In the earliest Upanishad, the Brihadaranyaka Upanishad, the Absolute, which came to be referred to as Brahman, is referred to as "the imperishable". The Pāli scriptures present a "pernicious view" that is set up as an absolute principle corresponding to Brahman: "O Bhikkhus! At that time Baka, the Brahmā, produced the following pernicious view: 'It is permanent. It is eternal. It is always existent. It is independent existence. It has the dharma of non-perishing. Truly it is not born, does not become old, does not die, does not disappear, and is not born again. Furthermore, no liberation superior to it exists elsewhere." The principle expounded here corresponds to the concept of Brahman laid out in the Upanishads. According to this text the Buddha criticized this notion: "Truly the Baka Brahmā is covered with unwisdom."
