The Bab Utilized the Numerical Value of Words to Symbolize Spiritual Concepts[edit]
"The Bab made use of the numerical value of words to symbolize spiritual concepts. The Persian for 'The Letters of the Living' is 'Huruf-i-Hay'; there were 18 of these first disciples of the Bab and the numerical value of the word 'Hay' is 18. These 18 letters, together with the Bab Himself, constitute the first 'Vahid' of the Revelation. The word 'Vahid' has a numerical value of 19, and means 'Unity'. It symbolizes the unity of God, and thus the number 19 itself symbolizes the unity of God, and it was used by the Bab as the basis for His Calendar. One may also note the reference on 'The Synopsis and Codification of the Kitab-i-Aqdas' to 19 or 95 mithqals of gold or silver in connection with the laws of marriage and of Huququ'llah."
