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.
Solitude and loneliness are not the same thing. Loneliness is the sign that something is lacking. The purpose of solitude is to bring us home to the center of ourselves with such serenity that we could lose everything and, in the end, lose nothing of the fullness of life at all. When you are alone, are you lonely or are in solitude? If loneliness is what it's about, what you may need most is the cultivation of the richness of solitude.
