Prabhupāda: So each king had different colored horses and differently marked flag on the top of the chariot. Just like Arjuna's chariot was drawn by white horses. Śveta. Śveta means white. And his grandson, his horses are of blackish. Not... Śyāma is not black. Blackish. Swarthy. No, blackish. Turaṅga, jeweled. They have four horses in chariot, and there is a charioteer and flag marked with lion. This lion is not to be considered an ordinary lion. This lion is Mṛgendra or Narahari, Nṛsiṁha-deva. Arjuna's chariot was with flag marked with Vajrāṅga, Hanumānjī, Hanumānjī. Kṛṣṇa's chariot flag is marked with Garuḍa. So these are the distinctive marks. One will understand immediately, "This is such and such king's chariot." That mark is there.
So Arjuna kept upon him Vajrāṅgajī, Hanumān, because he considered Hanumān his guru. Hanumān was servant of Lord Rāmacandra. He fought the battlefield of Laṅkā between Rāma and Rāvaṇa. He could not use any weapon, but he was very strong. He knew how to throw stones. In this way, he fought in the battle and won over the Rāvaṇa. Rāvaṇa was killed by Lord Rāmacandra. So Vaiṣṇava does not mean he cannot do anything else except chanting. That is, of course, the supreme objective, śravaṇaṁ kīrtanaṁ viṣṇoḥ (SB 7.5.23), to hear about Viṣṇu and chant about Kṛṣṇa. That is very experienced life, experienced Vaiṣṇava. He can concentrate chanting. Just like Haridāsa Ṭhākura. Haridāsa Ṭhākura was chanting. But Śrī Caitanya Mahāprabhu Himself, Nityānanda Prabhu, they were preaching.
