Kensho or Kenshō (見性) is a Japanese term from the Zen tradition. Ken means “seeing”, shō means nature, essence“. It is usually translated as “seeing one’s (true) nature”, that is, the Buddha-nature or nature of mind.

Kenshō is an initial insight or awakening, not full Buddhahood. It is to be followed by further training to deepen this insight, and learn to express it in daily life.

The term kenshō is often used interchangeably with satori, which is derived from the verb satoru, and means “comprehension; understanding”.

The Chinese Buddhist term jianxing (见性; 見性; jiànxìng; chien-hsing) compounds:

  • jian 見 “see, observe, meet with, perceive”;
  • xing 性 “(inborn) nature, character, personality, disposition, property, quality, gender”.


Buddhist monks who produced Sanskrit-Chinese translations of sutras faced many linguistic difficulties:

  • They chose Chinese jian 見 to translate Sanskrit dṛś दृश् “see, look”, and the central Buddhist idea of dṛṣṭi दृष्टि “view, seeing (also with the mind’s eye), wisdom, false view”.
  • Translators used xing 性 or zixing 自性 “self-nature” for Sanskrit svabhāva स्वभाव “intrinsic nature, essential nature”.

Thus, jianxing was the translation for dṛṣṭi-svabhāva, “view one’s essential nature”.

The (c. 8th century) Chinese Platform Sutra (2, Prajñā “wisdom, understanding”) first records jianxing.


The Standard Chinese pronunciation jianxing historically derives from (c. 7th century CE) Middle Chinese kienCsjäŋC. Sino-Xenic pronunciations of this term exist:

  • kenshō 見性 or ケンショウ (on’yomi) in Sino-Japanese vocabulary
  • Korean: 견성; RR: gyeonseong in Sino-Korean vocabulary
  • kiến tính in Sino-Vietnamese vocabulary.

Translating kenshō into English is semantically complex.

Encyclopedic and dictionary definitions

Some encyclopedia and dictionary definitions are:

  • Soothill (1934): “To behold the Buddha-nature within oneself, a common saying of the Chan (Zen) or Intuitive School.”
  • Fischer-Schreiber (1991): Lit. “seeing nature”; Zen expression for the experience of awakening (enlightenment). Since the meaning is “seeing one’s own true nature,” kenshō is usually translated “self-realization.” Like all words that try to reduce the conceptually ungraspable experience of enlightenment to a concept, this one is also not entirely accurate and is even misleading, since the experience contains no duality of “seer” and “seen” because there is no “nature of self’ as an object that is seen by a subject separate from it.
  • Baroni (2002): “Seeing one’s nature,” that is, realizing one’s own original Buddha Nature. In the Rinzai school, it most often refers more specifically to one’s initial enlightenment attained through kōan practice.
  • Muller (year unknown): To see one’s own originally enlightened mind. To behold the Buddha-nature within oneself, a common saying of the Chan school, as seen for example, in the phrase ‘seeing one’s nature, becoming Buddha’ 見性成佛.

Definitions by Buddhist scholars

Buddhist scholars have defined kenshō as:

  • D.T. Suzuki: “Looking into one’s nature or the opening of satori”; “This acquiring of a new point of view in our dealings with life and the world is popularly called by Japanese Zen students ‘satori’ (wu in Chinese). It is really another name for Enlightenment (Annuttara-samyak-sambodhi)”.
  • Dumoulin (1988/2005): “Enlightenment is described here as an insight into the identity of one’s own nature with all of reality in an eternal now, as a vision that removes all distinctions. This enlightenment is the center and the goal of the Zen way. Hakuin prefers the term “seeing into one’s nature”, which for him means ultimate reality. The Buddha nature and the cosmic Buddha body, wisdom (prajna), and emptiness (sunyata), the original countenance one had before one was born, and other expressions from the rich palette of Mahayana terms were all familiar to him from his continued study of the sutras and Zen literature.”
  • Peter Harvey (1990): “It is a blissful realization where a person’s inner nature, the originally pure mind, is directly known as an illuminating emptiness, a thusness which is dynamic and immanent in the world.”
  • G. Victor Sogen Hori (2000): “The term consists of two characters: ken, which means “see” or “seeing”, and sho, which means “nature”, “character”, “quality.” To “see one’s nature” is the usual translation for kensho“.

