Before making peace, war is necessary, and that war must be made with our self. Our worst enemy is our self: our faults, our weaknesses, our limitations. And our mind is such a traitor! What does it? It covers our faults even from our own eyes, and points out to us the reason for all our difficulties: others! So it constantly deludes us, keeping us unaware of the real enemy, and pushes us towards those others to fight them, showing them to us as our enemies.
