what is "A Poem"???

Poem is expression
It is full of feelings
And heals the heart
But why do we write?
I want to know…

Poem is a face
It is joy of life
And the pain of people
But why do we call it a poem?
I want to ask…

Poem is imagination
It is dream to dare
And fantasy the future
But why does it express all things?
I want to find…

Poem is a song
It is tunes of thought
And sounds of people
But who makes it?
I want to say…
