“The five-pointed star, or haykal (Arabic: temple‎) is the symbol of the Baháʼí Faith as mentioned by Shoghi Effendi, head of the Baháʼí Faith in the first half of the 20th century: "Strictly speaking the 5-pointed star is the symbol of our Faith, as used by the Báb and explained by Him."[1] The five-pointed star has been used as the outline of special letters or tablets by both the Báb[2] and Baháʼu'lláh.[3]

Haykal is a loan word from the Hebrew word hēyḵāl, which means temple and specifically Solomon's Temple in Jerusalem. In Arabic, the word also means the body or form of something, particularly the human body.[4] In the Baháʼí tradition, the haykal was established by the Báb — who told of Baháʼu'lláh's coming — who represented the haykal as a five-pointed star representing the human body as a head, two hands, and two feet.[4][5] The Báb wrote many letters, tablets, prayers and more in the shape of a five-pointed star, including some that included many derivatives of the word Baháʼ (see below).[6][7]

In Baháʼu'lláh's writings, specifically the Súriy-i-Haykal (Tablet of the Temple), while the meaning of temple remains present, the haykal is used mainly to mean the human body, but particularly the body of the Manifestation of God — a messenger from God — and the person of Baháʼu'lláh himself.[4] In the Tablet, the haykal is also used to refer to the word of God, which is revealed by the Manifestations of God.[8] He also says in the same Tablet:

This part of the symbol comprises three levels, each level indicated by a number. Together they represent the underlying belief which is the basis of all the religions of God. They are as follows:

(1) The World of God – The Creator
(2) The World of the Prophets or Manifestation – Cause, or Command
(3) The World of Man – Creation.

The followers of all religions believe that man, left to himself, can never recognize God and attain His presence; nor is man able to fathom the mystery and purpose of his own creation. God, in His unlimited bounty has singled out His Chosen Ones and will continue to do so, sending them to man at different times and ages in order to grant him penetrating insight and to enable him to have a glimpse of the unfading glories of the innumerable worlds beyond.

The Prophets accept descent from their realms on high and suffer the abasement of living in human temples, walking amongst men and speaking their languages. The Manifestations are invariably denied, ridiculed, humiliated and even put to death. Were it not for their spiritual upliftment and leadership, man would have continued to live as a wild beast and would have been eternally doomed to deprivation and loss.

These functions of the Prophets are clearly demonstrated in the design of the Greatest Name by having the world of the Prophets (shown in horizontal line) repeated in vertical line, thus joining the world of the Creator to that of His creation.
