The teacher should not consider himself as learned and
others ignorant. Such a thought breedeth pride, and pride is not conducive to
influence. The teacher should not see in himself any superiority; he should
speak with the utmost kindliness, lowliness and humility, for such speech
exerteth influence and educateth the souls.
- ‘Abdu’l-Baha (Selections from the Writings of 'Abdu'l-Bahá)
