The four formless jhanas are:
Dimension of Infinite Space - In this dimension the following qualities are "ferreted out":[37] "the perception of the dimension of the infinitude of space, singleness of mind, contact, feeling, perception, intention, consciousness, desire, decision, persistence, mindfulness, equanimity, & attention".[37]
Dimension of Infinite Consciousness - In this dimension the following quailities are "ferreted out":[37] "the perception of the dimension of the infinitude of consciousness, unification of mind, contact, feeling, perception, intention, consciousness, desire, decision, persistence, mindfulness, equanimity, & attention".[37]
Dimension of Nothingness - In this dimension the following qualities are "ferreted out":[37] "the perception of the dimension of nothingness, singleness of mind, contact, feeling, perception, intention, consciousness, desire, decision, persistence, mindfulness, equanimity, & attention"
Dimension of Neither Perception nor Non-Perception No qualities to be "ferreted out" are being mentioned for this dimension.[37]
Although the "Dimension of Nothingness" and the "Dimension of Neither Perception nor Non-Perception" are included in the list of nine Jhanas taught by the Buddha, they are not included in the Noble Eightfold Path. Noble Path number eight is "Samma Samadhi" (Right Concentration), and only the first four Jhanas are considered "Right Concentration". If he takes a disciple through all the Jhanas, the emphasis is on the "Cessation of Feelings and Perceptions" rather than stopping short at the "Dimension of Neither Perception nor Non-Perception".
Nirodha-Samapatti
The Buddha also rediscovered an attainment beyond the dimension of neither perception nor non-perception, Nirodha-Samapatti, the "cessation of feelings and perceptions".[37] This is sometimes called the "ninth jhāna" in commentarial and scholarly literature.[38][39]
Mastering the jhanas
Gradual development
The scriptures state that one should not seek to attain ever higher jhānas but master one first, then move on to the next. Mastery of jhāna involves being able to enter a jhāna at will, stay as long as one likes, leave at will and experience each of the jhāna factors as required. They also seem to suggest that lower jhāna factors may manifest themselves in higher jhāna, if the jhānas have not been properly developed. The Buddha is seen to advise his disciples to concentrate and steady the jhāna further.
The early suttas state that "the most exquisite of recluses" is able to attain any of the jhānas and abide in them without difficulty. This particular arahant is "liberated in both ways:" he is fluent in attaining the jhānas and is also aware of their ultimate unsatisfactoriness. If he were not, he would fall into the same problem as the teachers from whom the Buddha learned the spheres of nothingness and neither perception nor non-perception, in seeing these meditative attainments as something final. Their problem lay in seeing permanence where there is impermanence.[40]
Aspects of jhana mastery
A meditator should first master the lower jhānas, before they can go into the higher jhānas. There are five aspects of jhāna mastery:
Mastery in adverting: the ability to advert[clarification needed] to the jhāna factors one by one after emerging from the jhāna, wherever he wants, whenever he wants, and for as long as he wants.
Mastery in attaining: the ability to enter upon jhāna quickly.
Mastery in resolving: the ability to remain in the jhāna for exactly the pre-determined length of time.
Mastery in emerging: the ability to emerge from jhāna quickly without difficulty.
Mastery in reviewing: the ability to review the jhāna and its factors with retrospective knowledge immediately after adverting to them.
Access concentration
According to the Pāli canon commentary, access/neighbourhood concentration (upacāra-samādhi) is a stage of meditation that the meditator reaches before entering into jhāna. The overcoming of the five hindrances[note 5] mark the entry into access concentration.[citation needed] Access concentration is not mentioned in the discourses of the Buddha, but there are several suttas where a person gains insight into the Dhamma on hearing a teaching from the Buddha.[note 6][note 7]
According to Tse-fu Kuan, at the state of access concentration, some meditators may experience vivid mental imagery,[note 8] which is similar to a vivid dream. They are as vividly as if seen by the eye, but in this case the meditator is fully aware and conscious that they are seeing mental images. According to Tse-fu Kuan, this is discussed in the early texts, and expanded upon in Theravāda commentaries.[42]
According to Venerable Sujivo, as the concentration becomes stronger, the feelings of breathing and of having a physical body will completely disappear, leaving only pure awareness. At this stage inexperienced meditators may become afraid, thinking that they are going to die if they continue the concentration, because the feeling of breathing and the feeling of having a physical body has completely disappeared. They should not be so afraid and should continue their concentration in order to reach "full concentration" (jhāna).[43]
Jhana and liberation
Main articles: Enlightenment in Buddhism and Nirvana
The Buddhist tradition has incorporated two traditions regarding the use of jhana.[3][page needed] There is a tradition that stresses attaining insight (bodhi, prajna, kensho) as the means to awakening and liberation. According to the Theravada tradition dhyana must be combined with vipassana,[44] which gives insight into the three marks of existence and leads to detachment and "the manifestation of the path".[45]
But the Buddhist tradition has also incorporated the yogic tradition, as reflected in the use of jhana, which is rejected in other sutras as not resulting in the final result of liberation. One solution to this contradiction is the conjunctive use of vipassana and samatha.[46] In Zen Buddhism, this problem has appeared over the centuries in the disputes over sudden versus gradual enlightenment.[47][page needed]
Various possibilities for liberation
