The Tablets of the Divine Plan collectively refers to 14 letters (tablets) written between September, 1916 and March, 1917 by `Abdu'l-Bahá, to Bahá'ís in the United States and Canada. Included in multiple books, the first five tablets were printed in America in Star of the West - Vol. VII, No. 10, September 8, 1916, and all the tablets again after World War I in Vol. IX, No. 14, November 23, 1918, before being presented in again at the Ridván meeting of 1919.
Four of the letters were addressed to the Bahá’í community of North America and ten subsidiary ones addressed to five specific segments of that community. Of primary significance was the role of leadership given to its recipients in establishing their Cause throughout the planet by pioneering - introducing the religion into the many countries and regions and islands mentioned.
These collective letters, along with Bahá'u'lláh’s Tablet of Carmel and `Abdu'l-Bahá's Will and Testament were described by Shoghi Effendi as three of the "Charters" of the Bahá'í Faith.

"You may listen to the audio books on your computer, download them onto an mp3 player or record them onto a tape (45 minute per side) by plugging your cassette recorder into the headphones jack on your speakers. Unfortunately, we have not devised an order to the list. Thanks to the US's and UK's Bahá'í Service for the Blind for allowing us to use these tapes! The recordings are in the process of being re-digitized at a higher quality level. The file sizes are larger but the quality is significantly better. So, even you have heard them before, you might want to listen again."
