Buddhahood in the context of Kenshō

The English term enlightenment is the Western translation of various Buddhist terms, most notably bodhi and vimutti. The abstract noun bodhi (/ˈboʊdi/; Sanskrit: बोधि; Pali: bodhi) means the knowledge or wisdom, or awakened intellect, of a Buddha. The verbal root budh- means "to awaken", and its literal meaning is closer to awakening. Although the term buddhi is also used in other Indian philosophies and traditions, its most common usage is in the context of Buddhism. Vimutti is the freedom from or release of the fetters and hindrances.

The term enlightenment was popularised in the Western world through the 19th-century translations of British philologist Max Müller. It has the Western connotation of general insight into transcendental truth or reality. The term is also being used to translate several other Buddhist terms and concepts, which are used to denote (initial) insight (prajna (Sanskrit), wu (Chinese), kensho and satori (Japanese)); knowledge (vidya); the "blowing out" (nirvana) of disturbing emotions and desires; and the attainment of supreme Buddhahood (samyak sam bodhi), as exemplified by Gautama Buddha.

Amitābha (Sanskrit pronunciation: [ɐmɪˈtaːbʱɐ], "Measureless" or "Limitless" Light), also known as Amituofo in Chinese, Amida Butsu in Japanese, Amita-bul in Korean, A Di Đà Phật in Vietnamese, and Öpakmé in Tibetan, is one of the main Buddhas of Mahayana Buddhism and the most widely venerated Buddhist figure in East Asian Buddhism. Amitābha is also known by the name Amitāyus ("Measureless Life").

Amitābha is the main figure in two influential Indian Buddhist Mahayana Scriptures: the Sutra of Measureless Life and the Amitābha Sūtra. According to the Sutra of Measureless Life, Amitābha established a pure land of perfect peace and happiness, called Sukhāvatī ("Blissful"), where beings who mindfully remember him with faith may be reborn and then quickly attain enlightenment. The pure land is the result of a set of vows Amitābha made long ago. As his name means Limitless Light, Amitābha's light is said to radiate throughout the cosmos and shine on all beings. Because of this, Amitābha is often depicted radiating light, a symbol for his wisdom. As per the name Amitāyus, this Buddha is also associated with infinite life, since his lifespan is said to be immeasurable. Amitābha's measureless life is seen as being related to his infinite compassion.

In Buddhism, an Arhat (Sanskrit: अर्हत्) or Arahant (Pali: अरहंत्, 𑀅𑀭𑀳𑀦𑁆𑀢𑁆) is one who has gained insight into the nature of existence, has achieved Nirvana, and has been liberated from the endless cycle of rebirth.

The understanding of the concept has changed over the centuries, and varies between different schools of Buddhism and different regions. A range of views on the attainment of arhats existed in the early Buddhist schools. The Sarvāstivāda, Kāśyapīya, Mahāsāṃghika, Ekavyāvahārika, Lokottaravāda, Bahuśrutīya, Prajñaptivāda, and Caitika schools all regarded arhats as imperfect in their attainments compared to buddhas.

In Buddhism, a bodhisattva is a person who has attained, or is striving towards, bodhi ('awakening', 'enlightenment') or Buddhahood. Often, the term specifically refers to a person who forgoes or delays personal nirvana or bodhi in order to compassionately help other individuals reach Buddhahood.

In the Early Buddhist schools, as well as modern Theravāda Buddhism, bodhisattva (or bodhisatta) refers to someone who has made a resolution to become a Buddha and has also received a confirmation or prediction from a living Buddha that this will come to pass. In Theravāda Buddhism, the bodhisattva is mainly seen as an exceptional and rare individual. Only a few select individuals are ultimately able to become bodhisattvas, such as Maitreya.

A Buddhist temple or Buddhist monastery is the place of worship for adherents of Buddhism. They include the structures called vihara, chaitya, stupa, wat, khurul and pagoda in different regions and languages. Temples in Buddhism represent the pure land or pure environment of a Buddha. Traditional Buddhist temples are designed to inspire both inner and outer peace.

Buddhist temples follow a set of architectural guides adhering to Buddhist architecture principal, with stylistic derivatives seen throughout South Asia, Southeast Asia, and East Asia.

Vajrayāna (Sanskrit: वज्रयान, lit. 'Diamond Vehicle or Thunderbolt Vehicle'), otherwise known as Mantrayāna ("Mantra Vehicle"), Guhyamantrayāna ("Secret Mantra Vehicle"), Tantrayāna ("Tantra Vehicle"), Indo-Tibetan Buddhism, Tantric Buddhism, and Esoteric Buddhism, is a Mahāyāna Buddhist tradition that emphasizes esoteric practices and rituals aimed at rapid spiritual awakening. Emerging between the 5th and 7th centuries CE in medieval India, Vajrayāna Buddhism incorporates a range of techniques, including the use of mantras (sacred sounds), dhāraṇīs (mnemonic codes), mudrās (symbolic hand gestures), mandalās (spiritual diagrams), and the visualization of deities and Buddhas. These practices are designed to transform ordinary experiences into spiritual paths toward enlightenment and liberation, often by engaging with aspects of desire and aversion in a ritualized context.

