Comparison between Heidegger and Mulla Sadra's viewpoint about "Existence"

This article studies common aspects and differences between Heidegger, contemporary German philosopher, with Persian philosopher, Mulla Sadra 17th century equivalent to 11th Islamic century. The origin point for Mulla Sadra and Heidegger is "existence". However, Mulla Sadra believe in "existence unity" whereas Heidegger tries to understand the concept of "existence" by special being, i.e. human being. Both of them believe in supposing the concept of human without world is wrong, they believe in dichotomy of mind, being is wrong, and there is a unity between objective and sane. Both reached from thing to being, but Heidegger by "Phenomenology", and Mulla Sadra by "metaphysics." Both believe in priority of existence before nature, or virtual validity of nature. Although Heidegger considers existence just for threshold, and Mulla Sadra believes origin of existence is the same and it includes for all beings versus of null. Briefly, for Heidegger same as Hegel, being as being has no value, whereas for Mulla Sadra this type of being is highest grade of existence. Heidegger returns into illumination, while his illumination is different from Mulla Sadra's illumination, his illumination is same as Buddhism "human for human" not from higher world for human. According to Heidegger, existence changes have cultural and historical meaning. Whereas according to Mulla Sadra the concept of existence is common, meaning and it is understood with illumination
