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)
