 Within Mahayana Buddhism, there is a species of scripture which essays a descriptive hint of Ultimate Reality by using positive terminology when speaking of it.This manifestation of Buddhism is particularly marked in the Dzogchen and Tathagatagarbha forms of the religion.Nirvana, for example, is equated with the True Self of the Buddha (pure, uncreated and deathless) in some of the Tathagatagarbha scriptures, and in other Buddhist tantras (such as the Kunjed Gyalpo or 'All-Creating King' tantra), the Primordial Buddha, Samantabhadra, is described as 'pure and total consciousness' - the 'trunk', 'foundation' and 'root' of all that exists.
