You can not find peace by searching, you can't invent peace with a mere intellect. So where is the peace that almost everyone sought-after?
It is within yourself!
Yes, it sounds simple yet hard to swallow. Some people cultivated their inner mind to bring about this so called peace. Other just find it neglected and realized soon after they saw their own foolishness.
Peace is there, whether you see it or not, whether you believe it or not, whether you pray for it or not.
Some will need faith just to make imagination of their selves in a state of peace. Some will throw away faith so they can see peace as naked as they are.
In the end, one should see peace for oneself. Nobody can bring it to you except yourself.
