2 sides

::every subject is formed by many sides or faces. Like a ball, could be a billion of sides on it. Up side and down side, left side and right side, front and behind..... etc. We can see a paper has 2 faces, 2 sides, obviously. Also for the emotion, love and hate. down and high. Or dark, bright. By your side, by my side. The foundations are just fine and perfect! So how about our mind and the soul? Must be founded by many sides that we can't express, explain by our way. When everything at least in 2 sides, how about my soul? Do I have another soul to complete the perfection?
