In the Pali Canon's Sutta Pitaka's first four Nikayas, Viññāṇa is one of three overlapping Pali terms used to refer to the mind, the others being manas and Citta. Each is used in the generic and non-technical sense of "mind" in general, but the three are sometimes used in sequence to refer to one's mental processes as a whole. Their primary uses are, however, distinct.
In a number of Pali texts though, the term has a more nuanced and context-specific (or "technical") meaning. In particular, in the Pali Canon's "Discourse Basket" (Suttapitaka), Viññāṇa (generally translated as "consciousness") is discussed in at least three related but different contexts:
- (1) as a derivative of the sense bases (āyatana), part of the experientially exhaustive "All" (sabba);
- (2) as one of the five aggregates (khandha) of clinging (Upadana) at the root of Suffering (Dukkha); and,
- (3) as one of the twelve causes (nidana) of "Dependent origination" (paticcasamuppāda) which provides a template for Buddhist notions of kamma, rebirth and release.
In the Pali Canon's Abhidhamma and in post-canonical Pali commentaries, consciousness (Viññāṇa) is further analyzed into 89 different states which are categorized in accordance with their kammic results.
In Buddhism, the six sense bases (Pali: Saḷāyatana; Skt.: ṣaḍāyatana) refer to the five physical sense organs (cf. receptive field) (belonging to the eye, ear, nose, tongue, body), the mind (referred to as the sixth Sense base) and their associated objects (visual forms, sounds, odors, flavors, touch and mental objects). Based on the six sense bases, a number of Mental factors arise including six "types" or "classes" of consciousness (Viññāṇa-kāyā). More specifically, according to this analysis, the six types of consciousness are eye-consciousness (that is, consciousness based on the eye), ear-consciousness, nose-consciousness, tongue-consciousness, body-consciousness and mind-consciousness.
In this context, for instance, when an ear's receptive field (the proximal stimulus, more commonly known by Buddhists as a Sense base, or sense organ) and sound (the distal stimulus, or sense object) are present, the associated (ear-related consciousness) arises. The arising of these three elements (dhātu) – e.g. ear, sound and ear-consciousness – lead to the percept, known as "contact" and in turn causes a pleasant or unpleasant or neutral "feeling" to arise. It is from such a feeling that "craving" arises. (See Fig. 1.)
In a discourse entitled, "The All" (Sabba Sutta, SN 35.23), The Buddha states that there is no "all" outside of the six pairs of sense bases (that is, six internal and six external sense bases). The "To Be Abandoned Discourse" (Pahanaya Sutta, SN 35.24) further expands the All to include first five aforementioned sextets (internal sense bases, external sense bases, consciousness, contact and feeling). In the famed "Fire Sermon" (Ādittapariyāya Sutta, SN 35.28) The Buddha declares that "the All is aflame" with passion, aversion, delusion and Suffering (Dukkha); to obtain release from this Suffering, one should become disenchanted with the All.
- Viññāṇa arises as a result of the material sense bases (āyatana)
- there are six types of consciousness, each unique to one of the internal sense organs
- consciousness (Viññāṇa) is separate (and arises) from mind (mano)
- here, consciousness cognizes or is aware of its specific Sense base (including the mind and mind objects)
- Viññāṇa is a prerequisite for the arising of craving (taṇhā)
- hence, for the vanquishing of Suffering (Dukkha), one should neither identify with nor attach to Viññāṇa
In Buddhism, consciousness (Viññāṇa) is one of the five classically defined experiential "aggregates" (Pali: khandha; Skt.: Skandha). As illustrated (Fig. 2), the four other aggregates are material "form" (rupa), "feeling" or "sensation" (Vedana), "perception" (sanna), and "volitional formations" or "fabrications" (Sankhara).
- "And why do you call it 'consciousness'? Because it cognizes, thus it is called consciousness. What does it cognize? It cognizes what is sour, bitter, pungent, sweet, alkaline, non-alkaline, salty, & unsalty. Because it cognizes, it is called consciousness."
" "And why do you call it 'perception'? Because it perceives, thus it is called 'perception.' What does it perceive? It perceives blue, it perceives yellow, it perceives red, it perceives white. Because it perceives, it is called perception."
