O ye Cohorts of God! Praise be to God! —that the Blessed Perfection hath freed the necks from the bonds and fetters and released all from racial attachments by proclaiming, “Ye are all the fruits of one tree and the leaves of one branch.” Be ye kind to the human world, and be ye compassionate to the race of man, deal with the strangers as you deal with the friends, be ye gentle toward the outsiders as you are toward the beloved ones, know the enemy as the friend, look upon the satan as upon the angel, receive the unjust with the utmost love like unto a faithful one, and diffuse far and wide the fragrances of the musk of the gazelles of Kheta and Khotan to the nostrils of the ravenous wolves.
Become ye a shelter and asylum to the fearful ones, be ye a cause of tranquility and cease to the souls and hearts of the agitated ones, impart ye strength to the helpless ones, be ye a remedy and antidote to the afflicted ones, and a physician and nurse to the sick ones. Serve ye for the promotion of peace and concord and establish in this transitory world the foundation of friendship, fidelity, reconciliation and truthfulness.
O ye Cohorts of God! Strive ye that this human world may be changed into a luminous realm and this mound of earth become the Paradise of ABHA. Darkness hath environed the world upon all sides. Savage tempers and inclination predominate. The human world has become the battlefield of the rapacious savages and the arena of the heedless and ignorant ones. The souls are either bloodthirsty wolves or beasts with degenerate reason. They are either deadly poison, or worthless plants. There are a few souls who in reality have some humanitarian intentions and are thinking of the well-being and prosperity of human kind. You must in this instance (that is, service to humanity) sacrifice your lives, and in sacrificing your lives celebrate happiness and beatitude.
