The goal of healthy solitude is love: love and acceptance of ourselves as we are and where we are, and love and compassion for others.
When you slow yourself down and emanate peaceful, tranquil thoughts, you actually send the anxiety and stress out of your life. Similarly, when you meditate you bring God's silent love into your present moments. In silence and stillness God's energy will become yours. By slowing your mind and other thoughts, you allow the fastest vibrations of spirit to enter. That faster vibration is one of harmony, love, and peace.
