Day of the Covenant

After His ascension, Bahá'u'lláh appointed 'Abdu'l-Bahá as the Centre of His Covenant. When friends in the East asked if a day might be observed in the Master's honor, He refused — His birthday already belonged to the Declaration of the Báb — and gave them, instead, the day of His own appointment as Centre of the Covenant. Here is a tablet from that period in which He calls the friends to be firm in that Covenant.
