Every soul has a different response to this question and historical accounts of early believers are filled with their answers. One of the proofs of the Bab’s station that fascinates me is the sheer speed with which He revealed the Word of God. Consider the following account of the spiritually thunderstruck Mulla Husayn when the Bab declared His mission:
He took up His pen… and with incredible rapidity revealed the entire Surih of Mulk, the first chapter of His commentary on the Surih of Joseph. The overpowering effect of the manner in which He wrote was heightened by the gentle intonation of His voice which accompanied His writing. Not for one moment did He interrupt the flow of the verses which streamed from His pen. Not once did He pause till the Surih of Mulk was finished. I sat enraptured by the magic of His voice and the sweeping force of His revelation.1
I am also moved by this first-hand account of Siyyid Yahya Darabi, a learned divine:
It was still early in the afternoon when the Bab requested Haji Mirza Siyyid ‘Ali to bring His pen-case and some paper. He then started to reveal His commentary on the Surih of Kawthar. How am I to describe this scene of inexpressible majesty? Verses streamed from His pen with a rapidity that was truly astounding. The incredible swiftness of His writing, the soft and gentle murmur of His voice, and the stupendous force of His style, amazed and bewildered me. He continued in this manner until the approach of sunset. He did not pause until the entire commentary of the Surih was completed. He then laid down His pen and asked for tea.2
Not only was the speed of the Bab’s revelation a proof to those who were blessed to witness it, but it was also a fact that was championed as a verity of His station to others. Mulla Aliy-i-Bastami was a Letter of the Living and the first Babi martyr. He was punished and killed because he affirmed, in the presence of one of the leading exponents of Shi’ah Islam, that the Bab revealed in 48 hours verses equal in number to those of the Qu’ran.3 The Bab Himself stated that the rapidity with which He spoke the revealed word was constrained only by the capacity of His amanuensis.4
Furthermore, Baha’u’llah testifies in The Book of Certitude (The Kitab-i-Iqan) that,
The verses which have rained from this Cloud of Divine mercy have been so abundant that none hath yet been able to estimate their number. A score of volumes are now available. How many still remain beyond our reach! How many have been plundered and have fallen into the hands of the enemy, the fate of which none knoweth!5
Despite the Bab’s restraint, despite the loss of so many texts, and despite the fact that His ministry was so short (it was only 6 years compared to the 29 year ministry of Baha’u’llah), the quantity of the writings of the Bab are nearly equal to those of the One whose advent He proclaimed.
The Bab had two amanuenses (Siyyih Husayn and Mirza Ahmad) but He also wrote verses in His own hand. The Bab was an accomplished calligrapher of exquisite beauty. In A Traveller’s Narrative, Abdu’l-Baha describes a specimen of the Bab’s penmanship. He writes of Mulla Abdu’l-Karim, who was to deliver a box containing the Bab’s writings, ring and pen case to Baha’u’llah shortly before His execution, and who was pressured by those in his company to open the box and reveal its contents. The Master states:
Importuned by the company, he produced a long epistle in blue, penned in the most graceful manner with the utmost delicacy and firmness in a beautiful minute shikastih hand, written in the shape of a man so closely that it would have been imagined that it was a single wash of ink on the paper. When they had read this epistle [they perceived that] He had produced three hundred and sixty derivatives from the word Baha. Then Mulla Abdu’l-Karim conveyed the trust to its destination.6
When you visit the International Archives Building in Haifa, Israel you can see a “hakal” (a passage written in the shape of a five pointed star, a symbol for the human body) in the Bab’s hand. Historical distance, an inability to read Persian or Arabic, and unfamiliarity with calligraphic styles does not make seeing this priceless document a convincing experience for me, but because I am already a believer, it is still a powerfully beautiful moment. In this same vein, the answers my friends give at the dinner table are all valid and moving; once you are convinced of the Truth, all other proofs are remarkable. What is amazing are the scores of answers, the scores of proofs, not only among believers of my generation, but by believers over the course of history. This Cause is an ocean and we all submerge ourselves in different ways, from different shores, and to different depths to discover different mysteries.
