Maturity

Every child is born innocent, but every child is made knowledgeable by society. Hence schools, colleges, universities exist; their function is to destroy you, to corrupt you.
Maturity means gaining your lost innocence again, reclaiming your paradise, becoming a child again. Of course it has a difference - the ordinary child is bound to be corrupted, but when you reclaim your childhood you become incorruptible. Nobody can corrupt you, you become intelligent enough - now you know what the society has done to you and you are alert and aware, you will not allow it to happen again.
