The explanation of revelation and ascension in Mulla Sadra’s view is tied to the concept of revelation and intuitive knowledge; therefore, in this study, we have examined these related concepts. Mulla Sadra did not explain his views on each of these concepts in a systematic way and in one text. However, we can get a clear picture of his view on this subject matter by examining and categorizing his collection of words.  For him, ascension is the result of sincere deeds that strengthen the mystic’s soul and prepare the ground for his connection to the transcendental world and unity with supreme causes. Since, according to Mulla Sadra, all existence is the existence of a single person, the mystic can dominate the orders of existence with this spiritual evolution. From this viewpoint, revelation is merely a kind of formal apocalypse and ascension is also explainable, and Mulla Sadra sought to answer some doubts about the physical ascension of the Prophet by using some philosophical findings such as an ideal body.
