When one takes to Krishna consciousness he or she is declaring war against the illusory energy. That war will continue right up until one becomes completely free from maya's influence. Whether the war is with parents, friends, relatives, attachments, or whatever, we will always be under attack. For a devotee, the best strategy for war is to be well protected. Duryodhana wanted Krishna's army for war. Arjuna was happy to have Krishna because as stated in Bhagavad Gita, wherever there is Krishna and wherever there is Arjuna, certainly there will be victory. Krishna will always protect that devotee who depends exclusively upon Him for protection.
