Vijñāna

• 1. Introduction

  ›

  Vijñana is a word that carries the weight of at least three thousand years of thinking about the mind. Written as vijñāna in Sanskrit or viññāna in Pali, it refuses easy translation. Scholars have rendered it as "consciousness," "life force," "mind," "understanding," "intelligence," and "discernment" -- and none of those words alone captures what the tradition means by it. How can a single term point toward so many different ideas? And what does its persistence across Hinduism, Buddhism, and Thai popular practice tell us about the questions human beings keep returning to: What is the mind? Does it survive death? And what is the difference between simply perceiving the world and truly knowing it?

  The Rig Veda already contains the verbal root that gives vijñana its shape: to distinguish, to discern, to observe, to investigate. By the time of the early Upanishads, vijñana had settled into a range of meanings covering understanding, knowledge, and intelligence. The Sanskrit scholar V.S. Apte, working from a dictionary first published in 1890 and revised through 1957-59, counted at least nine distinct senses for vijñanam: wisdom, discernment, skill, proficiency, worldly knowledge gained from experience, business, music, knowledge of the fourteen lores, and the organ of knowledge itself. Monier Williams, whose dictionary appeared in 1899, traced the root through the Rig Veda, the Katha Upanishad, the Chandogya Upanishad, the Mahabharata, and the Panchatantra, finding everywhere the same cluster of meanings: to recognize, to understand, to become wise, to explain and declare. In the Bhagavad Gita, the entire seventh chapter is devoted to unpacking the distinction between jna -- knowledge of Brahma or the Supreme Spirit -- and vijnana, which Apte marks as its opposite: knowledge derived from worldly experience. Sri Ramakrishna drew this boundary sharply. He described vijnana as the state in which a person, after reaching the Absolute, returns to engage with the relative world -- and then climbs back again. "He alone who, after reaching the Nitya, the Absolute, can dwell in the Lila, the Relative, and again climb from the Lila to the Nitya, has ripe knowledge and devotion," Ramakrishna said. Ayon Maharaj, also known as Swami Medhananda, called this view "Vijnana Vedanta" in his 2018 book Infinite Paths to Infinite Reality, identifying six major tenets -- among them the notion that the vijnani "returns from the state of nirvikalpa samadhi and attains the richer, world-affirming nondual realization that God has become everything."

• 3. Three Contexts in Pali

  ›

  In the Pali Canon's Sutta Pitaka, vinnana shows up in at least three distinct technical contexts, and keeping them separate is essential for understanding Buddhist thought. The first is as a derivative of the sense bases. Buddhism counts six sense bases rather than five: eye, ear, nose, tongue, body, and mind. When one of those internal sense organs and its corresponding external object are both present -- say, an ear and a sound -- a corresponding class of consciousness arises. The Buddha laid this out in the Sabba Sutta (SN 35.23), the "Discourse on the All," declaring that there is no "all" outside the six pairs of sense bases. The Adittyapariyaya Sutta (SN 35.28), known as the Fire Sermon, extends the point: "the All is aflame" with passion, aversion, delusion, and suffering, and release requires becoming disenchanted with it. The second context is vinnana as one of the five aggregates, the khandhas. The other four are material form (rupa), feeling or sensation (vedana), perception (sanna), and volitional formations (sankhara). In SN 22.79, the Buddha distinguishes consciousness from perception by asking what each one does. Perception perceives blue, yellow, red, and white. Consciousness cognizes something more refined: what is sour, bitter, pungent, sweet, alkaline, salty. A 5th-century CE commentary, the Visuddhimagga, makes the distinction concrete through an analogy involving three figures who see a heap of coins: a child's experience represents perception, an adult villager's experience represents consciousness, and an expert money-changer's experience represents true understanding, or panna. The third context is Dependent Origination -- paticcasamuppada -- where vinnana is the third of the twelve causes, conditioned by mental fabrications and in turn conditioning the arising of mind-and-matter, or namarupa.

