 Where the Indian Buddhist philosophical schools party their company, Kagyü argues, is their conception of the defined example of the ultimate. For the realists (dngos smra ba) ultimate truth is a foundational entity (rdzas su yod pa) that withstands rational analysis. The Madhyamaka rejects this and argues that if ultimate truth is a foundational entity, it is not possible to attain an awakening to it. If it is possible to attain awakening, then ultimate truth is impossible to be a foundational entity, for the two mutually exclude each other. The foundational entity, like the substance of the Brahmanical metaphysicians, does not allow modification or change to take place whereas the attainment of awakening is an ongoing process of modification and change (Mikyö Dorje 2006: 294).
