Jináb-i-Karbilá’í Muḥammad-Hádí, the custodian of the Mashriqu’l-Adhkár, is my master. In other words, I am his servant, for he is a servant of the Blessed Beauty. He sweepeth the grounds of the Mashriqu’l-Adhkár. This is not servitude, but sovereignty. The service he rendereth is no mere ordinary thing; nay, it is a bounty from God, pure and true.
— 'Abdu'l-Bahá, From a Tablet translated from the Persian
