vraje gopa-bhāva rāmera, pure kṣatriya-bhāvana varṇa-veśa-bheda, tāte ‘vilāsa’ tāṅra nāma
“Balarāma, who has the same original form as Kṛṣṇa, is Himself a cowherd boy in Vṛndāvana, and He also considers Himself a member of the kṣatriya race in Dvārakā. Thus His color and dress are different, and He is called a pastime form of Kṛṣṇa.
