MahayanaMahāyāna (महायान, ˌmɑːhəˈjɑːnə ; Great Vehicle) is a term for a broad group of Buddhist traditions, texts, philosophies, and practices. Mahāyāna Buddhism developed in ancient India (1st century BCE onwards) and is considered one of the three main existing branches of Buddhism, the other being Theravāda and Vajrayāna. 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.
TetralemmaThe tetralemma is a figure that features prominently in the logic of India. It states that with reference to any a logical proposition X, there are four possibilities: (affirmation) (negation) (both) (neither) The history of fourfold negation, the Catuskoti (Sanskrit), is evident in the logico-epistemological tradition of India, given the categorical nomenclature Indian logic in Western discourse.
Ultimate realityUltimate reality is "the supreme, final, and fundamental power in all reality". This heavily overlaps with the concept of the Absolute in certain philosophies. Buddhism In Theravada Buddhism, Nirvana is ultimate reality. Nirvana is described in negative terms; it is unconstructed and unconditioned. In some strands of Mahayana Buddhism, the Buddha-nature or the Dharmakaya is seen as ultimate reality. Other strands of Buddhism reject the notion of ultimate reality, regarding any existent as empty (sunyata) of inherent existence (svabhava).
AbhidharmaThe Abhidharma are ancient (third century BCE and later) Buddhist texts which contain detailed scholastic presentations of doctrinal material appearing in the Buddhist sutras. It also refers to the scholastic method itself as well as the field of knowledge that this method is said to study. Bhikkhu Bodhi calls it "an abstract and highly technical systemization of the [Buddhist] doctrine," which is "simultaneously a philosophy, a psychology and an ethics, all integrated into the framework of a program for liberation.
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.
Tathāgatagarbha sūtrasThe Tathāgatagarbha sūtras are a group of Mahayana sutras that present the concept of the "womb" or "embryo" (garbha) of the tathāgata, the buddha. Every sentient being has the possibility to attain Buddhahood because of the tathāgatagarbha. This concept originated in India but was a major influence in the development of East Asian Buddhism, where it was equated with the concept of Buddhadhātu, "buddha-element" or "buddha-nature". The Tathāgatagarbha sūtras include the Tathāgatagarbha Sūtra, Śrīmālādevī Siṃhanāda Sūtra, Mahāyāna Mahāparinirvāṇa Sūtra and the Aṅgulimālīya Sūtra.
CatuṣkoṭiCatuṣkoṭi (Sanskrit; Devanagari: चतुष्कोटि, , Sinhalese:චතුස්කෝටිකය) refers to logical argument(s) of a 'suite of four discrete functions' or 'an indivisible quaternity' that has multiple applications and has been important in the Indian logic and the Buddhist logico-epistemological traditions, particularly those of the Madhyamaka school. In particular, the catuṣkoṭi is a "four-cornered" system of argumentation that involves the systematic examination of each of the 4 possibilities of a proposition, P: P; that is being.
Nonduality (spirituality)_Nonduality Nonduality, also called nondualism and nondual awareness, is a fuzzy concept, originating in Indian philosophy and religion, implying that the universe forms a whole that can be experienced as such by the human mind. The Asian terms from which it is derived have specific, somewhat different meanings depending on context, but common elements are: the idea that everything is interconnected, forming a singular unity that suggests the personal self is an illusion; an awareness of this unity, without the usual strict distinction between an observer and the things observed; and thinking that lacks dualistic concepts in order to support this view and experience.
AnattāIn Buddhism, the term anattā (Pali: अनत्ता) or anātman (Sanskrit: अनात्मन्) refers to the doctrine of "non-self" – that no unchanging, permanent self or essence can be found in any phenomenon. While often interpreted as a doctrine denying the existence of a self, anatman is more accurately described as a strategy to attain non-attachment by recognizing everything as impermanent, while staying silent on the ultimate existence of an unchanging essence.
Indian philosophyIndian philosophy refers to philosophical traditions of the Indian subcontinent. A traditional Hindu classification divides āstika and nāstika schools of philosophy, depending on one of three alternate criteria: whether it believes the Vedas as a valid source of knowledge; whether the school believes in the premises of Brahman and Atman; and whether the school believes in afterlife and Devas. There are six major (āstika) schools of Vedic philosophy—Nyaya, Vaisheshika, Samkhya, Yoga, Mīmāṃsā and Vedanta—and five major heterodox (nāstika or sramanic) schools—Jain, Buddhist, Ajivika, Ajñana, and Charvaka.
