East Asian Buddhism in the context of "Pure Land"

The Sinosphere, also known as the Chinese cultural sphere, East Asian cultural sphere, or the Sinic world, encompasses multiple countries in East Asia and Southeast Asia that were historically heavily influenced by Chinese culture. The Sinosphere comprises Greater China, Japan, Korea, Vietnam and historically the Ryukyuans. Other definitions may include the regions of modern-day Mongolia and Singapore, due either to historical Chinese influence or a contemporary overseas Chinese population. The Sinosphere is different from the Sinophone world, which indicates regions where the Chinese language is spoken.

Imperial China was a major regional power in Eastern Asia and exerted influence on tributary states and neighboring states, including Japan, Korea, and Vietnam. These interactions brought ideological and cultural influences rooted in Confucianism, Buddhism, and Taoism. The four cultures were ruled by their respective emperors under similar imperial systems, furthermore, the adoption of the Confucian-based imperial examination system deeply influenced the bureaucracy and social structure of Korea and Vietnam. Chinese inventions influenced, and were in turn influenced by, innovations of the other cultures in governance, philosophy, science, and the arts. Literary Chinese became the written lingua franca for bureaucracy and communications, and Chinese characters became locally adapted as kanji in Japan, hanja in Korea, and chữ Hán in Vietnam.

Ziran, also rendered in the Wade-Giles romanization as tzu-jan, is a key concept in Taoism and East Asian Buddhism that literally means 'of its own' or 'by itself' and thus "naturally; natural; spontaneously; freely; in the course of events; of course; doubtlessly."

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.

In the study of comparative religion, the East Asian religions, form a subset of the Eastern religions which originated in East Asia.

This group includes Chinese religion overall, which further includes ancestor veneration, Chinese folk religion, Confucianism, Taoism and popular salvationist organisations (such as Yiguandao and Weixinism), as well as elements drawn from Mahayana Buddhism that form the core of Chinese and East Asian Buddhism at large. The group also includes Shinto and Tenrikyo of Japan, and Korean Shamanism, all of which combine shamanistic elements and indigenous ancestral worship with various influences from Chinese religions. Chinese salvationist religions have influenced the rise of Japanese new religions such Tenriism and Korean Jeungsanism; as these new religious movements draw upon indigenous traditions but are heavily influenced by Chinese philosophy and theology. All these religious traditions generally share core concepts of spirituality, divinity and world order, including Tao ('way') and Tian ('heaven').

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.

East Asian Yogācāra refers to the Mahayana Buddhist traditions in East Asia which developed out of the Indian Buddhist Yogācāra (lit. "yogic practice") systems (also known as Vijñānavāda, "the doctrine of consciousness" or Cittamātra, "mind-only"). In East Asian Buddhism, this school of Buddhist idealism was known as the "Consciousness-Only school" (traditional Chinese: 唯識宗; ; pinyin: Wéishí-zōng; Japanese pronunciation: Yuishiki-shū; Korean: 유식종).

The 4th-century brothers, Asaṅga and Vasubandhu, are considered the classic founders of Indian Yogacara school. The East Asian tradition developed through the work of numerous Buddhist thinkers working in Chinese. They include Bodhiruci, Ratnamati, Huiguang, Paramārtha, Jingying Huiyuan, Zhiyan, Xuanzang and his students Kuiji, Woncheuk and Dōshō.
