Even this mood of anger is there in the Personality of Godhead. He is angry when His pure devotee who are simply dedicated to preaching this message and delivering the fallen souls from their misery, are tortured is harassed and… in so many ways offended and mistreated. Then He becomes angry.
Therefore Caitanya Mahaprabhu advised that vaisnava aparaad mata haathi.. that the MAD ELEPHANT offense is to offend the Vaisnava. Just like an elephant goes into the garden and uproots and those branches being uprooted their leaves dry.
Similarly by offending Vaisnavas, great devotees of Lord Caitanya Mahaprabhu, Lord Krishna, Lord Vishnu, this destroys one’s spiritual progress.”HH Jayapataka Swami Lecture