Similarly, in the traditionally venerated 5th c. CE commentary, the Visuddhimagga, there is an extended analogy about a child, an adult villager and an expert "money-changer" seeing a heap of coins; in this analogy, the child's experience is likened to perception, the villager's experience to consciousness, and the money-changer's experience to true understanding (paňňā). Thus, in this context, "consciousness" denotes more than the irreducible subjective experience of sense data suggested in the discourses of "the All" (see prior section); here, "consciousness" additionally entails a depth of awareness reflecting a degree of memory and recognition.
All of the aggregates are to be seen as empty of self-nature; that is, they arise dependent on causes (hetu) and conditions (paticca). In this scheme, the cause for the arising of consciousness (Viññāṇa) is the arising of one of the other aggregates (physical or mental); and, the arising of consciousness in turn gives rise to one or more of the mental (nāma) aggregates. In this way, the chain of causation identified in the aggregate (khandha) model overlaps the chain of conditioning in the Dependent origination (Paticcasamuppāda) model, described more fully below.
Consciousness (Viññāṇa) is the third of the traditionally enumerated Twelve Causes (Nidāna) of Dependent origination (Pali: paṭiccasamuppāda; Skt.: Pratītyasamutpāda). Within the context of Dependent origination, different canonical discourses represent different aspects of consciousness. The following aspects are traditionally highlighted:
- consciousness is conditioned by mental fabrications (Saṅkhāra);
- consciousness and the mind-body (nāmarūpa) are interdependent; and,
- consciousness acts as a "life force" by which there is a continuity across rebirths.
In three discourses in the Samyutta Nikaya, The Buddha highlights three particular manifestations of Saṅkhāra as particularly creating a "basis for the maintenance of consciousness" (ārammaṇaṃ ... viññāṇassa ṭhitiyā) that could lead to future existence, to the perpetuation of bodily and mental processes, and to craving and its resultant Suffering. As stated in the common text below (in English and Pali), these three manifestation are intending, planning and enactments of latent tendencies ("obsessing")
... [W]hat one intends, and what one plans, and whatever one has a tendency towards:
- Bhikkhus, what one intends, and what one plans, and whatever one has a tendency towards: this becomes a basis for the maintenance of consciousness. When there is a basis there is a support for the establishing of consciousness. When consciousness is established and has come to growth, there is the production of future renewed existence. When there is the production of future renewed existence, future birth, aging-and-death, sorrow, lamentation, pain, displeasure, and despair come to be. Such is the origin of this whole mass of Suffering.
The language of the post-canonical Samyutta Nikaya commentary and subcommentary further affirm that this text is discussing the means by which "kammic consciousness" "yield[s] fruit in one's mental continuum." In other words, certain intentional or obsessive acts on one's part inherently establish in present consciousness a basis for future consciousness's existence; in this way, the future existence is conditioned by certain aspects of the initial intention, including its wholesome and unwholesome qualities.
- "... owing to the abandonment of passion, the support is cut off, and there is no base for consciousness. Consciousness, thus unestablished, not proliferating, not performing any function, is released. Owing to its release, it is steady. Owing to its steadiness, it is contented. Owing to its contentment, it is not agitated. Not agitated, he (the Monk) is totally unbound right within. He discerns that 'Birth is ended, the holy life fulfilled, the task done. There is nothing further for this world.'"
- "It is as if two sheaves of reeds were to stand leaning against one another. In the same way, from name-&-form as a requisite condition comes consciousness, from consciousness as a requisite condition comes name-&-form....
- "If one were to pull away one of those sheaves of reeds, the other would fall; if one were to pull away the other, the first one would fall. In the same way, from the cessation of name-&-form comes the cessation of consciousness, from the cessation of consciousness comes the cessation of name-&-form...."
As described above in the discussion of mental fabrications' conditioning of consciousness, past intentional actions establish a kammic seed within consciousness that expresses itself in the future. Through consciousness's "life force" aspect, these future expressions are not only within a single lifespan but propel kammic impulses (kammavega) across samsaric rebirths.
- "... Unsurpassed is the Blessed Lord's way of teaching Dhamma in regard to the attainment of vision.... Here, some ascetic or Brahmin, by means of ardour, endeavour, application, vigilence and due attention, reaches such a level of concentration that he ... comes to know the unbroken stream of human consciousness as established both in this world and in the next...."
