Dharma is for all, like humanity. So there is no scope of any dispute or fighting. It is singular. So there cannot be any trouble. Dharma is a matter of Universal Peace.
Main aim is to convert people from one Religion to another by various means.
Because religions are many, they cannot be trouble free. Not only this but religion is a bone of contention. Whenever there is truth, peace and prosperity there is Dharma. It is practically impossible in different religions. Looks forward for quality always.
