The chasm between being alone and loneliness is deep. The way you begin to be alone and at peace without being lonely is to know that you are with your best friend. When you are at peace with yourself and love yourself, you can never be lonely. Only when you learn to love yourself, can you love another. You must find that love for yourself before you can touch the purity of aloneness. Love of self, without being selfish, will not allow loneliness to exist. Love of self also creates a love for everything else and brings us closer to the Sacred Oneness.
It is significant that the Latin word "templum" originally meant a vast space, open on all sides, from which one could survey the whole surrounding landscape as far as the horizon. This is what is meant to CONTEMPLATE: to "set one's sights on" Heaven from the temple that defines the field of vision... The temple is the place, the organ of vision.