Schmithausen notes that the mention of the four noble truths as constituting "liberating insight", which is attained after mastering the Rupa Jhanas, is a later addition to texts such as Majjhima Nikaya 36.[12][3][page needed][2][page needed] Schmithausen discerns three possible roads to liberation as described in the suttas, to which Vetter adds a fourth possibility:[48]
Mastering the four Rupa Jhanas, where-after "liberating insight" is attained;
Mastering the four Rupa Jhanas and the four Arupa Jhanas, where-after "liberating insight" is attained;
Liberating insight itself suffices;
The four Rupa Jhanas themselves constituted the core liberating practice of early Buddhism, c.q. the Buddha.[49]
Jhana itself is liberating
Both Schmithausen and Bronkhorst note that the attainment of insight, which is a cognitive activity, can't be possible in state weherin all cognitive acitivy has ceased.[3] According to Vetter, the practice of Rupa Jhana itself may have constituted the core practice of early Buddhism, with practices such as sila and mindfulness aiding to its development.[49] It is the "middle way" between self-mortification, ascribed by Bronkhorst to Jainism,[50] and indulgence in sensual pleasure.[51] Vetter emphasizes that dhyana is a form of non-sensual happiness.[52] The eightfold path can be seen as a path of preparation which leads to the practice of samadi.[53]
Liberation in Nirodha-Samapatti
According to some texts, after progressing through the eight jhanas and the stage of Nirodha-Samapatti, a person is liberated.[37] According to some traditions someone attaining the state of Nirodha-Samapatti is an anagami or an arahant.[54] In the Anupadda sutra, the Buddha narrates that Sariputta became an arahant upon reaching it.[55]
Jhana as an aid to attaining insight
Main articles: Vipassana and Sampajañña
Dhyana and insight
According to Alexander Wynne, the ultimate aim of dhyana was the attainment of insight,[56] and the application of the meditative state to the practice of mindfulness.[56] According to Frauwallner, mindfulness was a means to prevent the arising of craving, which resulted simply from contact between the senses and their objects. According to Frauwallner, this may have been the Buddha’s original idea.[57] According to Wynne, this stress on mindfulness may have led to the intellectualism which favoured insight over the practice of dhyana.[58]
Two kinds of dhyana
According to Richard Gombrich, the sequence of the four rupa-jhanas describes two different cognitive states:
I know this is controversial, but it seems to me that the third and fourth jhanas are thus quite unlike the second.[59][note 9]
Alexander Wynne further explains that the dhyana-scheme is poorly understood.[58] According to Wynne, words expressing the inculcation of awareness, such as sati, sampajāno, and upekkhā, are mistranslated or understood as particular factors of meditative states,[58] whereas they refer to a particular way of perceiving the sense objects:[58]
Thus the expression sato sampajāno in the third jhāna must denote a state of awareness different from the meditative absorption of the second jhāna (cetaso ekodibhāva). It suggests that the subject is doing something different from remaining in a meditative state, i.e. that he has come out of his absorption and is now once again aware of objects. The same is true of the word upek(k)hā: it does not denote an abstract 'equanimity', [but] it means to be aware of something and indifferent to it […] The third and fourth jhāna-s, as it seems to me, describe the process of directing states of meditative absorption towards the mindful awareness of objects.[60][note 10]
Theravada-tradition
According to the Theravada-tradition, the meditator uses the jhāna state to bring the mind to rest, and to strengthen and sharpen the mind, in order to investigate the true nature of phenomena (dhamma) and to gain insight into impermanence, suffering and not-self.[citation needed]
According to the sutta descriptions of jhāna practice, the meditator does not emerge from jhāna to practice vipassana but rather the work of insight is done whilst in jhāna itself. In particular the meditator is instructed to "enter and remain in the fourth jhāna" before commencing the work of insight in order to uproot the mental defilements.[61]<[note 11]
According to the later Theravāda commentorial tradition as outlined by Buddhagoṣa in his Visuddhimagga, after coming out of the state of jhāna the meditator will be in the state of post-jhāna access concentration. In this state the investigation and analysis of the true nature of phenomena begins, which leads to insight into the characteristics of impermanence, suffering and not-self arises.[citation needed]
According to the contemporary Vipassana-movement, the jhāna state cannot by itself lead to enlightenment as it only suppresses the defilements. Meditators must use the jhāna state as an instrument for developing wisdom by cultivating insight, and use it to penetrate the true nature of phenomena through direct cognition, which will lead to cutting off the defilements and nibbana.[citation needed]
Insight alone suffices
The emphasis on "liberating insight" alone seems to be a later development, in response to developments in Indian religious thought.[3][49] Vetter notes that such insight is not possible in a state of dhyana, since discursive thinking is eliminated in such a state.[63] He also notes that the emphasis on "liberating insight" developed only after the four noble truths were introduced as an expression of what this "liberating insight" constituted.[64] In time, other expressions took over these function, such as pratītyasamutpāda and the emptiness of the self.[65]
In Mahāyāna traditions
Mahāyāna Buddhism includes numerous schools of practice. Each draw upon various Buddhist sūtras, philosophical treatises, and commentaries, and each has its own emphasis, mode of expression, and philosophical outlook. Accordingly, each school has its own meditation methods for the purpose of developing samādhi and prajñā, with the goal of ultimately attaining enlightenment.
