In the First Wave of the book known as the Bhakti-ratnākara, it is said that Sanātana Gosvāmī understood Śrīmad-Bhāgavatam by thorough study and explained it in his commentary known as Vaiṣṇava-toṣaṇī. All the knowledge that Śrī Sanātana Gosvāmī and Rūpa Gosvāmī directly acquired from Śrī Caitanya Mahāprabhu was broadcast all over the world by their expert service. Sanātana Gosvāmī gave his Vaiṣṇava-toṣaṇī commentary to Śrīla Jīva Gosvāmī for editing, and Śrīla Jīva Gosvāmī edited this under the name of Laghu-toṣaṇī. Whatever he immediately put down in writing was finished in the year 1476 Śaka (A.D. 1554). Śrīla Jīva Gosvāmī completed the Laghu-toṣaṇī in the year Śakābda 1504 (A.D. 1582).

Regarding the Bṛhad-bhāgavatāmṛta, there are two parts, both of which deal with the discharge of devotional service. The first part is an analytical study of devotional service, in which there is also a description of different planets, including the earth, the heavenly planets, Brahma-loka and Vaikuṇṭha-loka. There are also descriptions of the devotees, including intimate devotees, most intimate devotees and complete devotees. The second part describes the glories of the spiritual world, known as Goloka-māhātmya-nirūpaṇa, as well as the process of renunciation of the material world. It also describes real knowledge, devotional service, the spiritual world, love of Godhead, attainment of life's destination, and the bliss of the world. In this way there are seven chapters in each part, fourteen chapters in all.
The Daśama-ṭippanī is a commentary on the Tenth Canto of Śrīmad-Bhāgavatam. Another name for this commentary is Bṛhad-vaiṣṇava-toṣaṇī-ṭīkā. In the Bhakti-ratnākara, it is said that the Daśama-ṭippanī was finished in 1476 Śakābda (A.D. 1554).
(Sri Caitanya Caritamrta-----2:1:35-----purport).

According to śāstra, there are three kinds of birth. The first birth is from the womb of the mother, the second birth is the acceptance of the reformatory method, and the third birth is acceptance by the spiritual master (initiation). One becomes abominable by adopting an abominable profession or by associating with people who are naturally abominable. Rūpa and Sanātana, as Dabira Khāsa and Sākara Mallika, associated with Muslims, who were naturally opposed to brahminical culture and cow protection. In Śrīmad-Bhāgavatam (Seventh Canto) it is stated that every person belongs to a certain classification. A person is identifiable by the special symptoms mentioned in the śāstras. By one's symptoms, one is known to belong to a certain caste. Both Dabira Khāsa and Sākara Mallika belonged to the brāhmaṇa caste, but because they were employed by Muslims, their original habits degenerated into those of the Muslim community. Since the symptoms of brahminical culture were almost nil, they identified themselves with the lowest caste. In the Bhakti-ratnākara it is clearly stated that because Sākara Mallika and Dabira Khāsa associated with lower-class men, they introduced themselves as belonging to the lower classes. Actually, however, they had been born in respectable brāhmaṇa families.
(Sri Caitanya Caritamrta-----2:1:189-----purport).

Śrī Veṅkaṭa Bhaṭṭa was a Vaiṣṇava brāhmaṇa and an inhabitant of Śrī Raṅga-kṣetra. He belonged to the disciplic succession of Śrī Rāmānujācārya. Śrī Raṅga is one of the places of pilgrimage in the province of Tamil Nadu. The inhabitants of that province do not retain the name Veṅkaṭa. It is therefore supposed that Veṅkaṭa Bhaṭṭa did not belong to that province, although he may have been residing there for a very long time. Veṅkaṭa Bhaṭṭa was in a branch of the Rāmānuja-sampradāya known as Vaḍagalai. He had a brother in the Rāmānuja-sampradāya known as Śrīpāda Prabodhānanda Sarasvatī. The son of Veṅkaṭa Bhaṭṭa was later known in the Gauḍīya-sampradāya as Gopāla Bhaṭṭa Gosvāmī, and he established the Rādhāramaṇa temple in Vṛndāvana. More information about him may be found in a book known as the Bhakti-ratnākara, by Narahari Cakravartī.
(Sri Caitanya Caritamrta-----2:9:82-----purport).

In the commentary of Premadāsa it is said:
nadīyāra mājhakhāne, sakala lokete
jāne, "kuliyā-pāhāḍapura" nāme sthāna
"Everyone knows that in the middle of Nadia is a village named Kuliyā-pāhāḍapura."
Śrī Narahari Cakravartī, or Ghanaśyāma dāsa, has written in his Bhakti-ratnākara:
kuliyā pāhāḍapura dekha śrīnivāsa
pūrve "koladvīpa"-parvatākhya—e pracāra
"He said, "O Śrīnivāsa, just see the town of Kuliyā-pāhāḍapura, which was previously known as Koladvīpa.""
In a book named Navadvīpa-dhāma-parikramā, also written by Ghanaśyāma dāsa, it is stated: kuliyā-pāhāḍapura grāma pūrve koladvīpa-parvatākhyānanda nāma. "The town of Kuliyā-pāhāḍapura was previously named Koladvīpa-parvatākhyānanda."
Therefore one can conclude that the present-day city of Navadvīpa and the places known as Bāhiradvīpa, Kolera Gañja, Kola-āmāda, Kolera Daha, Gadakhāli, etc., were known as Kuliyā, but the so-called Kuliyāra Pāḍa is not the original Kuliyā.
(Sri Caitanya Caritamrta-----2:16:207-----purport).