Definitions by Buddhist teachers and practitioners

Buddhist teachers and practitioners have defined kenshō as:

  • Jiyu-Kennett: “To see into one’s own nature. The experience of enlightenment, satori.”
  • Myodo Ni Satomi, a student of Hakuun Yasutani (1993): “Seeing the-self, that is, the true self or Buddha nature.”

According to Hori, the term kenshō refers to the realization of non-duality of subject and object in general, but the term kenshō may also be applied in other contexts: “How do you kenshō this?”

Kenshō is not a single experience, but refers to a whole series of realizations from a beginner’s shallow glimpse of the nature of mind, up to a vision of emptiness equivalent to the ‘Path of Seeing’ or to Buddhahood itself. In all of these, the same ‘thing’ is known, but in different degrees of clarity and profundity.

“Kenshō” is commonly translated as enlightenment, a word that is also used to translate bodhi, prajna, satori and buddhahood. Western discourse tends to use these terms interchangeably, but there is a distinction between a first insight and the further development toward Buddhahood.

Insight versus experience

See also: Buddhist modernismTranscendentalism, and Perennial philosophy

Kensho is insight, an understanding of our essential nature as Buddha-nature, or the nature of mind, the perceiving subject itself, which was equated with Buddha-nature by the East Mountain school.

Contemporary understanding also describes kensho as an experience, as in “enlightenment experience”; the term “enlightenment experience” is itself a tautology: “Kensho (enlightenment) is an enlightenment (kensho)-experience”. The notion of “experience” fits in a popular set of dichotomies: pure (unmediated) versus mediated, noncognitive versus cognitive, experiential versus intellectual, intuitive versus intellectual, nonrational versus rational, nondiscursive versus discursive, nonpropositional versus propositional.

The notion of pure experience (junsui kuiken) to interpret and understand kensho was introduced by Nishida Kitaro in his An Inquiry into the Good (1911), under influence of “his somewhat idiosyncratic reading of western philosophy”, especially William James, who wrote The Varieties of Religious Experience. Wayne Proudfoot traces the roots of the notion of “religious experience” to the German theologian Friedrich Schleiermacher (1768-1834), who argued that religion is based on a feeling of the infinite. The notion of “religious experience” was used by Schleiermacher to defend religion against the growing scientific and secular critique. It was adopted by many scholars of religion, of which William James was the most influential. D.T. Suzuki, who introduced Nishida Kitaro to western philosophy, took over this notion of pure experience, describing it as the essence of all religions, but best represented in the superior Japanese culture and religion.

The influence of western psychology and philosophy on Japanese Buddhism was due to the persecution of Buddhism at the beginning of the Meiji Restoration, and the subsequent efforts to construct a New Buddhism (shin bukkyo), adapted to the modern times. It was this New Buddhism which has shaped the understanding of Zen in the west, especially through the writings of D.T. Suzuki and the Sanbo Kyodan, an exponent of the Meiji-era opening of Zen-training for lay-followers.