A distinctive feature of Vajrayāna Buddhism is its emphasis on esoteric transmission, where teachings are passed directly from teacher (guru or vajrācārya) to student through initiation ceremonies. Tradition asserts that these teachings have been passed down through an unbroken lineage going back to the historical Buddha (c. the 5th century BCE), sometimes via other Buddhas or bodhisattvas (e.g., Vajrapani). This lineage-based transmission ensures the preservation of the purity and effectiveness of the teachings. Practitioners often engage in deity yoga, a meditative practice where one visualizes oneself as a deity embodying enlightened qualities to transform one's perception of reality. The tradition also acknowledges the role of feminine energy, venerating female Buddhas and ḍākiṇīs (spiritual beings), and sometimes incorporates practices that challenge conventional norms to transcend dualistic thinking.

Buddhism is an ancient Indian religion, which arose in and around the ancient Kingdom of Magadha (now Bihar, India). It is based on the teachings of Gautama Buddha, who lived in the 6th or 5th century BCE and was deemed a "Buddha" or an "Awakened One". Buddhist records in the Theravada tradition list Gautama Buddha as the fourth Buddha of our kalpa, while the next buddha will be Maitreya Buddha. Buddhism spread outside of Northern India beginning in the Buddha's lifetime.

In the 3rd century BCE and during the reign of the Mauryan Emperor Ashoka, the Buddhist community split into two schools: the Mahāsāṃghika and the Sthaviravāda, each of which spread throughout India and grew into numerous sub-schools. In modern times, three major branches of Buddhism exist: the Theravada in Sri Lanka and Southeast Asia, and the Mahayana in the Himalayas and East Asia, and the Vajrayana throughout Asia and specifically in Tibet, Nepal, and Bhutan.

Kenshō (Rōmaji; Japanese and classical Chinese: 見性, Pinyin: jianxing, Sanskrit: dṛṣṭi-svabhāva) is an East Asian Buddhist term from the Chan / Zen tradition which means "seeing" or "perceiving" (見) "nature" or "essence" (性), or 'true face'. It is usually translated as "seeing one's [true] nature," with "nature" referring to buddha-nature, ultimate reality, the Dharmadhatu. The term appears in one of the classic slogans which define Chan Buddhism: to see oneʼs own nature and accomplish Buddhahood (見性成佛).

Kenshō is an initial insight or sudden awakening, not full Buddhahood. It is to be followed by further training which deepens this insight, allows one to learn to express it in daily life and gradually removes the remaining defilements.

Guanyin (Chinese: 觀音; pinyin: Guānyīn; Jyutping: Gun1 jam1) is a common Chinese name of the bodhisattva associated with compassion known as Avalokiteśvara (Sanskrit: अवलोकितेश्वर). Guanyin is short for Guanshiyin, which means "[The One Who] Perceives the Sounds of the World". Originally regarded as male in Indian Buddhism, Guanyin has been more commonly depicted as female in China and most of East Asia since about the 12th century. Due to sociogeographical factors, Guanyin may also be historically depicted as genderless or androgynous. On the 19th day of the sixth lunar month, Guanyin's attainment of Buddhahood is celebrated. Guanyin has been incorporated in other religions, including Taoism and Chinese folk religion.

Some Buddhists believe that when one of their adherents departs from this world, they are placed by Guanyin in the heart of a lotus and then sent to the western pure land of Sukhāvatī. Guanyin is often referred to as the "most widely beloved Buddhist Divinity" with miraculous powers to assist all those who pray to her, as is mentioned in the universal gate chapter of the Lotus Sutra and the Kāraṇḍavyūha Sūtra.

Bon or Bön (Tibetan: བོན་, Wylie: bon, ZWPY: Pön, Lhasa dialect: [pʰø̃̀]), also known as Yungdrung Bon (Tibetan: གཡུང་དྲུང་བོན་, Wylie: gyung drung bon, ZWPY: Yungchung Pön, lit. 'eternal Bon'), is the indigenous Tibetan religion which shares many similarities and influences with Tibetan Buddhism. It initially developed in the tenth and eleventh centuries but retains elements from earlier Tibetan religious traditions. Bon is a significant minority religion in Tibet, especially in the east, as well as in the surrounding Himalayan regions.

