This is one of my favourite quotes; This is the mating ritual between Carpathian lifemates written by Christine Feehan.
“I claim you as my life mate. I belong to you. I offer my life for you. I give to you my protection, my allegiance, my heart, my soul, and my body. I take into my keeping the same that is yours. Your life, happiness, and welfare will be cherished and placed above my own for all time. You are my life mate, bound to me for all eternity and always in my care.”
