that Śrīla Bhaktisiddhānta Sarasvatī Gosvāmī Mahārāja used to say, "The time will come when the people of the world will learn Bengali to read Śrī Caitanya-caritāmṛta." We are trying to present Śrī Caitanya-caritāmṛta in English and do not know how successful it will be, but if one reads the original Caitanya-caritāmṛta in Bengali he will relish increasing ecstasy in devotional service.
(Sri Caitanya Caritamrta--------1:8:39------purport).

Śrī Kṛṣṇadāsa Kavirāja Gosvāmī sets the example of offering obeisances to all the preacher devotees of Lord Caitanya, without distinction as to higher and lower. Unfortunately, at present there are many foolish so-called devotees of Lord Caitanya who make such distinctions. For example, the title "Prabhupāda" is offered to a spiritual master, especially to a distinguished spiritual master such as Śrīla Rūpa Gosvāmī Prabhupāda, Śrīla Jīva Gosvāmī Prabhupāda or Śrīla Bhaktisiddhānta Sarasvatī Gosvāmī Prabhupāda. When our disciples similarly wanted to address their spiritual master as Prabhupāda, some foolish people became envious. Not considering the propaganda work of the Hare Kṛṣṇa movement, simply because these disciples addressed their spiritual master as Prabhupāda they became so envious that they formed a faction along with other such envious persons just to minimize the value of the Kṛṣṇa consciousness movement. To chastise such fools, Kṛṣṇadāsa Kavirāja Gosvāmī very frankly says, keha karibāre nāre jyeṣṭha-laghu-krama. Anyone who is a bona fide preacher of the cult of Śrī Caitanya Mahāprabhu must be respectful to the real devotees of Lord Caitanya; one should not be envious, considering one preacher to be very great and another to be very lowly. This is a material distinction and has no place on the platform of spiritual activities. Kṛṣṇadāsa Kavirāja Gosvāmī therefore offers equal respect to all the preachers of the cult of Śrī Caitanya Mahāprabhu, who are compared to the branches of the tree. ISKCON is one of these branches, and it should therefore be respected by all sincere devotees of Lord Caitanya Mahāprabhu.
(Sri Caitanya Caritamrta--------1:10:7------purport).

Śrīla Kṛṣṇadāsa Kavirāja Gosvāmī accepted Raghunātha dāsa Gosvāmī as his special guide. Therefore at the end of every chapter he says, śrī-rūpa-raghunātha-pade yāra āśa caitanya-caritāmṛta kahe kṛṣṇadāsa. Sometimes it is misunderstood that by using the word raghunātha he wanted to offer his respectful obeisances to Raghunātha Bhaṭṭa Gosvāmī, for it is sometimes stated that Raghunātha Bhaṭṭa Gosvāmī was his initiating spiritual master. Śrīla Bhaktisiddhānta Sarasvatī Gosvāmī does not approve of this statement; he does not accept Raghunātha Bhaṭṭa Gosvāmī as the spiritual master of Śrīla Kṛṣṇadāsa Kavirāja Gosvāmī.
(Sri Caitanya Caritamrta--------1:10:103------purport).

Kṛṣṇa's accepting the part of the gopīs is certainly contradictory according to any mundane calculations, but the Lord, by His inconceivable character, may act like the gopīs and feel separation from Kṛṣṇa, although He is Kṛṣṇa Himself. Such a contradiction can be reconciled only in the Supreme Personality of Godhead because He has energy that is inconceivable (acintya), which can make possible that which is impossible to do (aghaṭa-ghaṭana-patīyasī). Such contradictions are very difficult to understand unless a devotee strictly follows the Vaiṣṇava philosophy under the direction of the Gosvāmīs. Therefore Kṛṣṇadāsa Kavirāja Gosvāmī ends every chapter with this verse:

śrī-rūpa-raghunātha-pade yāra āśa
caitanya-caritāmṛta kahe kṛṣṇadāsa
"Praying at the lotus feet of Śrī Rūpa and Śrī Raghunātha, always desiring their mercy, I, Kṛṣṇadāsa, narrate Śrī Caitanya-caritāmṛta, following in their footsteps."
(Sri Caitanya Caritamrta--------1:7:304------purport).

The author of Śrī Caitanya-caritāmṛta, Kṛṣṇadāsa Kavirāja Gosvāmī, has condemned all his enemies by comparing them to envious hogs and pigs. The Kṛṣṇa consciousness movement, which is spreading throughout the world, is being appreciated by sincere people, although they have never previously heard of Śrī Caitanya Mahāprabhu and Kṛṣṇa's pastimes. Now even the higher, priestly circles are appreciating this movement. They have concluded that this movement is very nice and that they have something to learn from it. Nonetheless, in India there are some people who say that they belong to this cult but who are actually very envious of the ācārya. They have tried to suppress our activities in many ways, but as far as we are concerned, we follow in the footsteps of Kṛṣṇadāsa Kavirāja Gosvāmī and take them as envious pigs and hogs. We simply wish to present the pastimes of Lord Kṛṣṇa and Śrī Caitanya Mahāprabhu to the best of our ability so that those who are really honest can cleanse their hearts. We hope that they enjoy this literature and bestow their blessings upon us. It appears that even such a great personality as Kṛṣṇadāsa Kavirāja Gosvāmī met with some envious obstacles; what, then, to speak of us, who are only insignificant creatures in this universe. We are simply trying to execute the orders of our spiritual master to the best of our ability.
