To deepen in the Cause means to read the Writings of
Bahá'u'lláh and the Master so thoroughly as to be able to give it to others in
its pure form. There are many who have some superficial idea of what the Cause
stands for. They, therefore, present it together with all sorts of ideas that
are their own. As the Cause is still in its early days we must be most careful
lest we fall under this error and injure the Movement we so much adore. There
is no limit to the study of the Cause. The more we read the Writings, the more
Truths we can find in Them, the more we will see that our previous notions were
erroneous.
(From a letter dated 25 April 1926 written on behalf of Shoghi
Effendi to an individual believer; The Compilation of Compilations, vol. I, The
Importance of Deepening Our Knowledge and Understanding of the Faith)
