It is very difficult to conquer over the influence of Maya, but who firmly fixed up in Krishna Conciousness cannot be a victim of Maya. Anyway, we cannot stop our fighting with Maya, neither we can expect that all our soldiers will remain unhurt. You know Arjuna's son Abhimanyu was killed in the battle in which Bhismadeva.. was a party. Fight Krishna's cause sincerely and you will be gloried with victory.
Because we are engaged in warfare with the forces of Maya, there will be casualties. Even Arjuna's son, Abhimanyu a 16-year-old boy was killed at the battle of Kuruksetra
You have asked what is the mentality of the demons who attacked New Vrndavana and why did this happen? You should know this already, that there are two classes of men, devotees and demons. The whole history is that the peaceful devotees are disturbed by the demons but that the devotees are always victorious by the grace of Krsna. In the Bhagavad-gita Krsna ordered Arjuna to declare to the whole world that His devotees would never be vanquished. And in the last verse of the Gita, Sanjaya says wherever there is Krsna and Krsna's pure devotee Arjuna there will always be opulence, victory, extraordinary power and morality—tatra srir vijayo bhutir dhruva nitir matir mama. But because we are engaged in warfare with the forces of Maya, there will be casualties. Even Arjuna's son, Abhimanyu a 16-year-old boy was killed at the battle of Kuruksetra. We should be prepared to protect the Deities and always expect Krsna's Mercy, because we are always dependent on Him and we cannot do anything on our own without Him.
