Auzubillah!!! If this is not kufr than there is no such thing as kufr. Look what else this Mirza wrote:
"I saw in one of my vision that I myself am God and believed that I am Him." (Kitab-ul-Bariayh, Roohani Khazain vol. 3 p.103)
Astaghfirullah, can this be a vision from Allah, or is this a vision from Shaytan? Obviously only Shaytan will give such visions that Mirza himself is God! And Mirza says he believes that he is God! Tauba astaghfar!!!
Tauba! Astaghfirullahal lazi LaIlaha Illah huwal hayyul qayyumu wa-atubu Ilayh.