The relationship between Bon and Tibetan Buddhism has been a subject of debate. According to the modern scholar Geoffrey Samuel, while Bon is "essentially a variant of Tibetan Buddhism" with many resemblances to Nyingma, it also preserves some genuinely ancient pre-Buddhist elements. David Snellgrove likewise sees Bon as a form of Buddhism, albeit a heterodox kind. Similarly, John Powers writes that "historical evidence indicates that Bön only developed as a self-conscious religious system under the influence of Buddhism".

Vairocana ("The Sun", "Solar" or "Shining" in Sanskrit), also known as Mahāvairocana (Great Sun), is a major Buddha from Mahayana and Vajrayana Buddhism. He is often compared to the Sun, because both bestow their light impartially upon all beings. However, unlike the Sun, whose light can be blocked, and which disappears at night, Vairocana's light is omnipresent, impossible to block, and shines eternally. Hence, he is called the "Great Sun". In East Asian Buddhism, Vairocana is called "大日如來" (Great Sun Thus Come One) or "毘盧遮那佛" (Vairocana Buddha).

In Mahayana and Vajrayana Buddhism, Vairocana is the Dharma-Body of all Buddhas (Dharma-Body is the true body of all Buddhas, equivalent to the Ultimate Reality), which is formless, omnipresent, self-existent, eternal, indestructible, unable to be defiled, and is the source of all manifestations. The historical Gautama Buddha is one of the emanation bodies of Vairocana Buddha.

Honzon (本尊, "fundamental honored [one]"), sometimes referred to as a Gohonzon (ご本尊 or 御本尊), is the enshrined main image or principal deity in Japanese Buddhism. The buddha, bodhisattva, or mandala image is located in either a temple or a household butsudan.

The image can be either a statue or a small scroll and varies from sect to sect. It can be a singular image or a group of images; the honzon in the main (hondō) or treasure (kondō) hall of the temple can be for that particular hall or the entire temple complex. Sometimes honzon is the central image (chūson) of a cluster of three (sanzonbutsu) or five (goson) images.

Bhaiṣajyaguru (Sanskrit: भैषज्यगुरु, Chinese: 藥師佛, Japanese: 薬師仏, Korean: 약사불, Vietnamese: Dược Sư Phật, Standard Tibetan: སངས་རྒྱས་སྨན་བླ), or Bhaishajyaguru, formally Bhaiṣajya-guru-vaiḍūrya-prabha-rāja ("Medicine Master and King of Lapis Lazuli Light"; Chinese: 藥師琉璃光(王)如來, Japanese: 薬師瑠璃光如来, Korean: 약사유리광여래, Vietnamese: Dược Sư Lưu Ly Quang Vương Như Lai), is the Buddha of healing and medicine in Mahāyāna Buddhism. Commonly referred to as the "Medicine Buddha", he is described as a doctor who cures suffering (Pali/Sanskrit: dukkha/duḥkha) using the medicine of his teachings.

The image of Bhaiṣajyaguru is usually expressed with a canonical Buddha-like form holding a gallipot and, in some versions, possessing blue or deep green skin. Though also considered to be a guardian of the East, in most cases, Akshobhya is given that role. As an exceptional case, the honzon of Mount Kōya's Kongōbu Temple was changed from Akshobhya to Bhaiṣajyaguru.

Jōdo Shinshū (浄土真宗, "The True Essence of the Pure Land Teaching"), also known as Shin Buddhism or True Pure Land Buddhism, is a Japanese tradition of Pure Land Buddhism founded by Shinran (1173–1263). Shin Buddhism is the most widely practiced branch of Buddhism in Japan, and its membership is claimed to include 10 percent of all Japanese citizens. The school is based on the Pure Land teachings of Shinran, which are based on those of earlier Pure Land masters Hōnen, Shandao and Tanluan, all of whom emphasized the practice of nembutsu (the recitation of Amida Buddha's name) as the primary means to obtain post-mortem birth in the Pure Land of Sukhavati (and thus, Buddhahood).

Shinran taught that enlightenment cannot be realized through one’s own self-power (jiriki), whether by moral cultivation, meditation, or ritual practice, but only through the other-power (tariki) of Amida Buddha’s compassionate Vow. Therefore, in Shin Buddhism, the nembutsu is not a meritorious deed or practice that produces merit and liberation, but an expression of joyful gratitude for the assurance of rebirth in the Pure Land, which has already been granted by Amida’s inconceivable wisdom and compassion. Doctrinally, Jōdo Shinshū is grounded in Shinran’s magnum opus, the Kyōgyōshinshō (Teaching, Practice, Faith, and Realization), which presents a comprehensive exegesis of Pure Land thought based on Indian and Chinese Mahāyāna sources. Shinran’s synthesis reframes the Pure Land path as the culmination of Mahāyāna Buddhism, emphasizing ideas like true faith (shinjin), other-power, the abandonment of self-power, the nembutsu of gratitude, and the all-embracing compassion of Amida Buddha's Original Vow.

