This study aims to tackle the Conceptual Blending Theory developed by Gilles Fauconnier and Mark Turner, and to apply this knowledge in analyzing metonymys and metaphors in Al- Isharat Al-Ilaheya "Divine Invocations" book by Abu Hayyan At-Tawhidi in a manner that reveals the theory's principles and examines its scope of application. The study adopts the Network Model, as the model representing this theory, since it is more appropriate for description, analysis and representation. In addition, it has a lower-degree abstraction than the theory and includes a practical side. This paper falls within the scope of cognitive semantic studies. The study assumes that analysis of metaphors in Al- Isharat Al-Ilaheya "Divine Invocations" Book according to the Network Model gives room for exploring beyond the superficial structure of this phenomenon and have and in-depth understanding of the elements that formulate these metonymys and metaphors, in addition to investigating the dominant awareness in human speech, by answering the following questions: 1. What is the relation between the Conceptual Blending Theory, Mental Spaces Theory and Conceptual Metaphor Theory? 2. How can the Network Model elements be employed to tackle metaphors in Al- Isharat Al-Ilaheya "Divine Invocations" book? 3. Can the theory be extended to build a model for tackling metaphors in the Arabic Language? The study's significance can be clarified from two perspectives, the first of which is related to the theory itself. In fact, this theory has been discussed by several researches globally, however its existence is still rare in Arabic studies. To my knowledge, there is no specialized Arabic study that discusses metaphors according to the Network Model. Accordingly, it is necessary to introduce this theory and build a model for analysis of metonymys and metaphors according to the Network Model in order to help with upgrading scientific Arabic research. The second side, on the other hand, is related to the corpus we adopted in the analysis. The book is rich in metonymys and metaphors and didn't receive due attention. So, we hope that this study خ reveals dimensions and depths of metonymys and metaphors from perspective of the modern theory. The main findings and conclusions of the study can be summarized as follows: the spaces network may never come into existence without the concept of mental space, as the multi-space model in the blending network is but an elaboration of the bi-space model in the Mental Spaces Theory. This conclusion led us to find out that the relation between the Blending Theory and Conceptual Metaphor Theory is based on the bi-space model, since Fauconnier was influenced by Lakoff and Johnson. The study concludes that the brain recalls the input spaces through finding the clear relation that links both compared items and forms a stimulus for building the network. The study finds that application reveals that metonymy in language is based on blended space cohesion, and accordingly its significance will be formed on two phases, by making the first network's blending an input to the other network. The study also reveals the three types of intensification common in metaphors: intensification as a way of shortening the chain, intensification by joining both parts of the vital relation and metaphorical intensification. Finally, the study provides a practical evidence of the efficiency of single network with harmonious frameworks in analyzing the metaphor and its important role in the metaphorical structure.
