"May the pastimes of Śrī Kṛṣṇa reduce the miseries existing in the material world and nullify all unwanted desires. The pastimes of the Supreme Personality of Godhead are like śikhariṇī, a blend of yogurt and sugar candy. They overpower the pride of even the nectar produced on the moon, for they distribute the sweet fragrance of the concentrated loving affairs of Śrīmatī Rādhārāṇī and the gopīs."
(Sri Caitanya Caritamrta----3;1:128----translation).

“(Experiencing previous attachment to Kṛṣṇa (pūrva-rāga), Śrīmatī Rādhārāṇī thought:) "Since I have heard the name of a person called Kṛṣṇa, I have practically lost My good sense. Then, there is another person who plays His flute in such a way that after I hear the vibration, intense madness arises in My heart. And again there is still another person to whom My mind becomes attached when I see His beautiful lightninglike effulgence in His picture. Therefore I think that I am greatly condemned, for I have become simultaneously attached to three persons. It would be better for Me to die because of this."
(Sri Caitanya Caritamrta----3:1:128----translation).

"The beauty of Śrīmatī Rādhārāṇī"s eyes forcibly devours the beauty of newly grown blue lotus flowers, and the beauty of Her face surpasses that of an entire forest of fully blossomed lotuses. Her bodily luster seems to place even gold into a painful situation. Thus the wonderful, unprecedented beauty of Śrīmatī Rādhārāṇī is awakening in Vṛndāvana.’
(Sri Caitanya Caritamrta----3:1:169----translation).

"Although the effulgence of the moon is brilliant initially at night, in the daytime it fades away. Similarly, although the lotus is beautiful during the daytime, at night it closes. But, O My friend, the face of My most dear Śrīmatī Rādhārāṇī is always bright and beautiful, both day and night. Therefore, to what can Her face be compared?"
(Sri Caitanya Caritamrta----3:1:170----translation).

I offer my respectful obeisances unto the lotus feet of my spiritual master and of all the other preceptors on the path of devotional service. I offer my respectful obeisances unto all the Vaiṣṇavas and unto the six Gosvāmīs, including Śrīla Rūpa Gosvāmī, Śrīla Sanātana Gosvāmī, Raghunātha dāsa Gosvāmī, Jīva Gosvāmī and their associates. I offer my respectful obeisances unto Śrī Advaita Ācārya Prabhu, Śrī Nityānanda Prabhu, Śrī Caitanya Mahāprabhu, and all His devotees, headed by Śrīvāsa Ṭhākura. I then offer my respectful obeisances unto the lotus feet of Lord Kṛṣṇa, Śrīmatī Rādhārāṇī and all the gopīs, headed by Lalitā and Viśākhā.
(Sri Caitanya Caritamrta----3:2:1----translation).

The unalloyed love of the gopīs and Śrīmatī Rādhārāṇī is without any trace of material lust. The criterion of such transcendental love is that its only purpose is to satisfy Kṛṣṇa.
(Sri Caitanya Caritamrta----3:7:39----translation).

The gopīs were dancing in a circle, and in the middle of that circle, Kṛṣṇa, the son of Mahārāja Nanda, danced with Rādhārāṇī.
(Sri Caitanya Caritamrta----3:14:19----translation).

These are the feelings of Śrīmatī Rādhārāṇī. First Lord Caitanya felt that He had been taken to Vṛndāvana, where He saw Kṛṣṇa's rāsa dance with the gopīs. Then He was brought to Kurukṣetra to see Lord Jagannātha, His sister (Subhadrā) and Lord Balarāma. Śrī Caitanya Mahāprabhu lost Vṛndāvana and Kṛṣṇa, the master of Vṛndāvana. At this time, Caitanya Mahāprabhu experienced divyonmāda, transcendental madness in separation from Kṛṣṇa. At Kurukṣetra, Kṛṣṇa displays His opulence, whereas in Vṛndāvana He is in His original position. Kṛṣṇa never goes even a step away from Vṛndāvana; therefore Kurukṣetra is less important for the gopīs than Vṛndāvana.
(Sri Caitanya Caritamrta----3:14:37----purport).

Although devotees who worship Kṛṣṇa in opulence (His Vaikuṇṭha aspect) may prefer to see Lord Kṛṣṇa at Kurukṣetra along with Subhadrā and Balarāma, the gopīs want to see Kṛṣṇa in Vṛndāvana, performing the rāsa dance with Śrīmatī Rādhārāṇī. Śrī Caitanya Mahāprabhu showed by practical example how one can cultivate the mood ofRādhārāṇī and the other gopīs in separation from Kṛṣṇa. Devotees absorbed in this mood do not like to see Kṛṣṇa anywhere else but Vṛndāvana. Therefore Śrī Caitanya Mahāprabhu lamented, "I found Kṛṣṇa in Vṛndāvana, and now I have again lost Him and come to Kurukṣetra."
(Sri Caitanya Caritamrta----3:14:37----purport).

