Trying to understand the system of Life
Trying to understand myself
I created the world to be an image of myself, of my mind
All of these thoughts, all of these doubts and hopes
Inside
I took out to form a new breed
A new way to be
And now I am many, so many
So much larger than ever I were
Yet, at the same time
So much smaller and more vulnarable
They all carry shards of the whole
Together they become me
I see them interact, develop
I see them take different sides
As were they different minds
Believers of different ways, and different gods
I think they will teach me something
