In the Padyāvalī of Rūpa Gosvāmī it is stated that when the gopīs hear the sound of Kṛṣṇa's flute, they immediately forget all rebukes offered by the elderly members of their families, their defamation and the harsh behavior of their husbands. Their only thought is to go out in search of Kṛṣṇa. When the gopīs meet Kṛṣṇa, the display of their exchanging glances as well as their joking and laughing behavior is called anubhāva, or sub-ecstasy in conjugal love.
In the Lalita-mādhava, Rūpa Gosvāmī explains that the movements of Kṛṣṇa's eyebrows are just like the Yamunā, and the smiling of Rādhārāṇī is just like the moonshine. When the Yamunā and the moonshine come in contact on the bank of the river, the water tastes just like nectar, and drinking it gives great satisfaction. It is as cooling as piles of snow. Similarly, in the Padyāvalī, one constant companion of Rādhārāṇī says, "My dear moon-faced Rādhārāṇī, Your whole body appears to be very content, yet there are signs of tears in Your eyes. Your speech is faltering, and Your chest is also heaving. By all these signs I can understand that You must have heard the blowing of Kṛṣṇa's flute, and, as a result of this, Your heart is now melting."
In the same Padyāvalī there is the following description, which is taken as a sign of frustration in conjugal love. Śrīmatī Rādhārāṇī said, "Dear Mr. Cupid, please do not excite Me by throwing your arrows at My body. Dear Mr. Air, please do not arouse Me with the fragrance of flowers. I am now bereft of Kṛṣṇa's loving attitude, so under the circumstances, what is the use of My sustaining this useless body? There is no need for such a body by any living entity." This is a sign of frustration in ecstatic love for Kṛṣṇa.
Similarly, in Dāna-keli-kaumudī, Śrīmatī Rādhārāṇī, pointing to Kṛṣṇa, says, "This clever boy of the forest has the beauty of a bluish lotus flower, and He can attract all the young girls of the universe. Now after giving Me a taste of His transcendental body, He has enthused Me, and it is more than I can tolerate. I am now feeling like a female elephant who has been enthused by a male elephant!" This is an instance of jubilation in ecstatic love with Kṛṣṇa.
Steady ecstasy of conjugal love is the original cause of bodily enjoyment. In the Padyāvalī this original cause of union is described when Rādhārāṇī tells one of Her constant companions: "My dear friend, who is this boy whose eyelids, dancing constantly, have increased the beauty of His face and attracted My desire for conjugal love? His ears are decorated with the buds of aśoka flowers, and He has dressed Himself in yellow robes. By the sound of His flute, this boy has already made Me impatient."
The conjugal love of Rādhā-Kṛṣṇa is never disturbed by any personal consideration. The undisturbed nature of the conjugal love between Rādhā and Kṛṣṇa is described thus: "Just a little distance away from Kṛṣṇa was Mother Yaśodā, and Kṛṣṇa was surrounded by all of His friends. In front of His eyes there was Candrāvalī, and, at the same time, on a chunk of stone in front of the entrance to Braja, there was standing the demon known as Vṛṣāsura. But even in such circumstances, when Kṛṣṇa saw Rādhārāṇī standing just behind a bush of many creepers, immediately His beautiful eyebrows moved just like lightning towards Her."
Another instance is described as follows: "On one side of the courtyard the dead body of Śaṅkhāsura was lying, surrounded by many jackals. On another side were many learned brāhmaṇas who were all self-controlled. They were offering nice prayers, which were as soothing as the cool breeze in summer. In front of Kṛṣṇa, Lord Baladeva was standing, causing a cooling effect. But even amidst all these different circumstances of soothing and disturbing effects, the lotus flower of ecstatic conjugal love that Kṛṣṇa felt for Rādhārāṇī could not wither." This love of Kṛṣṇa for Rādhārāṇī is often compared to a blooming lotus: the only difference is that Kṛṣṇa's love remains ever-increasingly beautiful.
Conjugal love is divided into two portions: vipralambha, or conjugal love in separation, and sambhoga, or conjugal love in direct contact. Vipralambha, separation, has three sub-divisions known as 1) pūrva-rāga, or preliminary attraction, 2) māna, or seeming anger, and 3) pravāsa, or separation by distance.
When the lover and the beloved have a distinct feeling of not meeting each other, that stage is called pūrva-rāga, or preliminary attraction. In Padyāvalī Rādhārāṇī told Her companion, "My dear friend, I was just going to the bank of the Yamunā, and all of a sudden a very nice boy whose complexion is like a dark blue cloud became visible in front of My eyes. He glanced over Me in a way that I cannot describe. But since this has occured, I am sorry that I can no longer engage My mind in the duties of My household affairs." This is an instance of preliminary attraction for Kṛṣṇa. In Śrīmad-Bhāgavatam, Tenth Canto, 53rd Chapter, verse 2, Kṛṣṇa told the messenger brāhmaṇa who came from Rukmiṇī: "My dear brāhmaṇa, just like Rukmiṇī I cannot sleep at night, and My mind is always fixed on her. I know that her brother Rukmī is against Me, and due to his persuasion, My marriage with her has been cancelled." This is another instance of preliminary attraction.
As far as māna, or anger, is concerned, there is the following incident described in Gīta-govinda: "When Śrīmatī Rādhārāṇī saw Kṛṣṇa enjoying Himself in the company of several other gopīs, She became a little jealous because Her special prestige was being dimmed. Therefore, She immediately left the scene and took shelter in a nice flower bush where the black drones were humming. Then, hiding Herself behind the creepers, She began to express Her sorrow to one of Her consorts." This is an instance of a seeming disagreement.
An example of pravāsa, or being out of contact because of living in a distant place, is given in the Padyāvalī as follows: "Since the auspicious day when Kṛṣṇa left for Mathurā, Śrīmatī Rādhārāṇī has been pressing Her head on one of Her hands and constantly shedding tears. Her face is always wet now, and therefore there is no chance of Her sleeping even for a moment." When the face becomes wet, the sleeping tendency is immediately removed. So when Rādhārāṇī was always weeping for Kṛṣṇa because of His separation, there was no chance of Her getting any sleep for Herself. In the Prahlāda-saṁhitā Uddhava says, "The Supreme Personality of Godhead, Govinda, painstricken due to being pierced by the arrows of Cupid, is always thinking of you (the gopīs), and He is not even accepting His regular lunch. Nor is He getting any proper rest.
