So I guess you are asking why
wouldn’t a delusional individual be able to do what Baha’u’lah did? Why wouldn’t it be possible?
Below are just a couple of examples, from the history of the Cause of Baha’u’llah.
I do not think a delusional individual would be able to completely rehabilitate the Babi community after it had fallen into disarray and despair, after the martyrdom of the Bab. Baha’u’llah led them and unified them and renewed their faith.
I do not think a delusional individual would be able to write on the diverse subjects that Baha’u’llah wrote in the manner that He wrote it. Here is a description of from the history:
“A certain Muhammad Karím, a native of Shíráz, who had been a witness to the rapidity and the manner in which the Báb had penned the verses with which He was inspired, has left the following testimony to posterity, after attaining, during those days, the presence of Bahá’u’lláh, and beholding with his own eyes what he himself had considered to be the only proof of the mission of the Promised One: “I bear witness that the verses revealed by Bahá’u’lláh were superior, in the rapidity with which they were penned, in the ease with which they flowed, in their lucidity, their profundity and sweetness to those which I, myself saw pour from the pen of the Báb when in His presence. Had Bahá’u’lláh no other claim to greatness, this were sufficient, in the eyes of the world and its people, that He produced such verses as have streamed this day from His pen.” God Passes By, p. 138
“As to those verses which He either dictated or wrote Himself, their number was no less remarkable than either the wealth of material they contained, or the diversity of subjects to which they referred. A vast, and indeed the greater, proportion of these writings were, alas, lost irretrievably to posterity.” God Passes By, p. 138
Another question is:
Would a delusional individual do what Baha’u’llah did? If we look at the types of delusional disorders we can see that Baha’u’llah does not fit into any of these categories.
Types of delusional disorder
There are several subtypes of delusional disorder:
- Erotomanic: People believe that another person is in love with them. They often try to contact the object of the delusion through telephone calls, letters, or digital messages. Some attempt surveillance, and stalking is common. Behavior related to the delusion may be against the law.
- Grandiose: People are convinced that they have some great talent or have made some important discovery.
- Jealous: People are convinced that a spouse or lover is unfaithful. This belief is based on incorrect inferences supported by dubious evidence. Under such circumstances, physical assault may be a significant danger.
- Persecutory: People believe that they are being plotted against, spied on, maligned, or harassed. People may repeatedly file lawsuits or reports to the police or other government agencies. Rarely, people resort to violence in retaliation for imagined persecution.
- Somatic: People are preoccupied with a bodily function or attribute, such as an imagined physical deformity or odor. The delusion can also take the form of an imagined medical disorder, such as having parasites.

Some people have the misconception that Baha’u’llah was grandiose because of his bold claims to speak for God but He was anything but grandiose. He never promoted Himself but repeatedly wrote that He did what He did
only for God.
“Incline your ears to the counsels which this Servant giveth you for the sake of God. He, verily, asketh no recompense from you and is resigned to what God hath ordained for Him, and is entirely submissive to God’s Will.” Gleanings, p. 127
“Say: God is My witness! I have wished nothing whatever for Myself. What I have wished is the victory of God and the triumph of His Cause. He is Himself a sufficient witness between you and Me. Were ye to cleanse your eyes, ye would readily perceive how My deeds testify to the truth of My words, how My words are a guide to My deeds.” Gleanings, pp. 256-257
And of course these were not just empty words because he sacrificed His Life for God, enduring imprisonment, persecution, exile and banishment for 40 years. No delusional man would do that.
“Behold Him, an exile, a victim of tyranny, in this Most Great Prison. His enemies have assailed Him on every side, and will continue to do so till the end of His life. Whatever, therefore, He saith unto you is wholly for the sake of God, that haply the peoples of the earth may cleanse their hearts from the stain of evil desire, may rend its veil asunder, and attain unto the knowledge of the one true God—the most exalted station to which any man can aspire. Their belief or disbelief in My Cause can neither profit nor harm Me. We summon them wholly for the sake of God. He, verily, can afford to dispense with all creatures.”
