Consider the sun.
Were it to say now, “I am the sun of yesterday,” it would speak the truth. And
should it, bearing the sequence of time in mind, claim to be other than that
sun, it still would speak the truth. In like manner, if it be said that all the
days are but one and the same, it is correct and true. And if it be said, with
respect to their particular names and designations, that they differ, that
again is true. For though they are the same, yet one doth recognize in each a
separate designation, a specific attribute, a particular character. Conceive
accordingly the distinction, variation, and unity characteristic of the various
Manifestations of holiness, that thou mayest comprehend the allusions made by
the Creator of all names and attributes to the mysteries of distinction and
unity, and discover the answer to thy question as to why that everlasting
Beauty should have, at sundry times, called Himself by different names and
titles.... (Baha’u’llah, ‘Gleanings from the Writings of Baha’u’llah’)