The village named Annakūṭa-grāma is referred to in the Bhakti-ratnākara (Fifth Wave):
gopa-gopī bhuñjāyena kautuka apāra
ei hetu "āniyora" nāma se ihāra
annakūṭa-sthāna ei dekha śrīnivāsa
e-sthāna darśane haya pūrṇa abhilāṣa
"Here all the gopīs and the gopas enjoyed wonderful pastimes with Śrī Kṛṣṇa. Therefore this place is also called Āniyora. The Annakūṭa ceremony was celebrated here. O Śrīnivāsa, whoever sees this place has all his desires fulfilled." It is also stated:
kuṇḍera nikaṭa dekha niviḍa-kānana
ethāi "gopāla" chilā hañā saṅgopana
"Look at the dense forest near the kuṇḍa. It was there that Gopāla was concealed."
(Sri Caitanya Caritamrta-----2:18:26-----purport).

Śrīla Bhaktisiddhānta Sarasvatī Ṭhākura gives the following information about Govinda-kuṇḍa. There is a village named Āniyora on Govardhana Hill, a little distance from the village of Paiṭhā. Govinda-kuṇḍa is situated near here, and there are two temples to Govinda and Baladeva there. According to some, Queen Padmāvatī excavated this lake. In the Bhakti-ratnākara (Fifth Wave), the following statement is found:
ei śrī-govinda-kuṇḍa-mahimā aneka
ethā indra kaila govindera abhiṣeka
"Govinda-kuṇḍa is exalted for its many spiritual activities. It was here that Indra, defeated by Lord Govinda, offered prayers to Him and bathed Him."
(Sri Caitanya Caritamrta-----2:18:37-----purport).

"Simply by bathing in Govinda-kuṇḍa, one is awarded liberation. This lake was produced when Bhagavān Śrī Kṛṣṇa was bathed by Lord Indra."
Gāṅṭhuli-grāma is situated near the two villages Bilachu and Gopāla-pura. According to hearsay, Rādhā and Kṛṣṇa first met here. In the Bhakti-ratnākara (Fifth Wave), it is stated, sakhī duṅha vastre gāṅṭhi dila saṅgopane: "The two concealed Themselves by tying Their outer garments together." It is also stated, phāguyā laiyā keha gāṅṭhi khuli' dilā: "With a phāguyā They undid the knot." For this reason the village is known as Gāṅṭhuli.
(Sri Caitanya Caritamrta-----2:18:37-----purport).

When the two brothers Śrīla Rūpa Gosvāmī and Sanātana Gosvāmī went to Vṛndāvana, they decided to live there. Following Śrī Caitanya Mahāprabhu's example, they did not climb the hill because they considered it nondifferent from Kṛṣṇa, the Supreme Personality of Godhead. On some pretext, the Gopāla Deity granted Śrī Caitanya Mahāprabhu an audience beneath the hill, and Gopāla similarly favored Śrīla Rūpa Gosvāmī and Sanātana Gosvāmī. During his ripe old age, when Rūpa Gosvāmī could not go to Govardhana Hill because of invalidity, Gopāla kindly went to Mathurā and remained at the house of Viṭhṭhaleśvara for one month. It was then that Śrīla Rūpa Gosvāmī could see Gopāla's beauty to his heart's content.
The following description concerning Viṭhṭhaleśvara is given in the Bhakti-ratnākara (Fifth Wave).
(Sri Caitanya Caritamrta-----2:18:47-----purport).

Laghu Haridāsa should not be confused with Junior Haridāsa, who committed suicide at Prayāga. Generally a devotee is called Haridāsa, and consequently there are many Haridāsas. The chief was Ṭhākura Haridāsa. There was also a Madhyama Haridāsa.
In the Bhakti-ratnākara (Sixth Wave), there is a list of many of the chief devotees who accompanied Śrīla Rūpa Gosvāmī.
(Sri Caitanya Caritamrta-----2:18:52-----purport).

