HOW DO YOU KNOW IT'S THERE IF IT ISN'T THERE...

There are so many things that we don't see but we know that it is there. Sometimes we just can feel them and sometimes we just believe them. But how can we say that it's there??? Is it through our senses? or perhaps through our thoughts. But what's in our minds exist only in our minds and therefore cannot be seen. You can't be walking in the street saying i can see what's in your mind to every person whom you're going to encounter. But then, something tells me that it's beyond senses... because emotions are there yet no one can grasp anger or hatred or pain. And so i believe that there are things that need not be questioned if they are here. For, they might be here but our insensitiveness might tell us that they aren't there.
