Bhagwad Gita constitutes the advice given by Krishna to Arjuna. Arjuna's position then can be compared to the position of a Chief of Armed Forces of a modern country now. If at the point when war becomes inevitable between two countries the Army Chief of one country deserts his post, wouldn't his country be overrun by the enemy country? What Krishna did was to convince Army Chief Arjuna not to desert his post but to lead his forces into battle and destroy the enemy country. Wouldn't a grateful people then honour Krishna for saving the country? That's exactly Krishna's position - only he did not save merely one country, but the very concept of righteousness.
Arjuna's story is relevant to us today because often at moments when the fate of many may depend upon us doing the right thing, we fail to rise to the occasion. Understanding the principles Krishna taught to convince Arjuna to do the right thing can help us overcome our crises. Thus, a call to ban Bhagwad Gita on the ground that it promotes violence is a result of a superficial and prejudiced understanding of its message.
