vṛṣa hañā - becoming a bull; kṛṣṇa-sane - with Kṛṣṇa; māthā-māthi raṇa - fighting head to head; kabhu - sometimes; kṛṣṇa - Kṛṣṇa; kare - does; tāṅra - His; pāda-saṁvāhana - massaging the feet.

Playing like a bull, Lord Balarāma fights with Kṛṣṇa head to head. And sometimes Lord Kṛṣṇa massages the feet of Lord Balarāma.
