What our eyes see is just a image,it is our heart that understand the world and everything around us. When our eyes see the world, our hearts will think the things with sharp mind.
What we see is mostly dependent on what we think in our mind.Our subjective imagination makes up a picture in our brain.So it's our heart that decides the outer things.To see the substance of things we need use our heart to feel.
One must look with the heart if he want to see something beautiful.Look by heart and feel by heart,then you will see a different world.The things which is not in natute can just be seen by the eyes of heart.
A wealthy man may feel empty while a poor man can be the most happiest guy. If we cannot see the significance inside, only look at the surface, even the whole world means nothing to us.
