In the Bhakti-rasāmṛta-sindhu, the word dainya (humility) is explained as follows: "When unhappiness, fearfulness and the sense of having offended combine, one feels condemned. This sense of condemnation is described as dīnatā, humility. When one is subjected to such humility, he feels physically inactive, he apologizes, and his consciousness is disturbed. His mind is also restless, and many other symptoms are visible." The word nirveda is also explained in the Bhakti-rasāmṛta-sindhu: “One may feel unhappiness and separation, as well as jealousy and lamentation, due to not discharging one's duties. The despondency that results is called nirveda. When one is captured by this despondency, thoughts, tears, loss of bodily luster, humility and heavy breathing result.” Viṣāda is also explained in the Bhakti-rasāmṛta-sindhu: "When one fails to achieve his desired goal of life and repents for all his offenses, there is a state of regret called viṣāda." The symptoms of avasāda are also explained: "One hankers to revive his original condition and inquires how to do so. There are also deep thought, heavy breathing, crying and lamentation, as well as a changing of the bodily color and drying up of the tongue."
In the Bhakti-rasāmṛta-sindhu thirty-three such destructive symptoms are mentioned. They are expressed in words, in the eyebrows and in the eyes. These symptoms are called vyabhicārī bhāva, destructive ecstasy. If they continue, they are sometimes called sañcārī, or continued ecstasy.

(Sri Caitanya Caritamrta-----2:2:63-----purport).

The word unmāda is explained in the Bhakti-rasāmṛta-sindhu as extreme joy, misfortune and bewilderment in the heart due to separation. Symptoms of unmāda are laughing like a madman, dancing, singing, performing ineffectual activities, talking nonsense, running, shouting and sometimes working in contradictory ways. The word praṇaya is explained thus: When there is a possibility of receiving direct honor but it is avoided, that love is called praṇaya. Śrīla Rūpa Gosvāmī, in his Ujjvala-nīlamaṇi, explains the word māna thus: When the lover feels novel sweetness by exchanging hearty loving words but wishes to hide his feelings by crooked means, māna is experienced.

In the Bhakti-rasāmṛta-sindhu, eight kinds of transcendental changes taking place in the body are described. Stambha, being stunned, refers to the mind's becoming transcendentally absorbed. In that state, the peaceful mind is placed on the life air, and different bodily transformations are manifest. These symptoms are visible in the body of an advanced devotee. When life becomes almost inactive, it is called "stunned." The emotions resulting from this condition are joy, fear, astonishment, moroseness and anger. In this condition, the power of speech is lost and there is no movement in the hands and legs. Otherwise, being stunned is a mental condition. Many other symptoms are visible on the entire body in the beginning. These are very subtle, but gradually they become very apparent. When one cannot speak, naturally one's active senses are arrested, and the knowledge-acquiring senses are rendered inoperative. Kampa, trembling of the body, is mentioned in the Bhakti-rasāmṛta-sindhu as a result of a special kind of fear, anger and joy.

These are very subtle, but gradually they become very apparent. When one cannot speak, naturally one's active senses are arrested, and the knowledge-acquiring senses are rendered inoperative. Kampa, trembling of the body, is mentioned in the Bhakti-rasāmṛta-sindhu as a result of a special kind of fear, anger and joy. This is called vepathu, or kampa. When the body begins to perspire because of joy, fear and anger combined, this is called sveda. Vaivarṇya is described as a change in the bodily color. It is caused by a combination of moroseness, anger and fear. When these emotions are experienced, the complexion turns pale and the body becomes lean and thin. Aśru is explained in the Bhakti-rasāmṛta-sindhu as a combination of joy, anger and moroseness that causes water to flow from the eyes without effort. When there is joy and there are tears in the eyes, the temperature of the tears is cold, but when there is anger, the tears are hot. In both cases, the eyes are restless, the eyeballs are red and there is itching. These are all symptoms of aśru. When there is a combination of moroseness, astonishment, anger, joy and fear, there is a choking in the voice. This choking is called gadgada. Śrī Caitanya Mahāprabhu refers to gadgada-ruddhayā girā, or "a faltering voice." In the Bhakti-rasāmṛta-sindhu, pulaka is described as joy, encouragement and fear. When these combine, the hairs on the body stand on end, and this bodily state is called pulaka.
(Sri Caitanya Caritamrta-----2:2:72-----purport).

