We don't realize the fear of our emotions. Lets consider fear is an imaginary shield of our positive thoughts. Fear pushes us into not taking certain kinds of risks. Fear is full of expectations. With fear we do things because we expect that others are going to do the same.
Fear has no justice.
Fear is action that can only produce suffering. You pay many times for the same mistake because of fear. Fear is full of pity. Just by seeing where you are, just by changing your attention, everything around you will change. Once people understands what fear is than we can be happy.