- "'From consciousness as a requisite condition comes name-and-form.' Thus it has been said. And this is the way to understand how from consciousness as a requisite condition comes name-and-form. If consciousness were not to descend into the mother's womb, would name-and-form take shape in the womb?"
"If, after descending into the womb, consciousness were to depart, would name-and-form be produced for this world?"
"If the consciousness of the young boy or girl were to be cut off, would name-and-form ripen, grow, and reach maturity?"
"Thus this is a cause, this is a reason, this is an origination, this is a requisite condition for name-and-form, i.e., consciousness."
- (Buddha:) "... Ānanda, Kamma is the field, consciousness the seed and craving the moisture for consciousness of beings hindered by ignorance and fettered by craving to become established in [one of the "three worlds"]. Thus, there is re-becoming in the future."
The Patthana, part of the Theravadin Abhidharma, analyzes the different states of consciousness and their functions. The Theravāda school method is to study every state of consciousness. Using this method, some states of consciousness are identified as positive, some negative and some neutral. This analysis is based on the principle of Karma, the main point in understanding the different consciousness. All together according to the Abhidhamma, there are 89 kinds of consciousness, 54 are of the "sense sphere" (related to the five physical senses as well as craving for sensual pleasure), 15 of the "fine-material sphere" (related to the meditative absorptions based on material objects), 12 of the "immaterial sphere" (related to the immaterial meditative absorptions), and eight are supramundane (related to the realization of Nibbāna).
Viññāṇa has two components: the awareness itself, and the object of that awareness (which might be a perception, a feeling etc.). Thus, in this way, these viññāṇas are not considered as ultimate (underived) phenomena as they are based on Mental factors (Cetasika). For example, jhānic (meditative) states are described as based on the five ultimate Mental factors of applied thought (Vitakka), sustained thought (Vicara), rapture (piti), serenity (Sukha) and one-pointedness (ekaggatā).
According to Bhikkhu Bodhi, the post-canonical Pali commentary uses the three terms Viññāṇa, mano and Citta as synonyms for the mind Sense base (mana-Ayatana); however, in the Sutta Pitaka, these three terms are generally contextualized differently:
- Viññāṇa refers to awareness through a specific internal Sense base, that is, through the eye, ear, nose, tongue, body or mind. Thus, there are six sense-specific types of Viññāṇa. It is also the basis for personal continuity within and across lives.
- Manas refers to mental "actions" (Kamma), as opposed to those actions that are physical or verbal. It is also the sixth internal Sense base (Ayatana), that is, the "mind base," cognizing mental sense (dhammā) as well as sensory information from the physical sense bases.
- Citta includes the formation of thought, emotion and volition; this is thus the subject of Buddhist mental development (Bhava), the mechanism for release.
Across Buddhist schools
- Eye consciousness
- Ear consciousness
- Nose consciousness
- Tongue consciousness
- Body consciousness
- Mind consciousness describe the consciousness of "ideas" - Buddhism describes not five but six perceptions.
- See also: Eight Consciousnesses
- a consciousness called klistamanas, which gathers the hindrances, the poisons, the karmic formations.
- the ālāyavijñāna is the consciousness "basis of everything" and has been translated as "store consciousness". Every consciousness is based on this one. It is the phenomenon which explains the Rebirth.
The amalavijñāna (阿摩羅識), is considered by some Yogācāra's schools as a ninth consciousness. It is the pure state associated with the nirvāna. But some schools considers the amalavijñāna to be the pure aspect of the ālāyavijñāna.
Viññāna is used in Thai Buddhism to refer specifically to one's consciousness or life-force after it has left the body at the moment of death. Thais differentiate between winyaan and "jid-jai" (จิตใจ), which is the consciousness while it is still connected to a living body. Even though the jid-jai leaves the body while you dream at night and can also externalize during advanced meditation practice, it is still connected to the body.
- "He alone who, after reaching the Nitya, the Absolute, can dwell in the Līlā, the :Relative, and again climb from the Līlā to the Nitya, has ripe knowledge and :devotion. Sages like Narada cherished love of God after attaining the Knowledge of :Brahman. This is called vijnāna." Also: "What is Vijnana? It is to know God distinctly by realizing His existence through an intuitive experience and to speak to Him intimately."
