In Bursa, Khomeini possessed a great deal of spare time, with the result that he continued his studies and for the first time moved away from the “traditional” view of clerical involvement in politics.[21] He wrote his second book, Tahrir al-Wasilah, and began to receive huge donations from Iranian supporters who already opposed the Shah’s policies.[22] The extent of donations to the Ayatollah caused the Shah and Turkish government to lift the ban on communication with his during the summer of 1965, and several clergy visited Khomeini – who was wearing secular garb – in Istanbul in 1965.[22]
