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 way one looks at distant things
For you are only one thing among many.
And whoever sees that way heals his heart,
Without knowing it, from various ills.
