Devotee: "However, since he was not risking rebirth of the soul, Arjuna had no reason to be afraid of being affected with sinful activities due to his killing grandfather and teacher. But at the same time, Kṛṣṇa sarcastically addressed Arjuna as mahā-bāhu, mighty-armed, because He, at least, did not accept the theory of the vaibhāṣikas which leaves aside the Vedic wisdom. As a kṣatriya, Arjuna belonged to the Vedic culture, and it behooved him that he continue to follow its principles." Twenty-seven.
Prabhupāda: He is, as a friend, He's criticizing that "You are professing to be followers of Vedic culture, and you are accepting some nonsense culture. That is not good for you."
