The world is an ilussion because man can only see in ilussions, we can not see the truth because it doesnt exist. We all se the world differently and persive everything diferntly because of the knolage/ experiences we have. We see things with ours eyes, then we give them meaning, in our head. The world only exists in our own mind, reality is imposible to achive. Nothingness is the fate of humanith. We live in ours mindes traped forever. Think about how our understand, how you persive, how you learn and you will see that everything is Can only be seen though our selves.
