The text in white appears to be a (mystic) love poem in praise of K, admiring his beauty (the mole on his lip), and e.g. “lovesick at the beauty of your eyes”, and “without the love of K you cannot love Muhammad al Mahdi (the 12th Imam)”.
And see the text in white below the image, remarkably contradicting the kind of orthodoxy we might associate with Khomieni: “They open the door of the drinking house and we go there day and night as we are sick of going to the mosque and the school.”
For information about Muhammad al Mahdi, see the Encylopedia of the Orient.
Ayatollah Seyyed Ruhollah Khomeini (Persian: آیت الله روح الله خمینی Arabic: آية الله روح الله الخميني) (May 17, 1900? – June 3, 1989) was a Shi’a Muslim cleric and marja, and the political and spiritual leader of the 1979 Iranian Revolution which saw the overthrow of Mohammad Reza Pahlavi, the last Shah of Iran. Following the Revolution, Khomeini held the office of Supreme Leader, the paramount figure in the political system of the new Islamic Republic, and retained this position until his death.
Khomeini was considered a spiritual leader to many Shi’a Muslims, and in Iran is officially addressed as Imam rather than Ayatollah, and his supporters also adhere to this convention.
