A,An,The..

A corner of shade,
A nook of comfort.
A guilt of the past,
A trouble of the present.
An invisible dream,
An united world of joy.
An enmity lost in smile,
An omnipresent blessing.
The simple beats of heart,
The feeble excitement at start.
The roar of self in humility,
The money never turned greedy.
A river of goodness for all,
A benign surge for life's call.
