It ill beseemeth thee to turn thy gaze unto former or more recent times. Make thou mention of this Day and magnify that which hath appeared therein. It will in truth suffice all mankind. Indeed expositions and discourses in explanation of such things cause the spirits to be chilled. lt behoveth thee to speak forth in such wise as to set the hearts of true believers ablaze and cause their bodies to soar.
Teach thou the Cause of God with an utterance which will cause the bushes to be enkindled, and the call "Verily, there is no God but Me, the Almighty, the Unconstrained" to be raised therefrom. Say: 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. Meditate upon that which hath streamed forth from the heaven of the Will of thy Lord, He Who is the Source of all grace, that thou mayest grasp the intended meaning which is enshrined in the sacred depths of the Holy Writings. (Baha’u’llah, Lawh-i-Hikmat, published in ‘Tablets of Bahá'u'lláh Revealed after the Kitab-i-Aqdas’; The Compilation of Compilations, vol. II, Writers and Writing)
