To understand what you are as a spiritual being is to shift your perspective of your physical being. The human body is essentially a robot with soft, organic flesh controlled by an energy being. When you are born, you exert time and energy training your body to respond to your will. Eventually, the body learns to respond almost perfectly. This deep integration creates a challenge for you to recognize your dimensional consciousness as separate.
From the legend of the giant who fell in love with the moon. He knelt and cried tears of joy at the very sight of her. Yet every morning they turned to bitter weeping that she had gone. So he climbed the highest mountain he could find so that he could watch her longer. For years he knelt and wept until the mountain, in despair over his grief, turned him into stone. Yet you can still see his flow of tears.
