to consider oneself as more learned, more favoured, more accomplished, more righteous or more exalted is a mighty error and sin.

Those souls who have drunk from the sea of the utterance of the All-Merciful and are turning towards the All-High Horizon should see themselves as being of one rank and one station. Should this injunction be firmly established and be realized through the power and might of God, the world would be seen as the Abhá paradise. Verily human beings are exalted, as can be found in every Divine scripture; but to consider oneself as more learned, more favoured, more accomplished, more righteous or more exalted is a mighty error and sin.

(Lawh-i Ittihád, The Tablet of Unity, Bahá’u’lláh - provisional translation by Moojan Momen)
