In one of His writings revealed in the year ’60 A.H., the Báb declares the following: “The spirit of prayer which animates My soul is the direct consequence of a dream which I had in the year before the declaration of My Mission. In My vision I saw the head of the Imám Husayn, the Siyyidu’sh-Shuhada’, which was hanging upon a tree. Drops of blood dripped profusely from His lacerated throat. With feelings of unsurpassed delight, I approached that tree and, stretching forth My hands, gathered a few drops of that sacred blood, and drank them devoutly. When I awoke, I felt that the Spirit of God had permeated and taken possession of My soul. My heart was thrilled with the joy of His Divine presence, and the mysteries of His Revelation were unfolded before My eyes in all their glory.”