"The ten bodily transformations resulting from separation from Kṛṣṇa are anxiety, wakefulness, mental agitation, thinness, uncleanliness, talking like a madman, disease, madness, illusion and death."
This verse is part of a description of Śrīmatī Rādhārāṇī’s different traits from Ujjvala-nīlamaṇi (Vipralambha-prakaraṇa 153), by Śrīla Rūpa Gosvāmī. In this book, he elaborately explains the ten symptoms as follows.
Cintā, anxiety. As stated in the Haṁsa-dūta (2):
yadā yāto gopī-hṛdaya-madano nanda-sadanān
mukundo gāndinyās tanayam anurundhan madhu-purīm
tadāmāṅkṣīc cintā-sariti ghana-ghūrṇāparicayair
agādhāyāṁ bādhāmaya-payasi rādhā virahiṇī
"At Akrūra's request, Kṛṣṇa and Balarāma left the house of Nanda Mahārāja for Mathurā. At that time the mind of Śrīmatī Rādhārāṇī was disrupted, and She became almost mad because of extreme separation from Kṛṣṇa. She experienced great mental pain and agitation, which caused Her to drown in mental speculation in the river of anxiety. She thought, "Now I am going to die, and when I die, Kṛṣṇa will surely come back to see Me again. But when He hears of My death from the people of Vṛndāvana, He will certainly be very unhappy. Therefore I shall not die."" This is the explanation of the word cintā.
(Sri Caitanya Caritamrta----3:14:53---- translation and purport).

Thinking Herself very unfortunate, Śrīmatī Rādhārāṇī addressed Her very dear friend Viśākhā, "My dear friend, if I could see Kṛṣṇa in My dreams, I would certainly be glorified for My great fortune. But what can I do? Sleep also plays mischievously with Me. Indeed, it has become My enemy. Therefore I have not slept since the departure of Kṛṣṇa."
Udvega, mental agitation. This word is explained in the Haṁsa-dūta (104) as follows:
mano me hā kaṣṭaṁ jvalati kim ahaṁ hanta karavai
na pāraṁ nāvāraṁ su-mukhi kalayāmy asya jaladheḥ
iyaṁ vande mūrdhnā sapadi tam upāyaṁ kathaya me
parāmṛśye yasmād dhṛti-kaṇikayāpi kṣaṇikayā
Śrīmatī Rādhārāṇī addressed Lalitā, "My dear beautiful-faced Lalitā, I cannot express how My heart is burning. It is a great, unfathomable ocean of anxiety. Still, I wish to offer My obeisances at your lotus feet. What shall I do? Please consider My condition and advise Me how I can become peaceful. That is My desire."
(Sri Caitanya Caritamrta----3:14:53---- purport).

Tānava, thinness, is described as follows:
udañcad-vaktrāmbhoruha-vikṛtir antaḥ-kulaṣitā
sadāhārābhāva-glapita-kuca-kokā yadu-pate
viśuṣyantī rādhā tava viraha-tāpād anu-dinaṁ
nidāghe kuly eva kraśima-paripākaṁ prathayati
When Uddhava returned to Mathurā after visiting Vṛndāvana, Lord Kṛṣṇa inquired from him about Rādhārāṇī and Viśākhā. Uddhava replied as follows: "Consider the condition of the gopīs! Śrīmatī Rādhārāṇī especially is in a very painful condition because of separation from You. She has grown skinny, and Her bodily luster is almost gone. Her heart is immersed in pain, and because She has given up eating, Her breasts have become black, as if diseased. Because of separation from You, all the gopīs, especially Rādhārāṇī, appear like dried-up water holes under the scorching heat of the sun."
(Sri Caitanya Caritamrta----3:14:53---- purport).

