You are...

[BellaDonna]

Your are the sun that warms my heart, the stream that replenishes my soul, the breeze that lifts my spirit, and the earth to which I am bound.

You are the heart which holds my love, the soul that is bound to mine, the mind that intrigues me, and the body for which I crave.

You are the oxygen that I breath, the life blood flowing through my veins, the beating of my heart, and the eyes through which I view the world.

You are the Yin to my Yang, the stars that guide me, the path that I follow, and my final destination.

You are the essence of my being, the one that I give myself to, the one to which I belong, and the eternal flame that burns within.

You are the one I have chosen to love with all of my heart. You, I place above all others.

Eternally yours,
~Bella
