Thou hast asked about the "Tablet of Chrysolite" and the "Preserved Tablet". By the "Chrysolite Tablet" is meant the Book of Bahá'u'lláh's Covenant which is the Preserved Tablet. It was hidden and preserved, now it is made manifest and resplendent. The Chrysolite Tablet is recorded and enshrined in the inmost recesses of the Book of the Covenant. ('Abdu'l-Bahá, from a Tablet -- translated from the Persian); Compilation ‘Hidden Words: References of ‘Abdu’l-Bahá and Shoghi Effendi’, prepared by the Research Department of the Universal House of Justice)

The "Preserved Tablet" is a spiritual expression and has no actual existence. It sometimes refers to the Manifestation Himself, Whose knowledge encompasses the knowledge of the former and the latter generations. (In the handwriting of Shoghi Effendi on the margin of an incoming letter dated 8 July 1929, instructing his secretary -- translated from the Persian); Compilation ‘Hidden Words: References of ‘Abdu’l-Bahá and Shoghi Effendi’, prepared by the Research Department of the Universal House of Justice)