The notion of “experience” has been criticised. Robert Sharf points out that “experience” is a typical western term, which has found its way into Asian religiosity via western influences. The notion of “experience” introduces a false notion of duality between “experiencer” and “experienced”, where-as the essence of kensho is the realisation of the “non-duality” of observer and observed. “Pure experience” does not exist; all experience is mediated by intellectual and cognitive activity. The specific teachings and practices of a specific tradition may even determine what “experience” someone has, which means that this “experience” is not the proof of the teaching, but a result of the teaching. A pure consciousness without concepts, reached by “cleaning the doors of perception”, would be an overwhelming chaos of sensory input without coherence. The notion of “experience” also over-emphasises kensho, as if it were the single goal of Zen-training, where-as the Zen-tradition clearly states that “the stink of Zen” has to be removed and the “experience” of kensho has to be integrated into daily life. In the Rinzai-school this post-satori training includes the study and mastering of great amounts of classical Chinese poetry, which is far from “universal” and culture-transcending. On the contrary, it demands an education in culture-specific language and behaviour, which is measured by specific and strict cultural norms. Emphasising “experience” “reduces the sophisticated dialectic of Ch’an/Zen doctrine and praxis to a mere “means” or set of techniques intended to inculcate such experiences”.

Kenshō accounts

Classical accounts

Classical Zen texts, such as the Kao-seng-chuan (Biographies of Eminent Monks) and the transmission lists, called “Transmission of the Lamp” the yü-lü genre (the recorded sayings of the masters, such as the Linji yü lü); and the various koan-collections, contain accounts of “enlightenment experiences”. These accounts are not verbatim recordings of such “experiences”, but well-edited texts, written down decades or even decennia after the supposed sayings and meetings.

The Denkōroku, “The Record of the Transmission of the Light”, written by Keizan Jōkin 瑩山紹瑾 (1268–1325), is an example of the “Transmission of the Lamp” genre. It contains literary accounts of the patriarchs of the Soto-lineage, from Shakyamuni Buddha to Koun Ejō, in which kensho plays a central role. They are not to be taken as literal accounts of awakening, but as stories underpinning the legitimacy of the Dogen-shu, which in its early history had seen a fierce internal conflict over the correct lineage during the Sandai sōron.

Dōgen Zenji‘s awakening is recalled in the Denkoroku:

Once, during late-night zazen, Rujing told the monks, “Studying Zen is the dropping off of body and mind.” Hearing this, the master was suddenly greatly awakened. He went at once to the Abbott’s room and burned incense. Rujing asked him, “Why are you burning incense?” The master answered, “Body and mind have dropped off.” Rujing said, “Body and mind have dropped off, the dropped-off body and mind.” The master said, “This is a temporarily ability; you must not approve me without reason.” Rujing replied, “I am not approving you without reason.” The master asked, “Why are you not approving me without reason?” Rujing said, “You dropped off body and mind.” The master bowed. Rujing said, “You have dropped off dropping off.”

Hakuin gives this description of his first kensho, when he was 21:

At around midnight on the seventh and final night of my practice, the boom of a bell from a distant temple reached my ears: suddenly, my body and mind dropped completely away. I rose clear of even the finest dust. Overwhelmed with joy, I hollered out at the tops of my lungs, “Old Yen-t’ou is alive and well! […] After that, however, I became extremely proud and arrogant”.

Hakuin’s kensho was not approved by Shoju Rojin, who subjected Hakuin to more koan-training. This resulted in a second kensho, where-after Hakuin left Shoju Rojin. It was only when he was 41 that he attained “his final great enlightenment”:

[W]hen Shoju had asked his reason for becoming a monk, his reply – that he had done it because he was afraid of falling into hell – had brought the scornful retort: “You’re a self-centered rascal, aren’t you!” Not until eighteen years later, upon attainment of his final great enlightenment at the age of forty-one, would Hakuin fully grasp the significance of Shoju’s reproach and with it the true meaning of “post-satori” practice. Years later, when Hakuin asked his student Tōrei the same question, Tōrei’s answer – “To work for the salvation of my fellow beings” – brought a laugh from Hakuin. “A much better reason than mine”, he said.

