The Eighth Chapter of Śrī Caitanya-caritāmṛta is summarized by Śrīla Bhaktivinoda Ṭhākura in his Amṛta-pravāha-bhāṣya. In this chapter the glories of Śrī Caitanya Mahāprabhu and Nityānanda are described, and it is also stated that one who commits offenses in chanting the Hare Kṛṣṇa mantra does not achieve love of Godhead, even after chanting for many years. In this connection, Śrīla Bhaktivinoda Ṭhākura warns against artificial displays of the bodily symptoms called aṣṭa-sāttvika-vikāra. (CC.3:14:99) That is also an offense. One should seriously and sincerely continue to chant the Pañca-tattva names śrī-kṛṣṇa-caitanya prabhu-nityānanda śrī-advaita gadādhara śrīvāsādi-gaura-bhakta-vṛnda. All these ācāryas will bestow their causeless mercy upon a devotee and gradually purify his heart. When he is actually purified, automatically he will experience ecstasy in chanting the Hare Kṛṣṇa mahā-mantra. Previous to the composition of Śrī Caitanya-caritāmṛta, Śrīla Vṛndāvana dāsa Ṭhākura wrote a book called Śrī Caitanya-bhāgavata. Only those subjects which were not discussed by Śrīla Vṛndāvana dāsa Ṭhākura in his Caitanya-bhāgavata have been taken up by Kṛṣṇadāsa Kavirāja Gosvāmī to be depicted in Śrī Caitanya-caritāmṛta. In his very old age, Kṛṣṇadāsa Kavirāja Gosvāmī went to Vṛndāvana, and by the order of Śrī Madana-mohanajī he wrote Śrī Caitanya-caritāmṛta. Thus we are now able to relish its transcendental bliss.
(Sri Caitanya Caritamrta-----1:8---summary).

A summary of Chapter Nine has been given as follows by Śrīla Bhaktivinoda Ṭhākura in his Amṛta-pravāha-bhāṣya. In this chapter the author of Śrī Caitanya-caritāmṛta has devised a figurative example by describing "the desire tree of bhakti." He considers Lord Caitanya Mahāprabhu, who is known as Viśvambhara, to be the gardener of this tree because He is the main personality who has taken charge of it. As the supreme enjoyer, He enjoyed the fruits Himself and distributed them as well. The seed of the tree was first sown in Navadvīpa, the birth site of Lord Caitanya Mahāprabhu, and then the tree was brought to Puruṣottama-kṣetra (Jagannātha Purī), and then to Vṛndāvana. The seed fructified first in Śrīla Mādhavendra Purī, and then in his disciple Śrī Īśvara Purī. It is figuratively described that both the tree itself and the trunk of the tree are Śrī Caitanya Mahāprabhu. Paramānanda Purī and eight other great sannyāsīs are like the spreading roots of the tree. From the main trunk there extend two special branches, Advaita Prabhu and Śrī Nityānanda Prabhu, and from those branches grow other branches and twigs.
(Sri Caitanya Caritamrta-----1:9---summary).

Bhaktivinoda Ṭhākura gives a summary of the Twelfth Chapter in his Amṛta-pravāha-bhāṣya. The Twelfth Chapter describes the followers of Advaita Prabhu, among whom the followers of Acyutānanda, the son of Advaita Ācārya, are understood to be the pure followers who received the cream of the philosophy Śrī Advaita Ācārya enunciated. Other so-called descendants and followers of Advaita Ācārya are not to be recognized. This chapter also includes narrations concerning the son of Advaita Ācārya named Gopāla Miśra and Advaita Ācārya's servant named Kamalākānta Viśvāsa. In his early life Gopāla fainted during the cleansing of the Guṇḍicā-mandira at Jagannātha Purī and thus became a recipient of the mercy of Lord Caitanya Mahāprabhu. The story of Kamalākānta Viśvāsa concerns his borrowing three hundred rupees from Pratāparudra Mahārāja to clear a debt of Advaita Ācārya's, for which Śrī Caitanya Mahāprabhu chastised him when He came to know of it. Kamalākānta Viśvāsa was then purified by the request of Śrī Advaita Ācārya. After describing the descendants of Advaita Ācārya, the chapter concludes by describing the followers of Gadādhara Paṇḍita Gosvāmī.
(Sri Caitanya Caritamrta-----1:12---summary).

The descendants of Advaita Ācārya who accepted the path of Śrī Acyutānanda were all great devotees.
In this connection, Śrīla Bhaktivinoda Ṭhākura, in his Amṛta-pravāha-bhāṣya, gives this short note: “Śrī Advaita Ācārya is one of the important trunks of the bhakti-kalpataru, or desire tree of devotional service. Lord Śrī Caitanya Mahāprabhu, as a gardener, poured water on the root of the bhakti tree and thus nourished all its trunks and branches. But nevertheless, under the spell of māyā, the most unfortunate condition of a living entity, some of the branches, not accepting the gardener who poured water on them, considered the trunk the only cause of the great bhakti-kalpataru. In other words, the branches or descendants of Advaita Ācārya who considered Advaita Ācārya the original cause of the devotional creeper, and who thus neglected or disobeyed the instructions of Śrī Caitanya Mahāprabhu, deprived themselves of the effect of being watered and thus dried up and died.
(Sri Caitanya Caritamrta-----1:12:73-----translation and purport).

