Dove Poem (Author Unknown)

Two doves meeting in the sky
Two loves hand in hand eye to eye
Two parts of a loving whole
Two hearts and a single soul
Two stars shining big and bright
Two fires bringing warmth and light
Two songs played in perfect tune
Two flowers growing into bloom
Two Doves gliding in the air
Two loves free without a care
Two parts of a loving whole
Two hearts and a single soul
