ZenZen (; ; ; ) is a school of Mahayana Buddhism that originated in China during the Tang dynasty, known as the Chan School (Chánzong 禪宗), and later developed into various sub-schools and branches. From China, Chán spread south to Vietnam and became Vietnamese Thiền, northeast to Korea to become Seon Buddhism, and east to Japan, becoming Japanese Zen. The term Zen is derived from the Japanese pronunciation of the Middle Chinese word 禪 (chán), an abbreviation of 禪那 (chánnà), which is a Chinese transliteration of the Sanskrit word ध्यान dhyāna ("meditation").
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.
MetaphysicsMetaphysics is the branch of philosophy that studies the fundamental nature of reality. This includes the first principles of: being or existence, identity, change, space and time, cause and effect, necessity, actuality, and possibility. Metaphysics is considered one of the four main branches of philosophy, along with epistemology, logic, and ethics. It includes questions about the nature of consciousness and the relationship between mind and matter, between substance and attribute, and between potentiality and actuality.
Hindu philosophyHindu philosophy or Vedic philosophy is the set of Indian philosophical systems developing alongside the religion of Hinduism and emerging in the Iron and Classical periods, which consists of six orthodox schools of thought (shad-darśana): Samkhya, Yoga, Nyaya, Vaisheshika, Mimamsa and Vedanta. In Indian tradition, the word used for philosophy is Darshana (viewpoint or perspective), from the Sanskrit root drish ('to see, to experience'). These are also called the āstika philosophical traditions: those that accept the Vedas as an authoritative, important source of knowledge.
TheravadaTheravāda (ˌtɛrəˈvɑːdə, School of the Elders) is the most commonly accepted name of Buddhism's oldest existing school. The school's adherents, termed Theravādins, have preserved their version of Gautama Buddha's teaching or Buddha Dhamma in the Pāli Canon for over two millennia. The Pāli Canon is the most complete Buddhist canon surviving in a classical Indian language, Pāli, which serves as the school's sacred language and lingua franca.
ChandrakirtiChandrakirti (; ; 600-650, meaning "glory of the moon" in Sanskrit) or "Chandra" was a Buddhist scholar of the Madhyamaka school and a noted commentator on the works of Nagarjuna (150-250 CE) and those of his main disciple, Aryadeva. He wrote two influential works on madhyamaka, the Prasannapadā and the Madhyamakāvatāra. Chandrakirti does not seem to have been very influential during the 7th to 10 centuries, and his works were never translated into Chinese.
TiantaiTiantai or T'ien-t'ai () is an East Asian Buddhist school of Mahāyāna Buddhism that developed in 6th-century China. Tiantai Buddhism emphasizes the "One Vehicle" (Ekayāna) doctrine derived from the Lotus Sūtra as well as Mādhyamaka philosophy, particularly as articulated in the works of the 4th patriarch Zhiyi (538–597 CE). Brook Ziporyn, professor of ancient and medieval Chinese religion and philosophy, states that Tiantai Buddhism is "the earliest attempt at a thoroughgoing Sinitic reworking of the Indian Buddhist tradition.
BhāvivekaBhāviveka, also called Bhāvaviveka (; ), and Bhavya was a sixth-century (c. 500 – c. 570) madhyamaka Buddhist philosopher. Alternative names for this figure also include Bhavyaviveka, Bhāvin, Bhāviviveka, Bhagavadviveka and Bhavya. Bhāviveka is the author of the Madhyamakahrdaya (Heart of the Middle), its auto-commentary the Tarkajvālā (Blaze of Reasoning) and the Prajñāpradīpa (Lamp for Wisdom). In Tibetan Buddhism Bhāviveka is regarded as the founder of the svātantrika tradition of mādhyamaka, as opposed to the prāsaṅgika madhyamaka of Chandrakirti.
Two truths doctrineThe Buddhist doctrine of the two truths (Sanskrit: dvasatya, ) differentiates between two levels of satya (Sanskrit; Pali: sacca; word meaning "truth" or "reality") in the teaching of the Śākyamuni Buddha: the "conventional" or "provisional" (saṁvṛti) truth, and the "ultimate" (paramārtha) truth. The exact meaning varies between the various Buddhist schools and traditions. The best known interpretation is from the Madhyamaka school of Mahāyāna Buddhism, whose founder was the Indian Buddhist monk and philosopher Nāgārjuna.
Svatantrika–Prasaṅgika distinctionThe Svātantrika–Prāsaṅgika distinction is a doctrinal distinction made within Tibetan Buddhism between two stances regarding the use of logic and the meaning of conventional truth within the presentation of Madhyamaka. Svātantrika is a category of Madhyamaka viewpoints attributed primarily to the 6th-century Indian scholar Bhāviveka. Bhāviveka criticised Buddhapalita’s abstinence from syllogistic reasoning in his commentary on Nāgārjuna.
