Peace is not something you can force on anything or anyone... . much less upon one's own mind. It's like trying to quiet the ocean by pressing upon the waves. Sanity lies in somehow opening to the chaos, allowing anxiety, moving deeply into the tumult, diving into the waves, where underneath, within, peace simply is.
The movement of God's Spirit is very gentle, very soft -- and hidden. It does not seek attention. But that movement is also very persistent, strong and deep. It changes our hearts radically. The faithful discipline of prayers reveals to you that you are the blessed one and gives you the power to bless others.