Harṣa is described in the Bhakti-rasāmṛta-sindhu. Harṣa is experienced when one finally attains the desired goal of life and consequently becomes very glad. When harṣa is present, the body shivers, and one's bodily hairs stand on end. There are perspiration, tears and an outburst of passion and madness. The mouth becomes swollen, and one experiences inertia and illusion. When a person attains his desired object and feels very fortunate, the luster of his body increases. Because of his own qualities and feelings of greatness, he does not care for anyone else, and this is called garva, or pride. In this condition one utters prayers and does not reply to others' inquiries. Looking at one's own body, concealing one's desires and not heeding the words of others are symptoms visible in the ecstasy of garva.
(Sri Caitanya Caritamrta-----2:3:127-----purport).

Devastation is described in the Bhakti-rasāmṛta-sindhu as a combination of happiness and distress that becomes conspicuous by an absence of any sense of them. In this condition, a devotee falls to the ground, and the subsequent symptoms in the body ensue. These symptoms are mentioned above, and when they become prominent in the body, a state called pralaya (devastation) is manifest.
(Sri Caitanya Caritamrta-----2:3:162-----purport).

Apart from this, Kṛṣṇa can eat the food with any one of His transcendental senses. He can eat by seeing the food or by touching it. Nor should one think that it is necessary for Kṛṣṇa to eat. He does not become hungry like an ordinary human being; nonetheless, He presents Himself as being hungry, and as such, He can eat everything and anything, regardless of quantity. The philosophy underlying Kṛṣṇa's eating is understandable by our transcendental senses. When our senses are purified by constantly being engaged in the devotional service of the Lord, we can understand Kṛṣṇa's activities, names, forms, qualities, pastimes and entourage.
ataḥ śrī-kṛṣṇa-nāmādi na bhaved grāhyam indriyaiḥ
sevonmukhe hi jihvādau svayam eva sphuraty adaḥ
(CC.2:17:136)
"No one can understand Kṛṣṇa by the blunt material senses. But He reveals Himself to the devotees, being pleased with them for their transcendental loving service unto Him." (Bhakti-rasāmṛta-sindhu 1.2.234) The devotees understand Kṛṣṇa through revelation. It is not possible for a mundane scholar to understand Kṛṣṇa and His pastimes through research work on the nondevotional platform.

(Sri Caitanya Caritamrta-----2:4:77-----purport).

In the Bhakti-rasāmṛta-sindhu, jāḍya is explained as loss of memory brought about by severe shock due to separation from the beloved. In that state of mind, one loses all concern for loss and gain, hearing and seeing, as well as all other considerations. This marks the preliminary appearance of illusion.

(Sri Caitanya Caritamrta-----2:4:202-----purport).

The word sūddīpta-sāttvika is explained as follows by Śrīla Bhaktisiddhānta Sarasvatī Ṭhākura: "The Bhakti-rasāmṛta-sindhu mentions eight kinds of transcendental transformations in the bodies of advanced devotees. These are sometimes checked by the devotee, and there are two stages of such checking, technically known as dhūmāyitā and jvalitā. The dhūmāyitā (smoking) stage is exhibited when only one or two transformations are slightly present and it is possible to conceal them. When more than two or three transcendental transformations are manifest and it is still possible to conceal them, although with great difficulty, that stage is called jvalitā (lighted). When four or five symptoms are exhibited, the dīpta (blazing) stage has been reached. When five, six or all eight symptoms are simultaneously manifest, that position is called uddīpta (inflamed). And when all eight symptoms are multiplied a thousand times and are all visible at once, the devotee is in the sūddīpta (intensely inflamed) stage. Nitya-siddha-bhakta indicates the eternally liberated associates of the Lord. Such devotees enjoy the company of the Lord in four relationships—as servant, friend, parent or conjugal lover."

(Sri Caitanya Caritamrta-----2:6:12-----purport).

Tat tvam asi is a warning to the living entity not to mistake the body for the self. Therefore tat tvam asi is especially meant for the conditioned soul. The chanting of oṁkāra or the Hare Kṛṣṇa mantra is meant for the liberated soul. Śrīla Rūpa Gosvāmī has said, ayi mukta-kulair upāsyamānam (Nāmāṣṭaka 1). Thus the holy name of the Lord is chanted by the liberated souls. Similarly, Parīkṣit Mahārāja says, nivṛtta-tarṣair upagīyamānāt (S.B.10:1:4). The holy name of the Lord can be chanted by those who have fully satisfied their material desires or who are fully situated on the transcendental platform and devoid of material desire. The name of the Lord can be chanted by one who is completely freed from material contamination (anyābhilāṣitā-śūnyaṁ jñāna-karmādy-anāvṛtam (Bhakti-rasāmṛta-sindhu 1.1.11)). Śaṅkarācārya has indirectly minimized the value of the principal Vedic mantra (oṁkāra) by accepting a subordinate vibration (tat tvam asi) as the most important Vedic mantra.
