SB Canto 4

There is the viśralambha-sakhya, the higher fraternal worship of the Lord especially enjoyed by the cowherd boys. Although there is friendship between Kṛṣṇa and the cowherd boys, this friendship is different from the aiśvarya friendship between Kṛṣṇa and Arjuna.

SB 4.24.45-46, Purport:

The inhabitants of Vṛndāvana—the gopīs, mother Yaśodā, Nanda Mahārāja, the cowherd boys, the cows and everyone else—are actually on the rāga-mārga or bhāgavata-mārga platform. They participate in five basic rasas-dāsya, sakhya, vātsalya, mādhurya and śānta. But although these five rasas are found in the bhāgavata-mārga, the bhāgavata-mārga is especially meant for vātsalya and mādhurya, or paternal and conjugal relationships. Yet there is the viśralambha-sakhya, the higher fraternal worship of the Lord especially enjoyed by the cowherd boys. Although there is friendship between Kṛṣṇa and the cowherd boys, this friendship is different from the aiśvarya friendship between Kṛṣṇa and Arjuna. When Arjuna saw the viśva-rūpa, the gigantic universal form of the Lord, he was afraid for having treated Kṛṣṇa as an ordinary friend; therefore he begged Kṛṣṇa's pardon. However, the cowherd boys who are friends of Kṛṣṇa in Vṛndāvana sometimes ride on the shoulders of Kṛṣṇa. They treat Kṛṣṇa equally, just as they treat one another, and they are never afraid of Him, nor do they ever beg His pardon. Thus the rāga-mārga, or bhāgavata-mārga, friendship exists on a higher platform with Kṛṣṇa, namely the platform of vipralambha friendship. Paternal friendship, paternal service and conjugal service are visible in the Vṛndāvana rāga-mārga relationships.