Pralāpa, mad talking, is explained in the Lalita-mādhava as follows:
kva nanda-kula-candramāḥ kva śikhi-candra-kālaṅkṛtiḥ
kva mandra-muralī-ravaḥ kva nu surendra-nīla-dyutiḥ
kva rāsa-rasa-tāṇḍavī kva sakhi jīva-rakṣauṣadhir
nidhir mama suhṛttamaḥ kva tava hanta hā dhig vidhiḥ
This is Śrīmatī Rādhārāṇī’s lamentation for Her beloved Kṛṣṇa, who was away from home. A woman whose husband has left home and gone to a foreign land is called proṣita-bhartṛkā. Lamenting for Kṛṣṇa in the same way that such a woman laments for her husband, Śrīmatī Rādhārāṇī said, "My dear friend, where is the glory of the family of Mahārāja Nanda, who wears a half-moon ornament on His head? Where is Kṛṣṇa, whose hue is like that of the indranīla jewel and who plays so nicely on His flute? Where is your friend, the best of all men, so expert in dancing in the circle of the rāsa dance? Where is He who is the real medicine to save Me from dying of heart disease? I must condemn Providence, for he has caused Me so many tribulations by separating Me from Kṛṣṇa."
(Sri Caitanya Caritamrta----3:14:53---- purport).

Caitanya Mahāprabhu informs us that in every country and in every scripture there is some hint of love of Godhead. But no one knows what love of Godhead actually is. The Vedic scriptures, however, are different in that they can direct the individual in the proper way to love God. Other scriptures do not give information on how one can love God, nor do they actually define or describe what or who the Godhead actually is. Although they officially promote love of Godhead, they have no idea how to execute it. But Caitanya Mahāprabhu gives a practical demonstration of how to love God in a conjugal relationship. Taking the part of Śrīmatī Rādhārāṇī, Caitanya Mahāprabhu tried to love Kṛṣṇa as Rādhārāṇī loved Him. Kṛṣṇa was always amazed by Rādhārāṇīs love. "How does Rādhārāṇī give Me such pleasure?" He would ask. In order to study Rādhārāṇī, Kṛṣṇa lived in Her role and tried to understand Himself. This is the secret of Lord Caitanya's incarnation. Caitanya Mahāprabhu is Kṛṣṇa, but He has taken the mood and role of Rādhārāṇī to show us how to love Kṛṣṇa. Thus the author writes in the fifth verse, "I offer my respectful obeisances unto the Supreme Lord, who is absorbed in Rādhārāṇīs thoughts."
(Teachings of Lord Caitanya).

This brings up the question of who Śrīmatī Rādhārāṇī is and what Rādhā-Kṛṣṇa is. Actually Rādhā-Kṛṣṇa is the exchange of love—but not ordinary love. Kṛṣṇa has immense potencies, of which three are principal: the internal, the external and the marginal potencies. In the internal potency there are three divisions: samvit, hlādinīand sandhinī. The hlādinīpotency is Kṛṣṇa's pleasure potency. All living entities have this pleasure-seeking potency, for all beings are trying to have pleasure. This is the very nature of the living entity. At present we are trying to enjoy our pleasure potency by means of the body in the material condition. By bodily contact we are attempting to derive pleasure from material sense objects. But we should not entertain the nonsensical idea that Kṛṣṇa, who is always spiritual, also tries to seek pleasure on this material plane. In the Bhagavad-gītāKṛṣṇa describes the material universe as a nonpermanent place full of miseries. Why, then, would He seek pleasure in matter? He is the Supersoul, the supreme spirit, and His pleasure is beyond the material conception.
(Teachings of Lord Caitanya).

To learn how Kṛṣṇa enjoys pleasure, we must study the first nine cantos of Śrīmad-Bhāgavatam, and then we should study the Tenth Canto, in which Kṛṣṇa's pleasure potency is displayed in His pastimes with Rādhārāṇī and the damsels of Vraja. Unfortunately, unintelligent people turn at once to the sports of Kṛṣṇa in the Daśama-skandha, the Tenth Canto. Kṛṣṇa's embracing Rādhārāṇī or His dancing with the cowherd girls in the rāsa dance are generally not understood by ordinary men, because they consider these pastimes in the light of mundane lust. They foolishly think that Kṛṣṇa is like themselves and that He embraces the gopīs just as an ordinary man embraces a young girl. Some people thus become interested in Kṛṣṇa because they think that His religion allows indulgence in sex. This is not kṛṣṇa-bhakti, love of Kṛṣṇa, but prākṛta-sahajiyā—materialistic lust.
(Teachings of Lord Caitanya).

To avoid such errors, we should understand what Rādhā-Kṛṣṇa actually is. Rādhā and Kṛṣṇa display Their pastimes through Kṛṣṇa's internal energy. The pleasure potency of Kṛṣṇa's internal energy is a most difficult subject matter, and unless one understands what Kṛṣṇa is, one cannot understand it. Kṛṣṇa does not take any pleasure in this material world, but He has a pleasure potency. Because we are part and parcel of Kṛṣṇa, the pleasure potency is within us also, but we are trying to exhibit that pleasure potency in matter. Kṛṣṇa, however, does not make such a vain attempt. The object of Kṛṣṇa's pleasure potency is Rādhārāṇī; Kṛṣṇa exhibits His potency as Rādhārāṇī and then engages in loving affairs with Her. In other words, Kṛṣṇa does not take pleasure in this external energy but exhibits His internal energy, His pleasure potency, as Rādhārāṇī and then enjoys with Her. Thus Kṛṣṇa manifests Himself as Rādhārāṇī in order to enjoy His internal pleasure potency. Of the many extensions, expansions and incarnations of the Lord, this pleasure potency is the foremost and chief.
(Teachings of Lord Caitanya).

