In Bhagavad-gītā, therefore, it is advised that one who desires to make tangible advancement in spiritual consciousness must avoid three things — lust, anger and the mode of passion(greed). Actually we can see that lust, anger and passion make a man crazy, even though he be as great as Dakṣa. The very name Dakṣa suggests that he was expert in all material activities, but still, because of his aversion towards such a saintly personality as Śiva, he was attacked by these three enemies — anger, lust and passion. Lord Caitanya, therefore, advised that one be very careful not to offend Vaiṣṇavas. He compared offenses toward a Vaiṣṇava to a mad elephant. As a mad elephant can do anything horrible, so when a person offends a Vaiṣṇava he can perform any abominable action.
