Need for moderation in teaching the Cause

Moderation is indeed highly desirable. Every person who in some degree turneth towards the truth can himself later comprehend most of what he seeketh. However, if at the outset a word is uttered beyond his capacity, he will refuse to hear it and will arise in opposition. 

- Baha’u’llah  (The Compilation of Compilations, vol. II, Guidelines for Teaching)