Contemporary accounts

Although the Zen tradition is reluctant to speak openly about the ‘experience’ of kensho, personal accounts can be found in Zen texts. Keido Fukushima, a 20th-century Rinzai abbott, gives the following description:

At Nanzenji there is a small hill. I used to walk near there, look at it, and often smile at the high school students who walked by there as well. One day as I walked by, I looked at the hill and it was truly amazing. i was totally lost as if there was no ‘me’. I stood gazing at the hill. Some students walked by and one of them said something like ‘look at that crazy monk’. Finally I came out of it. Life was never the same for me. I was free.

Spontaneous kenshō

Kenshō may be attained without the aid of a teacher. For example, Richard Clarke (1933), who studied with Philip Kapleau, states that he had a spontaneous kensho when he was 13. Dennis Genpo Merzel states he had what he described as an “awakening experience” in 1971:

It was in February of that year, and I was 26 years old. My second serious relationship was ending, and I was feeling very confined and conflicted. I needed to get some space, so I went out to the Mojave desert for a three-day camping weekend with two friends. On the Friday, I hiked up a mountain alone. I knew nothing about meditation or spiritual practice. I was just sitting there, thinking about my life and the things going on. I felt I had gotten pretty screwed up for such a young age.

I could see my VW camper, my home for the weekend, parked a few miles away, . But at the same time, I was aware that my home was back in Long Beach, California. And a natural koan came to me: Where is home? All of a sudden, I had a kind of breakthrough. I felt myself fall away, and I became one with the cosmos, one with the universe, one with all things. I knew in that moment that wherever I am, that is home; home is everywhere. I also knew who I was, beyond description, but let’s call it Big Mind.

That experience completely changed my life.

More descriptions of “spontaneous kensho” can be found throughout the Zen-literature,

Alternate accounts

Houn Jiyu-Kennett, a 20th-century Soto Zen Oshō, i.e. “priest” or “teacher,” and the first Western female Zen priest, had a prolonged religious experience in the 1970s, including a series of visions and recalling past lives, when she was severely ill. She regarded these experiences as “a profound kensho (enlightenment) experience,” constituting a third kensho, and published an account of these visions, and an elaborate scheme of stages of awakening, in How to Grow a Lotus Blossom. Her interpretations, which parallel Christian mysticism, were controversial, and rejected by some as makyo (“illusion”). According to Jiyu-Kennett, such experiences are not uncommon, but are rarely spoken of; she regarded publishing her own experiences as a way to acknowledge the existence and validity of such experiences, which, according to her, may contribute to further insight after initial awakening. She acknowledged the risks and potential for controversy in publishing her account, but felt that the benefits of releasing such information outweighed the risks.

Training towards kenshō

See also: Zen practice

According to Harris, working towards kensho is usually a lengthy process stretched out over years or even decades. Contrary to this, Victor Hori notes that with koan-study kensho may appear within six months.

Sōtō tends towards a gradual approach, preferring to let the experiences happen on their own. Rinzai tends toward the use of Koans as a technique to unroot the habitual workings of the mind.

During intensive zazen various hallucinations and psychological disturbances may arise. These are referred to as makyo. Distinguishing these delusions from actual kensho is the primary function of the teacher, as the student may be erroneously convinced they have realized kensho.


In the Rinzai school, kensho is seen as indispensable:

At some point in time we pass from imprisonment in ignorance and delusion to a true vision of Zen realization: “Our enlightenment is timeless, yet our realization of it occurs in time.” According to this belief experiencing a moment of awakening in this life is of central importance.

In the Rinzai-training, the student is expected to pour oneself totally into both koan-study and daily activities ‘to become one’ with it. Kenshō is used to describe the first breakthrough in kōan study.


Contemporary Japanese Sōtō downplays the importance of kenshō, due to the sectarian rivalry with Rinzai, which emphasizes kenshō. Nevertheless, kenshō also has its role in Sōtō. The “genjo-koan”, or the “koan of everyday life” which “appears naturally in daily life”, is emphasized. Students are not encouraged to actively seek out kenshō experiences. In Sōtō practice kenshōs “are allowed to occur naturally, as a by-product of practice. Meditative training is seen as the unfolding of one great kenshō:

According to the tradition of Soto Zen, although working on a koan is one way of attaining kensho, the best way is zazen. Indeed, Dogen, the founder of Soto Zen, expounded that zazen itself is enlightenment, and as long as the adept maintains a pure state of non-thinking in Zen, he is a Buddha.

