What is religious fight and where does it come from?
It generally comes from the core of our self-love. When we are prompted by the love of ourselves, falsely or otherwise that our possession of spiritual knowledge or holy ability are superior than others. But even whatever apparent disadvantage we may suffer in making comparison, our self-love favors us. In its extreme, such comparison might emit energy since potential energy is also hidden inside religion. In such case, according to law of transformation of energy, religious energy can transform into physical energy. This is where fighting and killing of fellow human lies, caused by fleshly forces caused by religious energy.
