For me, the difference is solitude is something you WANT and feel comfortable with, a peaceful, relaxing and inspirational space, and loneliness is an UNWANTED experience of being on your own.
I believe one of the greatest fears we have is the fear of loneliness, especially the loneliness that we feel when we are without a lover.
This fear traps many of us into unfulfilling or destructive relationships or leads us into pursuing the wrong person just to AVOID being on our own.
How many of us are in this position? how many are afraid they will be alone the rest of their lives even as they pursue their soul and soul relationship…If that is your fear that is what you are creating in your life. STOP!!!! Create what you really want not what you fear.
