There is a nice example of the friendship between Kṛṣṇa and Arjuna on the Battlefield of Kurukṣetra. When the fighting was going on, Aśvatthāmā, the son of Droṇācārya, unceremoniously attacked Kṛṣṇa, although according to the prevailing rules of chivalry one’s chariot driver should never be attacked by the enemy. Aśvatthāmā behaved heinously in so many ways that he did not hesitate to attack Kṛṣṇa’s body, although Kṛṣṇa was acting only as charioteer for Arjuna. When Arjuna saw that Aśvatthāmā was releasing various kinds of arrows to hurt Kṛṣṇa, he immediately stood in front of Kṛṣṇa to intercept all of them. At that time, although Arjuna was being harmed by those arrows, he felt an ecstatic love for Kṛṣṇa, and the arrows appeared to him like showers of flowers.
