The inscription upon the Bahá’í ringstone is the symbol of the Greatest Name, Bahá who is the Manifestation of the essence of God. It is also symbolic of the three planes representing the World of God, the World of Revelation and the World of Creation.
(Shoghi Effendi, Lights of Guidance, p. 269)
The use of most great name or the ringstone symbol on gravestone is not appropriate. In a letter dated September 17, 1971 to an individual believer we wrote the following: “Concerning the question you ask in your postscript, there is no specific ruling regarding the type of headstone that may be used at a grave site. However, regarding the inscription on a headstone, the beloved Guardian asked the believers not to use any form of the greatest name but a nine pointed star may be used.
(Universal House of Justice, Lights of Guidance, p. 198)
Upon the horizon of eternal Glory two luminous stars have arisen in brilliance: one to the right and one to the left ... this is the mystery of the appearance of the Beauty of Abhá and of the Supreme Highness (the Bab). And though these two diagrams at the right and the left have form of stars, they also represent the body of man, with the head, the two arms and two legs, since this diagram has five points.
