~**~ Innocence is your very nature. You do not have to become it, you are already it. You are born innocent. Then layers and layers of conditioning are imposed upon your innocence. Your innocence is like a mirror and conditioning is like layers of dust. The mirror has not to be achieved, the mirror is already there - or rather, here. The mirror is not lost, it is only hidden behind layers of dust.
~**~ You don't have to follow a way to reach your nature because you cannot leave your nature, you cannot go anywhere else. Even if you wanted to, it is impossible. That's exactly the definition of nature: Nature means that which cannot be left behind, that which cannot be renounced. But you can forget about it. You cannot lose it but it can be forgotten.
~**~ And that's exactly what has happened. The mirror is not lost but forgotten - forgotten because it is not functioning anymore as a mirror. Not that any defect has arisen in it, just layers of dust are covering it. All that is needed is to clean it, to remove those layers of dust.
~**~ The process of becoming innocent is not really a process of becoming, it is a process of discovering your being. It is a discovery, not an achievement. You don't attain to something new, you simply attain to that which you have always been. It is a forgotten language.
