Voluntary simplicity involves both inner and outer condition. It means singleness of purpose, sincerity and honesty within, as well as avoidance of exterior clutter, of many possessions irrelevant to the purpose of life. It means an ordering and guiding of our energy and our desires, a partial restraint in some directions in order to secure greater abundance of life in other directions. It involves a deliberate organization of life for a purpose.
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.
