The round of center on these drawings present 'true-self' and outside round bulk is 'ego'. Whatever one does, its' ego is moving toward self which means that true self and surface living self can't meet up there. One doesn't even notice of true self. It brings total disorder and confusion about life. This is the first drawing. In second drawing one knows there is true self and ego is different thing from oneself. However one is still caught up with old habit of pleasure or grief. The center is still in the process of keep moving. And the third one is knowing self and using awareness of ego for life; it is universal nature. It exists without center in the center.
