Bedreddin's religious origins were as a mystic. His form of mysticism was greatly influenced by the work of Ibn al-‘Arabi, and he is known to have written a commentary of al-‘ Arabi's book "Fusus al-hikam" (The Quintessence of Wisdom). Through his writings, he developed his own form of mysticism. His most significant book, "Varidat", or "Divine Inspirations," was a compilation of his discourses which reflected on his ideas about mysticism and religion. Bedreddin was a monist, believing that reality is a manifestation of God's essence, and that the spiritual and physical worlds were inseparable and necessary to one another. As he writes in "Varidat", he believed that "This world and the next, in their entirety, are imaginary fantasies; heaven and hell are no more than the spiritual manifestations, sweet and bitter, of good and evil actions."
