The majority of the divan poets who lived in the classical period successfully handled religious, especially mystical, thought in their poems, along with the so-cial, political or literary understanding of the society they were in. This thought was sometimes expressed under the influence of theology and philosophy, while at other times, it manifested under the influence of sects such as Mevleviyya, Akbariyya, Naqshbandiyya, and Gulshaniyya. One of the poets who centered re-ligious thought in his poetry was Usûlî (d. 1538). According to the information provided by biographical sources, Usûlî was born in Yenice-i Vardar. Despite receiving a solid education in both religious and ratio-nal sciences in Yenice, he did not complete his madrasah studies and traveled to Egypt with the intention of becoming a dervish at the lodge of İbrahim Gülşenî (Mustafa Âlî, 1994: 193; Latîfî, 2000: 175). After the death of İbrahim Gülşenî, he returned to Yenice and devoted the rest of his life to spreading the Gülşenî order in Rumelia alongside Evrenosoğlu Abdi Bey (Çelebi, 2010: 344).
