In the Name of God
This servant, after that grievous event and great calamity, the ascension of His Holiness 'Abdu'l-Bahá to the Abha Kingdom, has been so stricken with grief and pain and so entangled in the troubles (created) by the enemies of the Cause of God, that I consider that my presence here, at such a time and in such an atmosphere, is not in accordance with the fulfilment of my important and sacred duties.
For this reason, unable to do otherwise, I have left for a time the affairs of the Cause both at home and abroad, under the supervision of the Holy Family and the headship of the Greatest Holy Leaf [Bahiyyih Khanum, sister of 'Abdu'l-Bahá] until, by the Grace of God, having gained health, strength, self-confidence and spiritual energy, and having taken into my hands, in accordance with my aim and desire, entirely and regularly the work of service I shall attain to my utmost spiritual hope and aspiration.
The servant of His Threshold,
Circa May, 1922 (undated).
