It's difficult to express thoughts into complete meaningful sentences. The constant battle between the heart and mind is somehow a metaphor that best describes the battle between good and evil. You won't realize which side wants the best of you. On one side, the heart provides an emotional comfort which revolves around to give you a result driven by kindness, anger, happiness and sadness while on the other side the mind is driven by ones intellect, analytical, logic and experience. Between the two, they find a common ground of dispute - Fear. The heart fears what the mind can do and vice versa. Fear installs the Good and Evil in ones mind and heart. When ones thoughts are in sync, you can easily communicate with your inner self. But when they're not, thoughts seem to just mix itself into oblivion.
