Light and darkness in Khosravani's wisdom with Henry Corben's metaphysics and Bayazid Bastami's mysticism

The two-part world of light and darkness has a long history. In the imagination of ancient Iranians, there are two principles in eternity; One was called Ahura Mazda and the other Ahriman. The research question is, what is the foundation of light and darkness in Khosravani's wisdom? And how are these two concepts explained in Bayezid's sayings and Hanry Corben's metaphysics? The purpose of this research is to explain the nature of light and darkness in Bayezid's mysticism and its connection with Khosravani's wisdom and to reflect this category with Hanry Corben's worlds in the ancient Iran. The findings of the research are that the dualities of light and darkness are two separate essences with different natures, which were correct in the wisdom of Khosravani and the mysticism of Bayazid Bastami. HanryCorben connects the metaphysics of Suhrawardi's thought with German romanticism, Mazdaism, Manichaeism, Hermesis, and the Sufism of Rozbehan Baghli, NajmuddinKobra, and NajmuddinRazi. Mazdasna's worldview is based on light and darkness. Light is the appearance of the self and the appearance of others. Darkness is also the essence of dark and has a dark aspect. The hero of mystical thought is a light man trapped in darkness who is thinking of liberation. His idea and experience are also connected in the connection of light man and his guide. Bayezid also meant God's light and the achievement of it in his mystical thinking.
