The main cause for disharmony is not religions. Disharmony is due to not understanding the truths therein properly. Gandhiji sang “Eshwar Allah tereo nam”. Still he could not prevent partition of India. Why? Man is always selfish and religion is like opium. When man is under its influence he does not know what he does. He feels that he is serving God by harming or hurting the other man. It is a mob frenzy that takes place. To prevent it, a lot of rational thinking on religion and proper understanding of truths in it’s necessary.
