Experiencing grace involves the expansion of consciousness of self to all of one's surroundings as an unbroken whole, a consciousness of awe from which negative mindstates are absent, from which healing and groundedness result. For these reasons grace has long been deemed "amazing."
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.