Pure Land is a Mahayana Buddhist concept referring to a transcendent realm emanated by a buddha or bodhisattva which has been purified by their activity and sustaining power. Pure lands are said to be places without the sufferings of samsara and to be beyond the three planes of existence. Many Mahayana Buddhists aspire to be reborn in a Buddha's pure land after death.

The term "Pure Land" is particular to East Asian Buddhism (Chinese: 淨土; pinyin: Jìngtǔ). In Sanskrit Buddhist sources, the equivalent concept is called a buddha-field (buddhakṣetra) or more technically a pure buddha-field (viśuddha-buddhakṣetra). It is also known by the Sanskrit term buddhabhūmi (Buddha land). In Tibetan Buddhism meanwhile, the term "pure realms" (Tibetan: དག་པའི་ཞིང Wylie: dag pa'i zhing) is also used as a synonym for buddhafield.

The Nianfo (Chinese: 念佛; pinyin: niànfó, alternatively in Japanese 念仏 (ねんぶつ, nenbutsu); Korean: 염불; RR: yeombul; or Vietnamese: niệm Phật) is a Buddhist practice central to East Asian Buddhism. The Chinese term nianfo is a translation of Sanskrit buddhānusmṛti ("recollection of the Buddha"), a classic Buddhist mindfulness (smṛti) practice.

Nianfo focused on the Buddha Amitābha is also the most important practice in Pure Land Buddhism. In the context of East Asian Pure Land practice, nianfo typically refers to the oral repetition of the name of Amitābha through the phrase "Homage to Amitabha Buddha" (Ch: 南無阿彌陀佛, Mandarin: Nāmó Āmítuófó, Jp: Namu Amida Butsu, Vn: Nam-mô A-di-đà Phật; from the Sanskrit: Namo'mitābhāya Buddhāya). It can also refer to that phrase itself, in which case it may also be called the nianfo, or "The Name" (Japanese: myōgō 名号).

Mahayana is the largest branch of Buddhism, followed by Theravada. It is a broad group of Buddhist traditions, texts, philosophies, and practices developed in ancient India (c. 1st century BCE onwards). Mahāyāna accepts the main scriptures and teachings of early Buddhism but also recognizes various doctrines and texts that are not accepted by Theravada Buddhism as original. These include the Mahāyāna sūtras and their emphasis on the bodhisattva path and Prajñāpāramitā. Vajrayana or Mantra traditions are a subset of Mahāyāna which makes use of numerous Tantric methods Vajrayānists consider to help achieve Buddhahood.

Mahāyāna also refers to the path of the bodhisattva striving to become a fully awakened Buddha for the benefit of all sentient beings, and is thus also called the "Bodhisattva Vehicle" (Bodhisattvayāna). Mahāyāna Buddhism generally sees the goal of becoming a Buddha through the bodhisattva path as being available to all and sees the state of the arhat as incomplete. Mahāyāna also includes numerous Buddhas and bodhisattvas that are not found in Theravada (such as Amitābha and Vairocana). Mahāyāna Buddhist philosophy also promotes unique theories, such as the Madhyamaka theory of emptiness (śūnyatā), the Vijñānavāda ("the doctrine of consciousness" also called "mind-only"), and the Buddha-nature teaching.

The Mahāsāṃghika (Brahmi: 𑀫𑀳𑀸𑀲𑀸𑀁𑀖𑀺𑀓, "of the Great Sangha", Chinese: 大眾部; pinyin: Dà zhòng bù; Vietnamese: Đại chúng bộ) was a major division (Nikāya) of the early Buddhist schools in India. They were one of the two original communities that emerged from the first schism of the original pre-sectarian Buddhist tradition (the other being the Sthavira Nikāya). This schism is traditionally held to have occurred after the Second Buddhist council, which occurred at some point during or after the reign of Kalashoka. The Mahāsāṃghika Nikāya developed into numerous sects which spread throughout ancient India.

Some scholars think that the Mahāsāṃghika Vinaya (monastic rule) represents the oldest Buddhist monastic source, although some other scholars think that it is not the case. While the Mahāsāṃghika tradition is no longer in existence, many scholars look to the Mahāsāṃghika tradition as an early source for some ideas that were later adopted by Mahāyāna Buddhism. Some of these ideas include the view that the Buddha was a fully transcendent being (term "lokottaravāda", "transcendentalism"), the idea that there are many contemporaneous buddhas and bodhisattvas throughout the universe, the doctrine of the inherent purity and luminosity of the mind (Skt: prakṛtiś ćittasya prabhāsvarā), the doctrine of reflexive awareness (svasaṃvedana) and the doctrine of prajñapti-matra (absolute nominalism or pure conceptualism).
