Now you will ask: When the difficulties come from ourselves, where do they come from? We do not like struggle in life, we do not like strife, we only want harmony, we only want peace. It must be understood, however, that 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.
