In this article we present the general principles of Proclus’ ontological system, a topic that is also interesting for how spiritual activities are formed during the fifth century A.C. Specifically, we elaborate one of Proclus’ greatest theories, the theory on the intermediate realities as well as the main methodology in which he investigates these intermediates, which refers to the triadic schema “remaining-procession-reversion”. Although there is no distinction between theory and the methodology in which it is investigated, since they are in a mutual relationship and are almost identified, we make a distinction between them to understand the Proclean system. So, both the sections of our article have a general theoretical and particularly methodological orientation. The most important aspect that we attempt to show is how through the geometrically structured pyramidal openness of the first Principle these intermediate realities, which exclude the direct communication of the absolute unity of the One-Good with the infinite variation of the natural world, are formed.
