No man of wisdom can demonstrate his knowledge save by means of words. This showeth the significance of the Word as is affirmed in all the Scriptures, whether of former times or more recently. For it is through its potency and animating spirit that the people of the world have attained so eminent a position. Moreover words and utterances should be both impressive and penetrating. However, no word will be infused with these two qualities unless it be uttered wholly for the sake of God and with due regard unto the exigencies of the occasion and the people.
The Great Being saith: Human utterance is an essence which aspireth to exert its influence and needeth moderation. As to its influence, this is conditional upon refinement which in turn is dependent upon hearts which are detached and pure. As to its moderation, this hath to be combined with tact and wisdom as prescribed in the Holy Scriptures and Tablets.
Every word is endowed with a spirit, therefore the speaker or expounder should carefully deliver his words at the appropriate time and place, for the impression which each word maketh is clearly evident and perceptible. The Great Being saith: One word may be likened unto fire, another unto light, and the influence which both exert is manifest in the world. Therefore an enlightened man of wisdom should primarily speak with words as mild as milk, that the children of men may be nurtured and edified thereby and may attain the ultimate goal of human existence which is the station of true understanding and nobility. And likewise He saith: One word is like unto springtime causing the tender saplings of the rose-garden of knowledge to become verdant and flourishing, while another word is even as a deadly poison. It behoveth a prudent man of wisdom to speak with utmost leniency and forbearance so that the sweetness of his words may induce everyone to attain that which befitteth man’s station.
O friend of mine! The Word of God is the king of words and its pervasive influence is incalculable. It hath ever dominated and will continue to dominate the realm of being. The Great Being saith: The Word is the master key for the whole world, inasmuch as through its potency the doors of the hearts of men, which in reality are the doors of heaven, are unlocked. No sooner had but a glimmer of its effulgent splendour shone forth upon the mirror of love than the blessed word ‘I am the Best-Beloved’ was reflected therein. It is an ocean inexhaustible in riches, comprehending all things. Every thing which can be perceived is but an emanation therefrom. High, immeasurably high is this sublime station, in whose shadow moveth the essence of loftiness and splendour, wrapt in praise and adoration.
