Saichōwas a Japanese Buddhist monk credited with founding the Tendai school of Buddhism based on the Chinese Tiantai school he was exposed to during his trip to Tang China beginning in 804. He founded the temple and headquarters of Tendai at Enryaku-ji on Mount Hiei near Kyoto. He is also said to have been the first to bring tea to Japan. After his death, he was awarded the posthumous title of Dengyō Daishi (伝教大師). Saichō was born in the year 767 in the city of Ōmi, in present Shiga Prefecture, with the given name of Hirono.
FazangFazang () (643–712) was a Chinese Buddhist scholar, translator, and religious leader of the Tang dynasty. He was the third patriarch of the Huayan school of East Asian Buddhism, a key figure at the Chinese Imperial Court, and an influential Chinese Buddhist philosopher. Some scholars see him as the main figure in or even de facto founder of the Huayan school. Fazang's ancestors came from the Central Asian region of Sogdia, a major center for Silk Road trade, but he was born in the Tang capital of Chang'an (now Xi'an), where his family had become culturally Chinese.
SōtōSōtō Zen or the Sōtō school is the largest of the three traditional sects of Zen in Japanese Buddhism (the others being Rinzai and Ōbaku). It is the Japanese line of the Chinese Cáodòng school, which was founded during the Tang dynasty by Dòngshān Liánjiè. It emphasizes Shikantaza, meditation with no objects, anchors, or content. The meditator strives to be aware of the stream of thoughts, allowing them to arise and pass away without interference.
RatnagotravibhāgaThe Ratnagotravibhāga (Sanskrit, abbreviated as RGV, meaning: Analysis of the Jeweled Lineage, Investigating the Jewel Disposition) and its vyākhyā commentary (abbreviated RGVV to refer to the RGV verses along with the embedded commentary), is an influential Mahāyāna Buddhist treatise on buddha-nature (a.k.a. tathāgatagarbha). The text is also known as the Mahāyānottaratantraśāstra (The Ultimate Teaching of the Mahāyāna). The RGVV was originally composed in Sanskrit, likely between the middle of the third century and no later than 433 CE.
Indra's netIndra's net (also called Indra's jewels or Indra's pearls, Sanskrit Indrajāla, Chinese: 因陀羅網) is a metaphor used to illustrate the concepts of Śūnyatā (emptiness), pratītyasamutpāda (dependent origination), and interpenetration in Buddhist philosophy. The metaphor's earliest known reference is found in the Atharva Veda. It was further developed by the Mahayana school in the 3rd century Buddhāvataṃsaka Sūtra and later by the Huayan school between the 6th and 8th centuries.
TrikayaThe Trikāya doctrine (त्रिकाय, lit. "three bodies"; , ) is a fundamental doctrine within Mahayana and Vajrayana Buddhism that delineates the multidimensional nature of a Buddha's existence. This concept posits that a Buddha has three distinct bodies or aspects, each representing a different facet of enlightenment. The first body is the Dharmakaya, often referred to as the "Dharma body" or ultimate reality. This embodies the essence of enlightenment itself, encompassing concepts like emptiness, Buddha nature, and pure existence beyond material and spiritual forms.
UpayaUpaya (Sanskrit: उपाय, , expedient means, pedagogy) is a term used in Buddhism to refer to an aspect of guidance along the Buddhist paths to liberation where a conscious, voluntary action "is driven by an incomplete reasoning" about its direction. Upaya is often used with kaushalya (कौशल्य, "cleverness"), upaya-kaushalya meaning "skill in means". Upaya-kaushalya is a concept emphasizing that practitioners may use their own specific methods or techniques that fit the situation in order to gain enlightenment.
Essence-FunctionEssence-Function (體用, Chinese pinyin: tǐ yòng, Korean: che-yong), also called Substance and Function, is a key concept in Chinese philosophy and other Far-Eastern philosophies. Essence is Absolute Reality, the fundamental "cause" or origin, while Function is relative or concrete reality, the concrete manifestation of Essence. Ti and yong do not represent two separate things, such as Absolute Reality and Concrete Reality. They are always two, flexibly-viewed aspects of a single thing.
Da zhidu lunThe Dà zhìdù lùn (abbreviated DZDL), (Chinese: 大智度論, Wade-Giles: Ta-chih-tu lun; Japanese: Daichido-ron (as in Taishō Tripiṭaka no. 1509); The Treatise on the Great Prajñāpāramitā) is a massive Mahāyāna Buddhist treatise and commentary on the Pañcaviṃśatisāhasrikā Prajñāpāramitā Sūtra (The Sūtra of Transcendental Wisdom in Twenty-five Thousand Lines). The title has been reconstructed into Sanskrit as Mahāprajñāpāramitopadeśa. and Mahāprajñāpāramitāśāstra. It is an encyclopedic compendium or summa of Mahayana Buddhist doctrine.
SubitismThe term subitism points to sudden awakening, the idea that insight into Buddha-nature, or the nature of mind, is "sudden," c.q. "in one glance," "uncovered all together," or "together, completely, simultaneously," in contrast to "successively or being uncovered one after the other." It may be posited as opposite to gradualism, the original Buddhist approach which says that following the dharma can be achieved only step by step, through an arduous practice.
