Any utterance three times reported becomes a vow.

I belong to you. You possess, command, and direct every facet of my being. With my every instinct, thought, and feeling, your worship, your service, your pleasure will be my only motivation. As a mantra, I will repeat to myself my oath of devotion to you as if it were my breath –

'Mistress dear, I cherish you, I revere you, I serve you. Prostrate before you, I am your slave.' 

'Mistress dear, I cherish you, I revere you, I serve you. Prostrate before you, I am your slave.'

'Mistress dear, I cherish you, I revere you, I serve you. Prostrate before you, I am your slave.' 

With all my heart and life, I thank you for granting me the privilege of your ownership, your thralldom. Please, my Goddess, my Worship, my Mistress, my Muse, rest assured that I am with you always, even when not near. Summon me, and I will hear. With this promise, never to be forsworn, I am yours and yours alone.
