Do you man the benefits like being tortured and having attempts on His life and being exiled and imprisoned for almost 40 years?
Baha'u'llah only lived in a mansion for the last few years of His life.
.. but that doesn't mean all good writers and talkers are scammers.
No scammer could make up all of what Baha'u'llah wrote about God and so many other things, nor wouldh e have any reason to do so.
I have mentioned many a times that Bahaollah was imprisoned just for four months (Siyah Chal, Tehran). He had strong support of the Ottomans and the British for political reasons. Elsewhere he was a detainee with restrictions on his free travel and not imprisoned.
"Bahá’u’lláh left the Riḍván garden on 3 May 1863 and proceeded with his family to Constantinople
as guests of the Ottoman government, accompanied by a mounted government escort arranged for their protection by 'Ali Pasha, the Sultan’s prime minister. Other travelers included at least two dozen companions who requested Bahá’u’lláh’s permission to accompany him. After fifteen weeks Bahá’u’lláh arrived in the Ottoman capital on 16 August 1863. He was welcomed by various government ministers of the Sultan, and by prominent personalities who paid their respects."
He lived for four and a half years in Adrianople with his family and followers. Then they were moved to Akka barracks which were no less than a mansion. Mirza Mehdi died by a fall in Akka, but such accidents can happen anywhere. After 1871, his family was allowed to move to the town from the barracks. Then 1877-79 at Mazarih.
Though formally still a prisoner of the Ottoman Empire, the final years of Baháʼu'lláh's life (1879–1892) were spent in the
Mansion of Bahjí, just outside ‘Akká.
Yeah, all speakers and writers are not scammers, but there is no evidence that Bahaollah was not one. The reason as I have mentioned was being leader of a group and passing that leadership to his progeny. In case of Bahaollah, it lasted two generations.
Adrianople Mansion, Majarih, Bahji Mansion, Akka Barracks. (I agree that these building may not have this shape when Bahaollah lived there)
