What brings me peace, including bike riding is the Bible..
When you start to read about The love of God, and see that he's not against us (were against him)..life start to makes sense..With the cause and effect. and the bibles wisdom on how to live at peace, simple, and joyful (even when life hurts or sickness, etc).
So I can see as the orginal poster mentioned monks have more peace then others with so called sucess.
