The Priceless Pearl, Ruhiyyih Khanum, p67-8
One of my most pressing problems is that of individual correspondence. To copy the Master, is presumptuous on my part, and in view of the rapid extension of the Movement, impracticable. To correspond in person with some and not write to others, I am sure you realize will lead gradually to friction, discouragement and even animosity, as you know fully well the considerable number of friends who expect much and do little. To do away utterly with individual correspondence, and rely on indirect written messages, penned by my helpers and associates, whilst I would devote my time to direct correspondence with the Assemblies throughout the world, is also a difficult problem. I would indeed value your views on this thorny problem. The latter course has the obvious objection of severing all personal relationships with the individual friends.