It is not that Rādhārāṇī is separate from Kṛṣṇa. Rādhārāṇī is also Kṛṣṇa, for there is no difference between the energy and the energetic. Without energy, there is no meaning to the energetic, and without the energetic, there is no energy. Similarly, without Rādhā there is no meaning to Kṛṣṇa, and without Kṛṣṇa there is no meaning to Rādhā. Because of this, the Vaiṣṇava philosophy first of all pays obeisances to and worships the internal pleasure potency of the Supreme Lord. Thus the Lord and His potency are always referred to as Rādhā-Kṛṣṇa. Similarly, those who worship Nārāyaṇa first of all utter the name of Lakṣmī, as Lakṣmī-Nārāyaṇa. Similarly, those who worship Lord Rāma first of all utter the name of Sītā. In any case—Sītā-Rāma, Rādhā-Kṛṣṇa, Lakṣmī-Nārāyaṇa—the potency always comes first.
(Teachings of Lord Caitanya).

Rādhā and Kṛṣṇa are one, and when Kṛṣṇa desires to enjoy pleasure, He manifests Himself as Rādhārāṇī. The spiritual exchange of love between Rādhā and Kṛṣṇa is the actual display of Kṛṣṇa's internal pleasure potency. Although we speak of "when" Kṛṣṇa desires, just when He did desire we cannot say. We only speak in this way because in conditioned life we take it that everything has a beginning; however, in spiritual life everything is absolute, and so there is neither beginning nor end. Yet in order to understand that Rādhā and Kṛṣṇa are one and that They also become divided, the question "When?" automatically comes to mind. When Kṛṣṇa desired to enjoy His pleasure potency, He manifested Himself in the separate form of Rādhārāṇī, and when He wanted to understand Himself through the agency of Rādhā, He united with Rādhārāṇī, and that unification is called Lord Caitanya. This is all explained by Śrīla Kṛṣṇadāsa Kavirāja in the fifth verse of the Caitanya-caritāmṛta.
(Teachings of Lord Caitanya).

In the next verse the author further explains why Kṛṣṇa assumed the form of Caitanya Mahāprabhu. Kṛṣṇa desired to know the glory of Rādhās love. "Why is She so much in love with Me?" Kṛṣṇa asked. "What is My special qualification that attracts Her so? And what is the actual way in which She loves Me?" It seems strange that Kṛṣṇa, as the Supreme, should be attracted by anyone's love. A man searches after the love of a woman because he is imperfect—he lacks something. The love of a woman, that potency and pleasure, is absent in man, and therefore a man wants a woman. But this is not the case with Kṛṣṇa, who is full in Himself. Thus Kṛṣṇa expressed surprise: "Why am I attracted by Rādhārāṇī? And when Rādhārāṇī feels My love, what is She actually feeling?" To taste the essence of that loving exchange, Kṛṣṇa made His appearance in the same way that the moon appears on the horizon of the sea. Just as the moon was produced by the churning of the sea, by the churning of spiritual loving affairs the moon of Caitanya Mahāprabhu appeared. Indeed, Lord Caitanya's complexion was golden, just like the luster of the moon. Although this is figurative language, it conveys the meaning behind the appearance of Caitanya Mahāprabhu.
(Teachings of Lord Caitanya).

Regarding the gopīs' dealings with Śrī Kṛṣṇa in Vṛndāvana, Śrīmad-Bhāgavatam 10.30.36–38 describes how when Śrī Kṛṣṇa took Śrīmatī Rādhikā alone from the rāsa dance, She proudly thought, "My dear Lord Kṛṣṇa has left the other gopīs, although they are as beautiful as I am, and He is satisfied with Me alone." In the forest She told Kṛṣṇa, "My dear Kṛṣṇa, I am unable to move anymore. Now if You like You can take Me wherever You desire." Kṛṣṇa replied, "You can climb on My shoulder," but as soon as He said this He disappeared, whereupon ŚrīmatīRādhikā repented very much.
(Teachings of Lord Caitanya).