According to Brad Warner, in the Sōtō school there are two kinds of awakening. One is the practice of shikantaza, which is the “actual enlightened activity of the Buddha”. The other is the accumulation of little bits of understanding, which come together, giving way to a deeper intuitive knowledge.

Sanbō Kyōdan

Kenshō also plays a central in the Sanbō Kyōdan, a Japanese Zen organisation which played a decisive role in the transmission of Zen to the United States. Yasutani, the founder of the Sanbo Kyodan, was disappointed about the lack of interest in kensho in the Soto school. Yasutani’s emphasis on koan training and the importance of kensho was transmitted to his American students:

He was especially vocal concerning the point of kenshō, seeing one’s true nature. He spoke more openly about it then anyone of his times, going so far as to have a public acknowledgement of those who had experienced kensho in a post-sesshin ceremony of bowing in gratitude to the three treasures.

It is also reflected in the inclusion of a relative great amount of kensho stories in “The Three Pillars of Zen”, written by Philip Kapleau, a student of Yasutani.

Training after kenshō

See also: Sahaja

After kensho, further practice is needed to attain a natural, effortless, down-to-earth state of being, the “ultimate liberation”, “knowing without any kind of defilement”.

Further practice

See also: Ten Bulls

Zen Buddhist training does not end with kenshō. Practice is to be continued to deepen the insight and to express it in daily life. According to the contemporary Chan Master Sheng Yen:

Ch’an expressions refer to enlightenment as “seeing your self-nature”. But even this is not enough. After seeing your self-nature, you need to deepen your experience even further and bring it into maturation. You should have enlightenment experience again and again and support them with continuous practice. Even though Ch’an says that at the time of enlightenment, your outlook is the same as of the Buddha, you are not yet a full Buddha.

And the Soto Zen Master Jiyu-Kennett:

One can easily get the impression that realization, kenshō, an experience of enlightenment, or however you wish to phrase it, is the end of Zen training. It is not. It is, rather, a new beginning, an entrance into a more mature phase of Buddhist training. To take it as an ending, and to “dine out” on such an experience without doing the training that will deepen and extend it, is one of the greatest tragedies of which I know. There must be continuous development, otherwise you will be as a wooden statue sitting upon a plinth to be dusted, and the life of Buddha will not increase.

To deepen the initial insight of kensho, shikantaza and kōan-study are necessary. This trajectory of initial insight followed by a gradual deepening and ripening is expressed by Linji Yixuan in his Three mysterious Gates, the Four Ways of Knowing of Hakuin, and the Ten Ox-Herding Pictures which detail the steps on the Path.

Seitai choyo

Post-awakening practice is called seitai choyo, the “long nurturing of the sacred fetus”. According to Spiegelberg,

[I]t means a return to the purely secular life, a complete submersion in work and in the changing events of the world. Thus, for decades, many Zenists, after their awakening, went among the people, living among beggars and leading an existence of hard physical labor. Thus it was proved whether or not the truth received was of permanent value, or whether it would vanish among mundane affairs.

During the T’ang-era, the term became associated with the ideal of the recluse who leaves the world. An ideal period of “twenty years” was taken for it, echoing a story from the Lotus Sutra about a prodigal son who wandered in poverty for twenty years before returning home. References to these twenty years are found throughout the Chán-tradition, for example Linji, who is reported to have studied under Huang-po for twenty years, and Daito, the founder of Daitoku-ji, who famously spent twenty years living under a bridge with beggars.

