In his writings, S{~COMBINING MACRON BELOW~}h{~COMBINING MACRON BELOW~}ayk{~COMBINING MACRON BELOW~}h{~COMBINING MACRON BELOW~} Ahmad-i-Ahsa'i placed great emphasis on the
Arabic letter "Vav". In The Dawn-Breakers, Nabil states that this letter
"symbolized for the Bab the advent of a new cycle of Divine Revelation,
and has since been alluded to by Baha'u'llah in the Kitab-i-Aqdas in such
passages as 'the mystery of the Great Reversal' and 'the Sign of the
Sovereign'".
The name for the letter "Vav" consists of three letters: Vav, Alif, Vav.
According to the abjad reckoning, the numerical value of each of these
letters is 6, 1 and 6 respectively. Shoghi Effendi in a letter written on
his behalf to one of the believers in the East provides an interpretation
of this verse of the Aqdas. He states that the "Upright Alif" refers to
the advent of the Bab. The first letter with its value of six, which comes
before the Alif, is a symbol of earlier Dispensations and Manifestations
which predate the Bab, while the third letter, which also has a numerical
value of six, stands for Baha'u'llah's supreme Revelation which was made
manifest after the Alif.
