Among the signs of enkindlement, of grace and edification, of cheer and spirituality, is gathering in the Mashriqu’l-Adhkár at the hour of dawn and offering supplications and prayers in that majestic and luminous Temple. This matter is important and will produce great results. The mere gathering of the friends at dawntide in the Mashriqu’l-Adhkár shall demonstrate the power of the Cause, display the potency and influence of the Word of God, evince the attachment of the hearts to the divine commandments, and clearly manifest the turning of the souls towards the shore of His oneness. Negligence and indifference with respect to this pious act are in no wise permitted.
