Upon the reality of man, however, He hath focused the radiance of all His names and attributes, and made it a mirror of His own self. Alone of all created things man hath been singled out for so great a favour, so enduring a bounty. Spiritual progress means acquiring the capacity to act in conformity with the Will of God and to express the attributes and spirit of God in one's dealings with one's self and with other human beings. He must never seek to exalt himself above any one, must wash away from the tablet of his heart every trace of pride and vain-glory, must cling unto patience and resignation, observe silence and refrain from idle talk. For the tongue is a smoldering fire, and excess of speech a deadly poison.
Material fire consumeth the body, whereas the fire of the tongue devoureth both heart and soul.
The force of the former lasteth but for a time, whilst the effects of the latter endureth a century. That seeker should, also, regard backbiting as grievous error, and keep himself aloof from its dominion, inasmuch as backbiting quencheth the light of the heart, and extinguisheth the life of the soul. He should be content with little, and be freed from all inordinate desire. He should treasure the companionship of them that have renounced the world, and regard avoidance of boastful and worldly people a precious benefit. He should forgive the sinful, and never despise his low estate, for none knoweth what his own end shall be.
