Concerning your second question, these two letters – the first and the second – refer to the blessed Name of the Ancient Beauty, namely B and H. What is intended by Bahá'u'lláh is this: that which is latent and enshrined within the inmost reality of these three letters has not been revealed, inasmuch as the world of being still does not possess the capacity and receptiveness to reflect fully the glorious radiance of this divine Revelation. Thus whatever is hidden in the inmost essence of the third letter of His blessed Name will gradually be unfolded before the eyes of all men.
In another sense these letters bear reference to the incalculable sufferings borne by the Blessed Beauty, while the people of the world are acquainted with but a fragment thereof.
