Sometimes there were also signs of death caused by separation from Kṛṣṇa. Once Kṛṣṇa was told: "My dear enemy of Kaṁsa, because of their separation from You, the cowherd boys are suffering too much, and they are now lying down in the valleys, breathing only slightly. In order to sympathize with the boys' regrettable condition, even the forest friends, the deer, are shedding tears."
In the Mathurā-khaṇḍa chapter of the Skanda Purāṇa, there is a description of Kṛṣṇa and Balarāma, surrounded by all the cowherd boys, always engaged in taking care of the cows and calves. When Kṛṣṇa was met by Arjuna at a potter's shop in the city of Drupadanagara, because of the similarity of their bodily features they made intimate friendship. This is an instance of friendship caused by the attraction of similar bodies.
In the Tenth Canto of Śrīmad-Bhāgavatam, 71st Chapter, 25th verse, it is stated that when Kṛṣṇa arrived in the city of Indraprastha, Bhīma was so overwhelmed with joy that, with tears in his eyes and a smiling face, he immediately embraced his maternal cousin. Following him were his young brothers Nakula and Sahadeva, along with Arjuna, and they all became so overwhelmed at seeing Kṛṣṇa that with full satisfaction they embraced the Lord, who is known as Acyuta (the infallible). There is a similar statement about the cowherd boys of Vṛndāvana. When Kṛṣṇa was on the battlefield of Kurukṣetra, all the cowherd boys came to see Him, wearing jeweled earrings in their ears. Becoming so greatly overjoyed, they extended their arms and embraced Kṛṣṇa as their old friend. These are instances of full satisfaction in friendship with Kṛṣṇa.
In the Tenth Canto, 12th Chapter, 11th verse of Śrīmad-Bhāgavatam it is stated that even after undergoing severe penances and austerities and performing the yogic principles, the great mystic yogīs can hardly become eligible to achieve the dust of the lotus feet of Kṛṣṇa, but the same Personality of Godhead, Kṛṣṇa, is easily available to the vision of the residents of Vṛndāvana. This means there is no comparison to these devotees' great fortune. The friendly relationship of the cowherd boys with Kṛṣṇa is a particular type of spiritual ecstasy almost similar to the ecstasy of conjugal love. It is very difficult to explain this ecstasy of loving affairs between the cowherd boys and Kṛṣṇa. Great expert devotees like Rūpa Gosvāmī and others express their astonishment at the inconceivable feelings which are in Kṛṣṇa and His cowherd boy friends.
This particular type of ecstatic love shared between Kṛṣṇa and His confidential friends further develops into parental love, and on from there it may develop into conjugal love, the most exalted humor or mellow of ecstatic love between Lord Kṛṣṇa and His devotees.
