Srila Prabhupada
Just like Caitanya Mahāprabhu. There was a devotee of Caitanya Mahāprabhu. His name was Murāri Gupta. He was physician to the then Nawab, Muslim Nawab. Now, they were sitting. The Nawab was going some hunting excursion or something like that, but he was Nawab's physician. He was to accompany him. So they were sitting on the back of the elephant. In the meantime, that Murāri Gupta saw one peacock, and as soon as he saw the peacock, the feather, he at once remembered Kṛṣṇa and at once fainted and fall down. This is called ālambana. This is called ālambana. Ālambana means anything to the context, immediately he remembers his Lord and becomes ecstatic. This is the first-class stage of Kṛṣṇa consciousness. So there are many instances. Caitanya Mahāprabhu showed this manifestation in His life.

Although there is no difference between Rāma and Kṛṣṇa, some devotees are attracted with rāma-mūrti and some devotees are attracted with kṛṣṇa-mūrti. But factually there is no difference.
But in the śāstras it is said that if you chant the name of Viṣṇu, viṣṇu-sahasra-nāma, by chanting one thousand times Lord Viṣṇu's name is equal to one name of Rāma. And by chanting three times the name of Lord Rāma it is equal to one name of Kṛṣṇa. This is the verdict of the śāstra. So when we chant Hare Kṛṣṇa, Rāma is there already, three times. It is not that because we are chanting Hare Kṛṣṇa we are neglecting Rāma. No. With each Kṛṣṇa name there are three times Rāma name. That is the verdict of the śāstra.
Besides that, we are chanting also Hare Rāma. Hare Rāma and Sītā-Rāma the same thing. Hare Kṛṣṇa, Hare Kṛṣṇa or Hare Rāma, Hare Rāma, there is no difference. This is also rāma-dhun, Hare Rāma, Hare Rāma, Rāma Rāma, Hare Hare. In the śāstras it is recommended, Agni Purāṇa, Brahmāṇḍa Purāṇa, Kali-santaraṇa Upaniṣad the:
Hare Kṛṣṇa Hare Kṛṣṇa Kṛṣṇa Kṛṣṇa Hare Hare
Hare Rāma Hare Rāma Rāma Rāma Hare Hare
Besides that, when we chant Kṛṣṇa's name, we chant also Lord Rāma's name. Just like in the prayer offered by Śrī Caitanya Mahāprabhu:
kṛṣṇa kṛṣṇa kṛṣṇa kṛṣṇa
kṛṣṇa kṛṣṇa kṛṣṇa he
kṛṣṇa kṛṣṇa kṛṣṇa kṛṣṇa
kṛṣṇa kṛṣṇa kṛṣṇa he
kṛṣṇa kṛṣṇa kṛṣṇa kṛṣṇa
kṛṣṇa kṛṣṇa rakṣa mām
kṛṣṇa kṛṣṇa kṛṣṇa kṛṣṇa
kṛṣṇa kṛṣṇa pāhi mām
rāma rāghava rāma rāghava
rāma rāghava rakṣa mām
kṛṣṇa keśava kṛṣṇa keśava
kṛṣṇa keśava pāhi mām
So devotees, they always chant together Kṛṣṇa's name and Rāma's name.

Rāmacandra, Lord Rāmacandra appeared on this world to educate, or to place ideal example of a king, how the king should be. Therefore when there is good government . . . the example is given, Rāma-rājya. Rāma-rājya. It is the kingdom of Lord Rāma. Because everyone was happy. Everyone. There are so many instances in the life of Rāmacandra.

Caitanya means living. That personification of all living forces is Kṛṣṇa Caitanya, Śrī Caitanya Mahāprabhu. People mistake Kṛṣṇa Caitanya Mahāprabhu because by misfortune they understand Kṛṣṇa Caitanya as a devotee or just like so-called sādhu or yogī, like that. That is mistake. Kṛṣṇa Caitanya means the original living force, Kṛṣṇa. So Sārvabhauma Bhaṭṭācārya, he understood Him. Śrīla Rūpa Gosvāmī, he understood Him. Similarly, the followers of Rūpa Gosvāmī—Sārvabhauma Bhaṭṭācārya, and all the Gosvāmīs—they will understand Kṛṣṇa Caitanya Mahāprabhu. And one who understands or follows the path enunciated by Kṛṣṇa Caitanya Mahāprabhu, for them Kṛṣṇa is very easily obtained. This is called Caitanya-caritāmṛta.

Caitanya-caritāmṛta is the postgraduate study of Kṛṣṇa consciousness. The Bhagavad-gītā is the A-B-C-D to entrance, and Śrīmad-Bhāgavatam is the graduate study, and Śrī–Caitanya-caritāmṛta is the postgraduate study of spiritual life. My Guru Mahārāja, His Divine Grace Bhaktisiddhānta Sarasvatī Gosvāmī Prabhupāda, whenever he got some time he used to read Caitanya-caritāmṛta. And he predicted that the whole world like to read Caitanya-caritāmṛta, and for this reason they’ll learn Bengali. Therefore, following his footsteps, I have kept the Bengali character and tried to give the literary meaning of each word of the Bengali poem. This is, of course, Sanskrit. This book is full of Sanskrit verses. Some of them are composed by the author himself, Kavirāja Gosvāmī, and some of them are quoted from various literature, Vedic literature.
