As the administrative work of the Cause steadily expands, as its various branches grow in importance and number, it is absolutely necessary that we bear in mind this fundamental fact that all these administrative activities, however harmoniously and efficiently conducted, are but means to an end, and should be regarded as direct instruments for the propagation of the Bahá'í Faith. Let us take heed lest in our great concern for the perfection of the administrative machinery of the Cause, we lose sight of the Divine Purpose for which it has been created. Let us be on our guard lest the growing demand for specialization in the administrative functions of the Cause detain us from joining the ranks of those who in the forefront of battle are gloriously engaged in summoning the multitude to this New Day of God. This indeed should be our primary concern; this is our sacred obligation, our vital and urgent need. Let this cardinal principle be ever borne in mind, for it is the mainspring of all future activities, the remover of every embarrassing obstacle, the fulfillment of our Master's dearest wish.
(Letter written by Shoghi Effendi dated January 10, 1926 published in Baha'i Administration, p. 102)
