One of the important topics in theoretical mysticism is the discussion of God's manifestation in the universe. Because the discussion of the unity of existence in Islamic mysticism is explained by the discussion of manifestation. Manifestation is the explanation of the relationship between the supreme truth and the beings of existence, which, in addition to Muslim mystics, the followers of the Yarsan religion also give special importance to, because they associate the emergence of the Yarsan religion with the manifestation of the truth and tie the manifestation to the issue of creation. For this reason, the manifestation of God in existence is considered one of the fundamental issues of this practice from the point of view of the followers of the Yarasan religion. Considering the claims made by some elders of the Yarsan religion aboutthe independence of the Yarsan religion from Islam or the objectivity of the Yarsan religion with Islamic mysticism, in the upcoming research, an attempt has been made to compare the discussion of manifestation in Islamic mysticism and the Yarsan religion in a descriptive-analytical way. and a library, the topic in question has been examined to prove or reject the correctness or falsity of the mentioned claims.
