That so brief a span should have separated this most mighty
and wondrous Revelation from Mine own previous Manifestation, is a secret that
no man can unravel and a mystery such as no mind can fathom. Its duration had
been foreordained, and no man shall ever discover its reason unless and until
he be informed of the contents of My Hidden Book.” - Baha’u’llah (Quoted by
Shoghi Effendi in ‘The Dispensation of Baha’u’llah’)