Cultivating bodhicitta

According to Hakuin, the main aim of “post-satori practice” (gogo no shugyo or kojo, “going beyond”) is to cultivate the “Mind of Enlightenment”, “benefiting others by giving them the gift of the Dharma teaching”. According to Yamada Koun, “if you cannot weep with a person who is crying, there is no kensho”. According to Kay,

The intuitive realisation of Buddhahood requires an attitude of selflessness and faith in one’s inherent enlightenment. Meditative awakening, or wisdom, forms only part of this realisation that must also manifest itself through acts of compassion and love.

According to Barry, regarding Hakuin’s practice after awakening,

Post-satori practice for Hakuin meant finally ceasing to be preoccupied with his own personal condition and attainment and to devote himself and his practice to helping and teaching others. Finally, at long last, he realized that true enlightenment is a matter of endless practice and compassionate functioning, not something that occurs once and for all in one great moment on the cushion.

Self-purification and intellectual understanding

One also has to purify oneself by ongoing practice, since

Kensho does not eradicate our unhealthy habits […] There is a sudden awakening to the fact of “no-self” and then this insight has to be integrated into one’s life which means that it has to be embodied and not just be a memory.

And “experience” has to be supplemented by intellectual understanding and study of the Buddhist teachings;  otherwise one remains a zen temma, a “Zen devil“.

Sudden insight

Main article: Subitism

Kenshō is described as appearing suddenly, upon an interaction with someone else, at hearing or reading some significant phrase, or at the perceiving of an unexpected sound or sight. The idea of “sudden insight” has been hotly debated in the history of Zen. It became part of the Traditional Zen Narrative in the 8th century.

Chinul, a 12th-century Korean Seon master, emphasized that insight into our true nature is sudden, but is to be followed by practice to ripen the insight and attain full Buddhahood. The contemporary Korean Seon master Seongcheol opposed this, emphasizing “sudden enlightenment, sudden cultivation”. But Jiyu-Kennett, a contemporary western teacher, warns that attaining kenshō does not mean that a person is free from morality, the laws of karma, or the consequences of ones actions. This warning is reflected in the Wild fox koan.

Mushi-dokugo and mushi-dokkaku

Kenshō may be attained without the aid of a teacher, as in the case of mushi-dokugo or (mushi-)dokkaku, a self-awakened pratyeka-buddha.

Though the literal meaning is self-awakened or awakened on one’s own, the emphasis in Zen, when using these terms, lies in the ultimate reliance on one’s own insight, instead of the authority of a teacher:

It is awakening that is one’s true master. With Shakyamuni, the awakening was his master. In other words, the awakened self is one’s master. Apart from getting awakened to that master, there is no awakening. Here practitioner and master are of one body, not two. Instead of having another verify or confirm one’s awakening, one does so for oneself. Of course in this case the self that is verified and the master who does verification are undivided. In their being completely identical is the autonomous, independent, or ultimate nature of the authenticity.

Similarities with other traditions

While the Japanese term “kenshō” is generally used by practitioners of Zen Buddhism, the insight it refers to is not limited to Japanese Zen Buddhism, or even to Buddhism in general.


Main articles: TheravadaVipassana, and Vipassana movement

The Theravada tradition, which is best known in the west through the modern Vipassana movement, discerns four stages of enlightenment, in which Nirvana is being reached in four succeeding sudden steps of insight.


An analogy given by Dzogchen masters is that one’s nature is like a mirror which reflects with complete openness, but is not affected by the reflections. Rigpa is the knowledge that ensues from recognizing this mirror-like clarity, which cannot be found by searching nor identified. One knows that there is a primordial freedom from grasping his or her mind.

Advaita Vedanta

Main articles: Advaita Vedanta and Neo-Advaita

In Advaita Vedanta moksha is attained by jnana, insight-knowledge. In Shankara’s philosophical synthesis insight samadhi is used as a subsidiary to this goal. Swami Vivekananda emphasized the experience of nirvikalpa samadhi as a means to validate religious, transcendental knowledge.
