When my father fell desperately ill in the winter of 1949-50 his condition was despaired of by his doctors. He reached a point where he seemed to have no conscious mind left, could not recognize me, his only and idolized child, at all, and had no more control over himself than if he were six months old. If I had needed any convincing on the subject of whether man has a soul or not I received conclusive proof of its existence at that time. When Shoghi Effendi would come in to see my father, although he could not speak, and gave no conscious sign whatever of the Guardian’s nearness, a flutter, a tremor, some reaction wholly ephemeral but nevertheless visible, would pass over him because of the very presence of Shoghi Effendi.