Śrīla Bhaktivinoda Ṭhākura has given a summary of this chapter in his Amṛta-pravāha-bhāṣya: "In the Fourteenth Chapter there is a description of how Lord Caitanya Mahāprabhu enjoyed His childhood pastimes—crawling, crying, eating dirt and giving intelligence to His mother, favoring a brāhmaṇa guest, riding on the shoulders of two thieves and misleading them to His own house, and, on the plea of being diseased, taking prasādam in the house of Hiraṇya and Jagadīśa on the Ekādaśī day. The chapter further describes how He displayed Himself as a naughty boy, how when His mother fainted He brought a coconut to her on His head, how He joked with girls of the same age on the banks of the Ganges, how He accepted worshipful paraphernalia from Śrīmatī Lakṣmīdevī, how He sat down in a garbage pit and instructed His mother in transcendental knowledge, how He left the pit on the order of His mother, and how He dealt with His father with full affection."
(Sri Caitanya Caritamrta-----1:14---summary).

Hearing this, Lord Caitanya Mahāprabhu taught His mother about absolute knowledge. Although amazed by this, His mother forced Him to take a bath.
The absolute knowledge explained by the Lord to His mother is described by Śrīla Bhaktivinoda Ṭhākura in his Amṛta-pravāha-bhāṣya as follows: “The Lord said, "Mother, that this is pure and that is impure is surely a worldly sentiment with no basis in fact. You have cooked food for Lord Viṣṇu within these pots and offered the food to Him. How then can these pots be untouchable? Everything in relationship with Viṣṇu is to be considered an expansion of Viṣṇu"s energy. Viṣṇu, the Supersoul, is eternal and uncontaminated. How then may these pots be considered pure or impure?’ Hearing this discourse on absolute knowledge, His mother was very much astonished and forced Him to take a bath.”
(Sri Caitanya Caritamrta-----1:14:75-----translation and purport).

The Seventeenth Chapter, as summarized by Śrīla Bhaktivinoda Ṭhākura in his Amṛta-pravāha-bhāṣya, describes Lord Caitanya Mahāprabhu's pastimes from His sixteenth year until the time He accepted the renounced order of life. Śrīla Vṛndāvana dāsa Ṭhākura has already vividly described these pastimes in the Caitanya-bhāgavata; therefore Kṛṣṇa dāsa Kavirāja Gosvāmī describes them only briefly. Vivid descriptions of some portions of His pastimes are seen in this chapter, however, because Vṛndāvana dāsa Ṭhākura has not elaborately described them.
In this chapter we shall find descriptions of the mango distribution festival and Lord Caitanya's discourses with Chand Kazi. Finally, the chapter shows that the same son of mother Yaśodā, Lord Kṛṣṇa, tasted four transcendental mellows of devotional service in His form of Śacīnandana, the son of mother Śacī. To understand Śrīmatī Rādhārāṇī’s ecstatic love for Him, Lord Śrī Kṛṣṇa assumed the form of Lord Caitanya Mahāprabhu. The attitude of Śrīmatī Rādhārāṇī is considered the superexcellent devotional mentality. As Caitanya Mahāprabhu, Kṛṣṇa Himself assumed the position of Śrīmatī Rādhārāṇī to taste Her ecstatic situation. No one else could do this.
(Sri Caitanya Caritamrta-----1:17---summary).

Śrī Caitanya Mahāprabhu caused the dead son to speak about knowledge, and then the two brothers personally became the sons of Śrīvāsa Ṭhākura.
This incident is described as follows by Śrīla Bhaktivinoda Ṭhākura in his Amṛta-pravāha-bhāṣya. One night while Śrī Caitanya Mahāprabhu was dancing with His devotees at the house of Śrīvāsa Ṭhākura, one of Śrīvāsa Ṭhākura's sons, who was suffering from some disease, died. Śrīvāsa Ṭhākura was so patient, however, that he did not allow anyone to express sorrow by crying, for he did not want the kīrtana going on at his house to be disturbed. Thus kīrtana continued without a sound of lamentation. But when the kīrtana was over, Caitanya Mahāprabhu, who could understand the incident, declared, "There must have been some calamity in this house." When He was then informed about the death of Śrīvāsa Ṭhākura's son, He expressed His regret, saying, "Why was this news not given to Me before?" He went to the place where the son was lying dead and asked him, "My dear boy, why are you leaving the house of Śrīvāsa Ṭhākura?" The dead son immediately replied, "I was living in this house as long as I was destined to live here. Now that the time is over, I am going elsewhere, according to Your direction. I am Your eternal servant, a dependent living being. I must act only according to Your desire. Beyond Your desire, I cannot do anything. I have no such power."
