This thesis will construct a model of person through a comparison of ideas relating to a concept of person in the Byzantine and Pratyabhijnii traditions. Questions will be asked, such as, whether a concept of person can be constructed within these two traditions, and how can ideas developed from these traditions be utilised to construct a model of person? This thesis will provide an in depth examination of terms and concepts that will be related to a concept of person within the two traditions, examining the ontological and existential implications of those terms. This work will also develop, from a subsequent convergence of the theologies of the two traditions, a model of person that is inter-religious and dialogical. Though this work is analytical in nature, in its deconstructing philosophical and theological models relating to person, it is also constructive, taking what is useful from the Byzantine and Pratyabhijnii traditions so as to construct a new model of person through the development of the term, Atman-hypostasis which looks to understanding human personhood in the fullest mystical state (deification) within the human condition. A comparison of the two traditions has not been attempted before in relation to the theological discourse of person; neither has such an extensive examination and deconstruction of the concept person in Byzantine and Pratyabhijnii traditions been undertaken in relation to contemporary studies; neither has a construction of this type of model of person been undertaken. This work, in constructing a new term Atmanhypostasis, which emerged from this research as an outcome of the comparison of terms and ideas relating to a concept of person in both traditions, will contribute to the academic theological field of personhood and this thesis will also contribute to the field of inter-religious dialogue in developing an anthropological model that aims to overcome the barriers that separate and divide.
