Concerning the permissibility of reading selections from the
writings of the beloved Guardian at Nineteen Day Feasts in Persia: it is true,
as you rightly point out, that the beloved Guardian in a letter to the National
Spiritual Assembly of the United States stated that only the Writings of
Bahá'u'lláh and 'Abdu'l-Bahá should be read during the devotional part of the
Nineteen Day Feast...
... it should be borne in mind that the Persian writings of
Shoghi Effendi are unique in nature, and many of them, unlike his English
letters and messages addressed to the western believers, are interspersed with
supplications, prayers and homilies of a devotional character which are
suitable for the spiritual part of Bahá'í Feasts.
