Harvey has defended a similar view of nibbana as anidassana viññāṇa. According to Paul Williams, there is also a trend in modern Thai Theravada that argues that "nirvana is indeed the true Self (Atman; Pali: atta)". This dispute began when the 12th Supreme Patriarch of Thailand published a book of essays in 1939 arguing that while the conditioned world is anatta, nibbana is atta. According to Williams, this interpretation echoes the Mahayana tathāgatagarbha sutras. This position was criticized by Buddhadhasa Bhikkhu, who argued that the not-self (anatta) perspective is what makes Buddhism unique. Fifty years after this dispute, the Dhammakaya Movement also began to teach that nibbana is not anatta, but the "true self" or dhammakaya. According to Williams, this dhammakaya (dharma body) is "a luminous, radiant and clear Buddha figure free of all defilements and situated within the body of the meditator." This view has been strongly criticized as "insulting the Buddha’s teaching" and "showing disrespect to the Pali canon" by Prayudh Payutto (In his The Dhammakaya case) and this has led to fervent debates in Thai Buddhist circles. Another western monastic in the thai forest tradition, Ajahn Brahmāli, has recently written against all of these views, drawing on a careful study of the Nikāyas. Brahmāli concludes that the "most reasonable interpretation" of final nibbāna is "no more than the cessation of the five khandhas." Brahmāli also notes that there is a kind of samādhi that is attainable only by the awakened and is based on their knowledge of nibbana (but is not nibbana itself), this meditation is what is being referred to by terms such as non-manifest consciousness (anidassana viññāṇa) and unestablished consciousness (appatiṭṭhita viññāṇa). Bhante Sujato has written extensively to refute this idea as well. In other Buddhist schools Sthavira schools The later Buddhist Abhidharma schools gave different meaning and interpretations of the term, moving away from the original metaphor of the extinction of the "three fires". The Sarvastivada Abhidharma compendium, the Mahavibhasasastra, says of nirvana: As it is the cessation of defilements (klesanirodha), it is called nirvana. As it is the extinction of the triple fires, it is called nirvana. As it is the tranquility of three characteristics, it is called nirvana. As there is separation (viyoga) from bad odor (durgandha), it is called nirvana. As there is separation from destinies (gati), it is called nirvana. Vana means forest and nir means escape. As it is