  The relationship between consciousness, kamma, and rebirth is one of the most carefully worked passages in early Buddhist literature. Three discourses in the Samyutta Nikaya identify three particular mental acts that create what the texts call "a basis for the maintenance of consciousness": intending, planning, and enacting latent tendencies, rendered as "obsessing." The Cetana Sutta (SN 12.38), the Intention Discourse, spells out what this basis produces: "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." Post-canonical Samyutta Nikaya commentaries describe this as "kammic consciousness" yielding fruit in one's mental continuum. But the reverse path is equally documented. In the Upaya Sutta (SN 22.53), the Attached Discourse, the text states that when passion for the five aggregates is abandoned, "the support is cut off, and there is no base for consciousness. Consciousness, thus unestablished, not proliferating, not performing any function, is released." The released monk is described as discerning: "Birth is ended, the holy life fulfilled, the task done. There is nothing further for this world." An Anguttara Nikaya discourse supplies the most compact image for how this cycle operates: kamma is the field, consciousness is the seed, and craving is the moisture. All three must be present for rebirth to take root.

• 5. Two Sheaves of Reeds

  ›

  Ven. Sariputta, in the Nalakalapiyo Sutta (SN 12.67), offered what may be the most elegant image in all of Buddhist philosophy for the relationship between consciousness and the mind-body complex. He described two sheaves of reeds leaning against each other: pull one away and the other falls. "From mind and matter as a requisite condition comes consciousness," he said, "from consciousness as a requisite condition comes mind and matter." Neither has independent existence; each requires the other. The Mahanidana Sutta (DN 15), the Great Causes Discourse, sharpens this into a dialogue between the Buddha and Ven. Ananda about what would happen if consciousness did not descend into the mother's womb -- namarupa would not take shape. If consciousness departed after descending -- namarupa would not be produced. If the consciousness of a young child were cut off -- namarupa would not ripen, grow, or reach maturity. The text is careful to describe this not as a permanent self that migrates, but as an animating phenomenon. Ven. Sariputta, in the Sampasadaniya Sutta (DN 28), the Serene Faith Discourse, called it a "stream of consciousness" -- vinnana-sota -- that spans multiple lives, knowable to one who has reached sufficient concentration to "come to know the unbroken stream of human consciousness as established both in this world and in the next."

  The Abhidhamma literature, and especially the Patthana, part of the Theravadin Abhidharma, took the analysis of consciousness further than any earlier text. Rather than treating vinnana as a single thing, the Abhidhamma breaks it into 89 distinct states, each categorized by its karmic quality. Fifty-four of these states belong to the "sense sphere" -- consciousness related to the five physical senses and to craving for sensual pleasure. Fifteen belong to the "fine-material sphere," arising during meditative absorptions based on material objects. Twelve belong to the "immaterial sphere," associated with immaterial meditative states. Eight are supramundane, tied to the direct realization of Nibbana. At the most granular level, the Abhidhamma defines a single vinnana as a single moment of conceptual consciousness. Ordinary mental activity, in this view, consists of a continual succession of such moments. Each vinnana has two components: the awareness itself and the object of that awareness, whether a perception, a feeling, or something else. The Abhidhamma also describes the jhanic, or meditative, states as resting on five ultimate mental factors: applied thought (vitakka), sustained thought (vicara), rapture (piti), serenity (sukha), and one-pointedness (ekaggatā). According to Bhikkhu Bodhi, the post-canonical Pali commentary uses vinnana, manas, and citta as synonyms for the mind sense base, but in the Sutta Pitaka these three terms are contextualized differently. Citta covers the formation of thought, emotion, and volition, and it is described as "luminous" in A.I.8-10.

• 7. Eight and Nine

  While the Pali traditions settled on six modes of consciousness -- one for each sense base -- some later Buddhist schools went further. The Yogacara, also called the Cittamatra school, added two more. The first, klistamanas, gathers the hindrances, the poisons, and the karmic formations. The second is the alayavijnana, translated as "store consciousness" and described as the consciousness that is the "basis of everything." Every other mode of consciousness is based on this one, and it is the mechanism that explains rebirth in Yogacara thought. Walpola Rahula argued that this store consciousness exists in the early texts as well, identified there as the citta. A further step was taken by some Yogacara schools, which recognized a ninth level: the amalavijnana, or "immaculate consciousness." This pure consciousness is identified with the nature of reality, termed parinispanna, or Suchness. Some interpreters treat it as a distinct level; others consider it the pure aspect of the alayavijnana. Beyond the eightfold and ninefold systems, some Buddhist thinkers have proposed hrdaya, or Heart, consciousness, an eleven-consciousnesses theory, and even an infinity consciousness. In Thai Buddhism today, vinnana specifically refers to the consciousness or life-force after it has left the body at death. Thais distinguish this from "jid-jai," the consciousness still connected to a living body -- a distinction that preserves, in everyday usage, the same question about animating force and continuity that the Mahanidana Sutta posed in the Buddha's dialogue with Ananda.
