Zen in the context of "Japanese philosophy"

Ashikaga Takauji (足利 尊氏; August 18, 1305 – June 7, 1358) also known as Minamoto no Takauji was the founder and first shōgun of the Ashikaga shogunate. His rule began in 1338, beginning the Muromachi period of Japan, and ended with his death in 1358. He was a male-line descendant of the samurai of the (Minamoto) Seiwa Genji line (meaning they were descendants of Emperor Seiwa) who had settled in the Ashikaga area of Shimotsuke Province, in present-day Tochigi Prefecture.

According to Zen master and intellectual Musō Soseki, who enjoyed his favor and collaborated with him, Takauji had three qualities: he kept his cool in battle and was not afraid of death, he was merciful and tolerant, and he was very generous with those below him.

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.

Satori (Japanese: 悟り) is a Japanese Buddhist term for "awakening", "comprehension; understanding". The word derives from the Japanese verb satoru.

In the Zen Buddhist tradition, satori refers to a deep experience of kenshō, "seeing into one's true nature". Ken means "seeing," shō means "nature" or "essence".

A "journey of self-discovery" refers to a travel, pilgrimage, or series of events whereby a person attempts to determine how they feel, personally, about spiritual issues or priorities, rather than following the opinions of family, friends, neighborhood or peer pressure. The topic of self-discovery has been associated with Zen.

A related term is "finding oneself". There are different stages of finding oneself. Cultures from around the world have developed an array of modalities in the journey to discover oneself. In modern times practitioners and scientists have come together to create a map that brings clarity to the process of self-discovery. This is referred to as the levels of consciousness.

East Asian Buddhism or East Asian Mahayana is a collective term for the schools of Mahāyāna Buddhism which developed across East Asia and which rely on the Chinese Buddhist canon. These include the various forms of Chinese, Japanese, Korean, and Vietnamese Buddhism. East Asian Buddhists constitute the numerically largest body of Buddhist traditions in the world, numbering over half of the world's Buddhists.

East Asian forms of Buddhism all derive from the sinicized Buddhist schools which developed during the Han dynasty and the Song dynasty, and therefore are influenced by Chinese culture and philosophy. The spread of Buddhism to East Asia was aided by the trade networks of the Silk Road and the missionary work of generations of Indian and Asian Buddhists. Some of the most influential East Asian traditions include Chan (Zen), Nichiren Buddhism, Pure Land, Huayan, Tiantai, and Chinese Esoteric Buddhism. These schools developed new, uniquely East Asian interpretations of Buddhist texts and focused on the study of Mahayana sutras. According to Paul Williams, this emphasis on the study of the sutras contrasts with the Tibetan Buddhist attitude which sees the sutras as too difficult unless approached through the study of philosophical treatises (shastras).

Musō Soseki (夢窓 疎石; 1275 – October 20, 1351) was a Rinzai Zen Buddhist monk and teacher, and a calligrapher, poet and garden designer. The most famous monk of his time, he is also known as Musō Kokushi (夢窓国師; "national [Zen] teacher Musō"), an honorific conferred on him by Emperor Go-Daigo. His mother was the daughter of Hōjō Masamura (1264–1268), seventh Shikken (regent) of the Kamakura shogunate.

Ippen Shōnin (一遍上人) 1234/9–1289 was a Japanese Buddhist itinerant preacher (hijiri) whose movement, the Ji-shū (時宗; "Time sect") became one of the major currents of medieval Japanese Pure Land Buddhism. Born in modern Ehime Prefecture, he studied in the Seizan branch of Jōdo-shū before meeting with many Shingon and Tendai associated hijiri and then becoming a wandering holy man himself. During a pilgrimage to the Kumano Shrines, Ippen had an experience which inspired him to spread the Pure Land faith throughout Japan. Accompanied by bands of followers, he traveled throughout Japan teaching that salvation lay in the single-minded invocation of Amida’s Name and that the very moment of recitation unites the reciter with the timeless enlightenment of the Buddha. Ippen traveled over fifteen hundred miles, visiting every major population center and devotional center in Japan, such as Kumano, Zenkōji, Taimadera, and Mt. Kōya.

In his itinerant ministry, Ippen combined the devotional recitation of the nembutsu with ecstatic dancing, and the distribution of ofuda (talismans) inscribed with Amida’s Name, which he handed to people as symbols of faith and rebirth in the Pure Land. His teachings blended the Pure Land ideal of Other-Power with Zen non-dualism and the folk religious practices of wandering ascetics. Rejecting all self-powered efforts and sectarian distinctions, Ippen held that the simple recitation of even a single nembutsu invariably linked one with Amida Buddha's enlightenment, assuring our birth in the Pure Land. Ippen’s radical vision of faith and his insistence that the heart can attain birth in the Pure Land while the body remains in this world gave rise to a popular movement that appealed to all social classes. His life is outlined in the Ippen Hijiri-e, a series of narrative painted scrolls which are the main historical source for his life and activities.

In Chan and Zen Buddhism, dharma transmission is a custom in which a person is established as a "successor in an unbroken lineage of teachers and disciples, a spiritual 'bloodline' (kechimyaku) theoretically traced back to the Buddha himself." The dharma lineage reflects the importance of family-structures in ancient China, and forms a symbolic and ritual recreation of this system for the monastic "family".

In Rinzai-Zen, inka shōmei (印可証明) is ideally "the formal recognition of Zen's deepest realisation", but practically it is being used for the transmission of the "true lineage" of the masters (shike) of the training halls. There are only about fifty to eighty of such inka shōmei-bearers in Japan.
