Simply me

I am finite and infinite
I am everything you can see
In a smile, in a glimpse or in a gaze,
I am stardust, starlight and night
And all that matter, multiplied
By the square of the speed of light

Before I shall fade in time all over the space
And live room to you, that are following
In the trail of my steps, to find yourself
As I found me by understanding others.

And all you can see is just the top
Of the iceberg I am below in my deep ocean.
