The method of Shoghi Effendi in writing God Passes By was to
sit down for a year and read every book of the Bahá'í Writings in Persian and
English, and every book written about the Faith by Bahá'ís, whether in
manuscript form or published, and everything written by non-Bahá'ís that
contained significant references to it. I think, in all, this must have covered
the equivalent of at least two hundred books. As he read he made notes and
compiled and marshalled his facts. Anyone who has ever tackled a work of an
historical nature knows how much research is involved, how often one has to
decided, in the light of relevant material, between this date given in one
place and that date given in another, how back-breaking the whole work is. How
much more so then was such a work for the Guardian who had, at the same time,
to prepare for the forthcoming Centenary of the Faith and make decisions
regarding the design of the superstructure of the Báb's Shrine. When all the
ingredients of his book had been assembled Shoghi Effendi commenced weaving
them into the fabric of his picture of the significance of the first century of
the Bahá'í Dispensation. It was not his purpose, he said, to write a detailed
history of those hundred years, but rather to review the salient features of
the birth and rise of the Faith, the establishment of its administrative
institutions, and the series of crises which had propelled it forward in a
mysterious manner, through the release of the Divine power within it, from
victory to victory. He revealed to us the panorama of events which, he wrote,
"the revolution of a hundred years...has unrolled before our eyes"
and lifted the curtain on the opening acts of what he asserted was one
"indivisible, stupendous and sublime drama, whose mystery no intellect can
fathom, whose climax no eye can even dimly perceive, whose conclusion no mind
can adequately foreshadow."
