Among his missionary activities ("dawah"), he built two mosques, Masjid Agung Cirebon and Masjid Agung Demak. His main mentor was Sunan Bonang, another of the "Wali Sanga". Kalijaga's beliefs and teaching are more sufistic than salaf, applying arts and culture as medium for his "dawah". He was also tolerant to local tradition. His exegesis from the Quranic perspective led him to believe that people will keep away from "dakwah" if their personality is questioned. In this premise one should consider a step by step approach to his people by the principle of following yet influencing. To him, if Islam is truly or fully understood, then people will gradually give up their old habits.
