Analysis of The sweet lie

I know not of happiness
That lights up the sky;
And brings laughter
The joyful hearts that spring
On the summer field

The never ending smiles
That seem to bring envy
That stretches for miles
For I know not of happiness
That lights up the sky

What I know is the sweet lie
That puts my soul at peace
From the never ending motions
That seem to strain
My heart that ignites the train

Which keeps me up at night
To ponder on the"What If's"
Of life and the sweet lie
That gives me comfort
"It's okay"
