" ... purge thine ear, that thou mayest hearken unto My words."

"Sanctify thine heart, that thou mayest remember Me; and purge thine ear, that thou mayest hearken unto My words. Set then thy face towards the Spot wherein the throne of thy Lord, the God of Mercy, hath been established, and say: Praise be to Thee, O my Lord, for having enabled me to recognize the Manifestation of Thine own Self, and aided me to fix mine heart on the court of Thy presence, the object of my soul’s adoration. I beseech Thee, by Thy name that caused the heavens to be rent and the earth to be cleft asunder, to ordain for me what Thou didst ordain for them that have turned away from all else but Thee, and rested their hearts firmly upon Thee. Grant that I may be seated in Thy presence on the seat of truth, within the Tabernacle of Glory. Powerful art Thou to do what Thou willest. There is none other God but Thee, the All-Glorious, the All-Wise."
