Nirvana through poetry? Or poetry through Nirvana?

[schelley]

Emotions were kept in a
Heartshaped box
In order to keep my sanity.

I asked myself many times
Where did you sleep last night
When you failed to call.

Everyone said you were
The man who sold the world
And had nothing to show for it.

Yet I felt there was
Something in the way
that you made me feel.

In the end, you knew nothing
About a girl
that wanted nothing but you.
