You have two forces pulling you in different directions : Logic (black lines) and Feelings(red lines). If you go by the Logic only, your life would be deserted and sterile (the right parts of the painting). If you succumb to your feelings, you would get overwhelmed by them. And eventually you would be drawn in chaos(the left parts of the painting). But if you keep to the middle (the center parts of the painting), avoiding extremities, your life will flourish. Balance is everything.
