August 15

O ye friends of God! The real friends are the skillful physicians and the divine instructions are the antidote of the Merciful One and the remedies of the hearts. They (the believers) heal the nostril affected with rheum, make mindful the negligent ones, give a share to the deprived ones and make hopeful the hopeless ones. In this day if anyone liveth in accord with the heavenly teachings and instructions, he shall become a spiritual physician to the world of humanity and the trumpet of Israfel [1] to quicken the dead; for the confirmations of the Kingdom of Abha are uninterrupted and the victory of the Supreme Concourse is the associate of every one who is pure in heart. The weak gnat will become the strong royal falcon and the sparrow is transformed into the eagle soaring toward the apex of the Ancient Glory. Therefore, look ye not upon your own capability and merit, nay rather, lay your confidence in the bounty and protection, favor and grace of the Blessed Perfection—may my life be a sacrifice to His beloved ones!—and, mounting upon the charger of magnanimity, rush ye toward the arena of martyrdom, so that ye may win the polo of favors in this vast field of God!