Dhyāna in Chan Buddhism
See also: Zen, Chan Buddhism, Zen, Korean Seon and Zen in the United States
In China, the word dhyāna was originally transliterated with Chinese: 禪那; pinyin: chánnà and shortened to just pinyin: chán in common usage. In Chinese Buddhism dhyāna may refer to all kinds of meditation techniques and their preparatory practices which can be used to attain samadhi.[66] The word chán became the designation for Chan Buddhism (Korean Seon, Zen). The word and the practice of meditation entered into Chinese through the translations of An Shigao (fl. c. 148-180 CE), mainly the Dhyāna sutras, which were influential early meditation texts.
Dhyāna is a central aspect of Buddhist practice in Chan. Nan Huai-Chin:
Intellectual reasoning is just another spinning of the sixth consciousness, whereas the practice of meditation is the true entry into the Dharma."[67]
According to Sheng Yen, meditative concentration is necessary, calling samādhi one of the requisite factors for progress on the path toward enlightenment.[68]
Vajrayāna
B. Alan Wallace holds that modern Tibetan Buddhism lacks emphasis on achieving levels of concentration higher than access concentration.[69][70] According to Wallace, one possible explanation for this situation is that virtually all Tibetan Buddhist meditators seek to become enlightened through the use of tantric practices. These require the presence of sense desire and passion in one's consciousness, but jhāna effectively inhibits these phenomena.[69]
While few Tibetan Buddhists, either inside or outside Tibet, devote themselves to the practice of concentration, Tibetan Buddhist literature does provide extensive instructions on it, and great Tibetan meditators of earlier times stressed its importance.[71] All this being said, Wallace has translated and commented on Tsongkapa's Stages of the Path, a Tibetan classic on this topic, in his book Balancing the Mind. It is a very intricate guide on mastering equanimity and insight during meditation, both of which are claimed to be required to advance up the jhanas.
Influence on Indian religions
Jhana as liberation
Hindu texts later used that term to indicate the state of liberation. According to Walshe, citing Rhys Davids, this is not in conformity with Buddhist usage:[72][page needed]
its subsequent use in Hindu texts to denote the state of enlightenment is not in conformity with Buddhist usage, where the basic meaning of concentration is expanded to cover ‘meditation’ in general.[8][page needed]
But according to Vetter, the practice of dhyana may have been the original liberating practice in Buddhism.[2][page needed]
Parallels with Patanjali's Ashtanga Yoga
See also: Yoga Sutras of Patanjali § Buddhism
There are parallels with the fourth to eighth stages of Patanjali's Ashtanga Yoga, as mentioned in his classical work, Yoga Sutras of Patanjali,[73] which were compiled around 400 CE by, taking materials about yoga from older traditions.[74][75][76]
Patanjali discerns bahiranga (external) aspects of yoga namely, yama, niyama, asana, pranayama, and the antaranga (internal) yoga. Having actualized the pratyahara stage, a practitioner is able to effectively engage into the practice of Samyama. At the stage of pratyahara, the consciousness of the individual is internalized in order that the sensations from the senses of taste, touch, sight, hearing and smell don't reach their respective centers in the brain and takes the sadhaka (practitioner) to next stages of Yoga, namely Dharana (concentration), Dhyana (meditation), and Samadhi (mystical absorption), being the aim of all Yogic practices.[77]
The Eight Limbs of the yoga sutras show Samadhi as one of its limbs. The Eight limbs of the Yoga Sutra was influenced by Buddhism.[78][79] Vyasa's Yogabhashya, the commentary to the Yogasutras, and Vacaspati Misra's subcommentary state directly that the samadhi techniques are directly borrowed from the Buddhists' Jhana, with the addition of the mystical and divine interpretations of mental absorption.[80][not in citation given] However, it is also to be noted that the Yoga Sutra, especially the fourth segment of Kaivalya Pada, contains several polemical verses critical of Buddhism, particularly the Vijñānavāda school of Vasubandhu.[81]
The suttas show that during the time of the Buddha, Nigantha Nataputta, the Jain leader, did not even believe that it is possible to enter a state where the thoughts and examination stop.[82]
Scientific studies
There has been little scientific study of these mental states. In 2008, an EEG study found "strong, significant, and consistent differences in specific brain regions when the meditator is in a jhana state compared to normal resting consciousness".[83] Tentative hypotheses on the neurological correlates have been proposed, but lack supporting evidence.