In His two-handed form as the cowherd son of Nanda Mahārāja, Kṛṣṇa fully exhibits His opulence, beauty, wealth, attractiveness and pastimes. Indeed, in some Vaiṣṇava literature it is found that sometimes, in His form as Vāsudeva, He becomes attracted to His form of Govinda in Vṛndāvana. Thus as Vāsudeva He sometimes desires to enjoy as Govinda does, although the Govinda form and the Vāsudeva form are ultimately one and the same. In this regard, there is a passage in the Lalita-mādhava (4.19), in which Kṛṣṇa addresses Uddhava as follows: "My dear friend, the form of this cowherd boy Govinda attracts Me. Indeed, I wish to be like the damsels of Vraja, who are also attracted by this form of Govinda." Similarly, later in the Lalita-mādhava (8.34), Kṛṣṇa says: "Oh, how wonderful it is! Who is this person? After seeing Him, I am so much attracted that I now desire to embrace Him just like Rādhikā."
(Teachings of Lord Caitanya).

The supreme lover is Kṛṣṇa in Vṛndāvana, and the supreme beloved is Rādhārāṇī. Kṛṣṇa has sixty-four main qualities, and His devotee takes transcendental pleasure in hearing of them. As explained in the Bhakti-rasāmṛta-sindhu, the characteristics are as follows: (1) His body is well constructed; (2) His body is full of auspicious symptoms; (3) His body is beautiful; (4) He is very glorious; (5) He is very strong; (6) He always looks like a boy of sixteen; (7) He is well versed in various languages; (8) He is truthful; (9) He is decorated with pleasing words; (10) He is expert in speaking.
(Teachings of Lord Caitanya).

Thus Kṛṣṇa has sixty-four transcendental qualities. Śrīmatī Rādhārāṇī has twenty-five transcendental qualities, with which She can control even Kṛṣṇa. Her transcendental qualities are as follows: (1) She is sweetness personified; (2) She is a fresh young girl; (3) Her eyes are always moving; (4) She is always brightly smiling; (5) She possesses all auspicious marks on Her body; (6) She can agitate Kṛṣṇa by the aroma of Her person; (7) She is expert in the art of singing; (8) She speaks very nicely and sweetly; (9) She is expert in presenting feminine attractions; (10) She is modest and gentle; (11) She is always very merciful; (12) She is transcendentally cunning; (13) She knows how to dress nicely; (14) She is always shy; (15) She is always respectful; (16) She is always patient; (17) She is very grave; (18) She is enjoyed by Kṛṣṇa; (19) She is always situated on the highest devotional platform; (20) She is the abode of love of the residents of Gokula; (21) She can give shelter to all kinds of devotees; (22) She is always affectionate to superiors and inferiors; (23) She is always obliged by the dealings of Her associates, (24) She is the greatest among Kṛṣṇa's girlfriends; (25) She always keeps Kṛṣṇa under Her control.
(Teachings of Lord Caitanya).

Thus Kṛṣṇa and Rādhārāṇī are both transcendentally qualified, and They attract one another. But Rādhārāṇīs transcendental attractiveness is greater than Kṛṣṇa's, for Her attractiveness is the transcendental taste in conjugal love. Similarly, there are transcendental tastes in servitorship, friendship and other relationships with Kṛṣṇa. These can be described with reference to the context of the Bhakti-rasāmṛta-sindhu.
(Teachings of Lord Caitanya).

The Lord has innumerable incarnations, and oṁkāra is one of them, in the form of a transcendental syllable. As Kṛṣṇa states in the Bhagavad-gītā (9.17): "Among vibrations, I am the syllable om." This means that oṁkāra is nondifferent from Kṛṣṇa. Impersonalists, however, give more importance to oṁkāra than to the Personality of Godhead, Kṛṣṇa. But the fact is that any representational incarnation of the Supreme Lord is nondifferent from Him. Such an incarnation or representation is as good spiritually as the Supreme Lord. Oṁkāra is therefore the ultimate representation of all the Vedas. Indeed, the Vedic mantras or hymns have transcendental value because they are prefixed by the syllable om. The Vaiṣṇavas interpret oṁkāra, a combination of the letters a, u and m, as follows: By the letter a, Kṛṣṇa, the Supreme Personality of Godhead, is indicated; by the letter u, Kṛṣṇa's eternal consort, Śrīmatī Rādhārāṇī, is indicated; and by the letter m, the living entity, the eternal servitor of the Supreme Lord, is indicated. Śaṅkara has not given such importance to oṁkāra. But such importance is given in the Vedas, the Rāmāyaṇa, the Purāṇas and the Mahābhārata, from beginning to end. Thus the glories of the Supreme Lord, the Supreme Personality of Godhead, are declared.
