November 15

To my honored and distinguished sister [the Greatest Holy Leaf] do thou convey the expression of my heartfelt, my intense longing. Day and night she liveth in my remembrance. I dare make no mention of the feelings which separation from her has aroused in my heart, for whatever I should attempt to express in writing will assuredly be effaced by the tears which such sentiments must bring to my eyes. 
(‘Abdu’l-Baha, quoted by Shoghi Effendi in a letter dated July 17, 1932; ‘Baha’i Administration’)
