Haribhadrasuri’s Saddarsana Samuccaya delineates six primary philosophical systems, urging scholars to grasp their distinct guiding deities and core principles. While acknowledging numerous sub-sects and doctrines, the work emphasizes these six as foundational. Variations arise within Buddhist and Jaimini schools, but each sub-school ultimately traces back to the core categories. Understanding these distinctions is crucial for comprehending the uniqueness of each philosophical thought within the broader spiritual landscape.
