Inner peace comes from acceptance of what is. The person looking for and placing focus on “problems” is certain to find them. What sometimes makes it worse, is worrying about problems out of your control, or problems that don’t (or might not) even exist.
Example story:
Two monks are walking, and come across a destroyed wagon. The rider is beaten and bloody, and warns them of a pack of bandits in the area. After bandaging the man, they continue on.
The younger monk says “What if the bandits come upon us?” The elder monks replied “Surely our martial training will keep us safe” and kept walking.
The next day the younger monk asks “What if the bandits have guns and swords?” The elder monk says “Surely our sharp minds will prevail” and kept walking.
The third day the young monk asks “What if there are so many bandits they overwhelm us?” The elder responds “Then we shall meet our end with grace.”
They arrived at the monastery that evening, and met with the high monk there. He asked “Three days of travel, tell me what did you see?”
The younger monk says “We saw a beaten man who warned us of bandits. I spent the whole trip with my eyes and ears strained, listening for them.”
The older monk says “We walked through the Old Forest and I enjoyed the vibrant life there. We passed the Winding River, and I meditated on the fish that fight the current. We walked around the Blue Mountain and I beheld the splendours of creation.”
The high monk smiles and says to the younger monk “A bandit steals gold and food. Who then stole the forest, the river and the mountain from you?”