Kāmyavana is mentioned in the Ādi-varāha Purāṇa:
caturthaṁ kāmyaka-vanaṁ vanānāṁ vanam uttamam
tatra gatvā naro devi mama loke mahīyate
Lord Śiva said, "The best of all forests is the fourth of these, named Kāmyaka. O goddess Devī, any person who goes there is eligible to enjoy the glories of my abode."
In the Bhakti-ratnākara (Fifth Wave) it is also said:
ei kāmyavane kṛṣṇa-līlā manohara
karibe darśana sthāna kuṇḍa bahutara
kāmyavane yata tīrtha lekhā nāhi tāra
"In this Kāmyavana, Kṛṣṇa performed enchanting pastimes. Here you will be able to take darśana of many ponds and other transcendental spots. I cannot even describe in writing all the sacred tīrthas found at Kāmyavana."
(Sri Caitanya Caritamrta-----2:18:55-----purport).

Of Śrīvana (also called Bilvavana), the Bhakti-ratnākara states, devatā-pūjita bilvavana śobhāmaya: "The beautiful forest of Bilvavana is worshiped by all the demigods."
About Lohavana, the Bhakti-ratnākara (Fifth Wave) states:
lohavane kṛṣṇera adbhuta go-cāraṇa
ethā loha-jaṅghāsure vadhe bhagavān
"At Lohavana, Lord Kṛṣṇa used to tend cows. The demon named Lohajaṅgha was killed at this place."
Mahāvana is described as follows in the Bhakti-ratnākara (Fifth Wave):
dekha nanda-yaśodā-ālaya mahāvane
ei dekha śrī-kṛṣṇa-candrera janma sthala
śrī-gokula, mahāvana—dui "eka" haya
"Behold the house of Nanda and Yaśodā in Mahāvana. See the birthplace of Lord Kṛṣṇa. Mahāvana and the birthplace of Lord Kṛṣṇa, Gokula, are one and the same."
(Sri Caitanya Caritamrta-----2:18:67-----purport).

The Bhakti-ratnākara refers to the following books by Śrīla Sanātana Gosvāmī: (1) the Bṛhad-bhāgavatāmṛta, (2) the Hari-bhakti-vilāsa and his commentary known as Dig-darśinī, (3) the Līlā-stava and (4) the commentary on the Tenth Canto of Śrīmad-Bhāgavatam known as Vaiṣṇava-toṣaṇī. Sanātana Gosvāmī compiled many, many books, all with the aim of describing how to serve the principal Deities of Vṛndāvana—Govinda and Madana-gopāla. Later, other Deities were gradually established, and the importance of Vṛndāvana increased.
(Sri Caitanya Caritamrta-----3:4:222-----purport).

Referring to the words lakṣa-grantha ("100,000 verses"), Śrīla Bhaktisiddhānta Sarasvatī Ṭhākura says that the total number of verses written by Śrīla Rūpa Gosvāmī is 100,000 (eka-lakṣa or lakṣa-grantha). The copyists count both the verses and the prose sections of the Sanskrit works. One should not mistakenly think that Śrīla Rūpa Gosvāmī compiled 100,000 books. He actually wrote sixteen books, as mentioned in the First Wave of the Bhakti-ratnākara (śrī-rūpa-gosvāmī grantha ṣoḍaśa karila).
(Sri Caitanya Caritamrta-----3:4:226-----purport).

At Puruṣottama-kṣetra, or Jagannātha Purī, there is a temple of Ṭoṭā-gopīnātha. If one goes from there to the sea, he can discover the tomb of Haridāsa Ṭhākura still existing. Every year on the date of Ananta-caturdaśī there is a festival to commemorate the passing away of Haridāsa Ṭhākura. At the same place, Deities of Nityānanda Prabhu, Kṛṣṇa Caitanya Mahāprabhu and Advaita Prabhu were established about one hundred years ago. A gentleman named Bhramaravara from Kendrāpāḍā, in the province of Orissa, contributed funds to establish these Deities in the temple. The management of the temple was under the Ṭoṭā-gopīnātha gosvāmīs.
This temple was later sold to someone else, and this party is now maintaining the sevā-pūjā of the temple. Near this temple and the tomb of Haridāsa Ṭhākura, Śrīla Bhaktivinoda Ṭhākura constructed a small house called the Bhakti-kuṭī. In the Bengali year 1329 (A.D. 1922), the Puruṣottama-maṭha, a branch of the Gauḍīya Maṭha, was established there. In the Bhakti-ratnākara it is stated:
śrīnivāsa śīghra samudrera kūle gelā
haridāsa-ṭhākurera samādhi dekhilā
bhūmite paḍiyā kailā praṇati vistara
bhāgavata-gaṇa śrī-samādhi-sannidhāne
śrīnivāse sthira kailā sasneha-vacane
punaḥ śrīnivāsa śrī-samādhi praṇamiyā
ye vilāpa kailā, tā śunile drave hiyā
“Śrīnivāsa Ṭhākura quickly ran to the seashore. When he saw the tomb of Haridāsa Ṭhākura, he immediately fell down offering prayers and almost fainted. The devotees present there pacified him with very sweet and affectionate words, and Śrīnivāsa again offered his obeisances to the tomb. Hearing of the separation that Śrīnivāsa expressed in his lamentation at the tomb of Haridāsa Ṭhākura makes one's heart melt.”
(Sri Caitanya Caritamrta-----3:11:101-----purport).
