Developed by the Sakya school of Indo-Tibetan Buddhism and systematized by Gorampa Senge, this method, "freedom from extremes," clarifies emptiness and ultimate truth. The study investigates how the negative phenomenology of Madhyamaka is implicitly enunciated through its logic, emphasizing the collapse of intentionality, the mind, and phenomena before the mind. A middle way between transcendent and semantical interpretations is proposed, with the Prajñāpāramitāsūtras playing a crucial role. The thesis establishes a framework based on the negative Catuṣkoṭi's logic, examines its structure, and explores its final negation following Gorampa's resolute reading. The phenomenological exploration delves into the intentional dimension of the negative Catuṣkoṭi's grammar, drawing upon principles of Buddhist phenomenology.Show less
