Mahābhūta
''Mahābhūta'' is Sanskrit and Pāli for "great element". However, very few scholars define the four mahābhūtas in a broader sense as the four fundamental aspects of physical reality. Hinduism In Hinduism's sacred literature, the "great" or "gross" elements (''mahābhūta'') are fivefold: space (or "ether"), air, fire, water and earth. See also the Samkhya Karika of Ishvara Krishna, verse 22. For instance, the describes the five "sheaths" of a person (Sanskrit: '' purua''), starting with the grossest level of the five evolving great elements: :From this very self ('' tman'') did space come into being; from space, air; from air, fire; from fire, the waters, from the waters, the earth; from the earth, plants; from plants, food; and from food, man.... Different from and lying within this man formed from the essence of food is the self (''tman'') consisting of lifebreath.... Different from and lying within this self consisting of breath is the self (''tman'') consisting of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sanskrit
Sanskrit (; attributively , ; nominally , , ) is a classical language belonging to the Indo-Aryan branch of the Indo-European languages. It arose in South Asia after its predecessor languages had diffused there from the northwest in the late Bronze Age. Sanskrit is the sacred language of Hinduism, the language of classical Hindu philosophy, and of historical texts of Buddhism and Jainism. It was a link language in ancient and medieval South Asia, and upon transmission of Hindu and Buddhist culture to Southeast Asia, East Asia and Central Asia in the early medieval era, it became a language of religion and high culture, and of the political elites in some of these regions. As a result, Sanskrit had a lasting impact on the languages of South Asia, Southeast Asia and East Asia, especially in their formal and learned vocabularies. Sanskrit generally connotes several Old Indo-Aryan language varieties. The most archaic of these is the Vedic Sanskrit found in the Rig Veda, a colle ...

Viscosity
The viscosity of a fluid is a measure of its resistance to deformation at a given rate. For liquids, it corresponds to the informal concept of "thickness": for example, syrup has a higher viscosity than water. Viscosity quantifies the internal frictional force between adjacent layers of fluid that are in relative motion. For instance, when a viscous fluid is forced through a tube, it flows more quickly near the tube's axis than near its walls. Experiments show that some stress (such as a pressure difference between the two ends of the tube) is needed to sustain the flow. This is because a force is required to overcome the friction between the layers of the fluid which are in relative motion. For a tube with a constant rate of flow, the strength of the compensating force is proportional to the fluid's viscosity. In general, viscosity depends on a fluid's state, such as its temperature, pressure, and rate of deformation. However, the dependence on some of these properties is ...

Plasma (physics)
Plasma () 1, where \nu_ is the electron gyrofrequency and \nu_ is the electron collision rate. It is often the case that the electrons are magnetized while the ions are not. Magnetized plasmas are ''anisotropic'', meaning that their properties in the direction parallel to the magnetic field are different from those perpendicular to it. While electric fields in plasmas are usually small due to the plasma high conductivity, the electric field associated with a plasma moving with velocity \mathbf in the magnetic field \mathbf is given by the usual Lorentz force, Lorentz formula \mathbf = -\mathbf\times\mathbf, and is not affected by Debye shielding. Mathematical descriptions To completely describe the state of a plasma, all of the particle locations and velocities that describe the electromagnetic field in the plasma region would need to be written down. However, it is generally not practical or necessary to keep track of all the particles in a plasma. Therefore, plasma physicist ...

Science
Science is a systematic endeavor that builds and organizes knowledge in the form of testable explanations and predictions about the universe. Science may be as old as the human species, and some of the earliest archeological evidence for scientific reasoning is tens of thousands of years old. The earliest written records in the history of science come from Ancient Egypt and Mesopotamia in around 3000 to 1200 BCE. Their contributions to mathematics, astronomy, and medicine entered and shaped Greek natural philosophy of classical antiquity, whereby formal attempts were made to provide explanations of events in the physical world based on natural causes. After the fall of the Western Roman Empire, knowledge of Greek conceptions of the world deteriorated in Western Europe during the early centuries (400 to 1000 CE) of the Middle Ages, but was preserved in the Muslim world during the Islamic Golden Age and later by the efforts of Byzantine Greek scholars who brought Greek ...

Theravada Buddhism
''Theravāda'' () ( si, ථේරවාදය, my, ထေရဝါဒ, th, เถรวาท, km, ថេរវាទ, lo, ເຖຣະວາດ, pi, , ) 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 ''Dharma (Buddhism), Buddha Dhamma'' in the Pāli Canon for over two millennia. The Pāli Canon is the most complete Buddhist canon surviving in a Indo-Aryan languages, classical Indian language, Pali, Pāli, which serves as the school's sacred language and ''lingua franca''.Crosby, Kate (2013), ''Theravada Buddhism: Continuity, Diversity, and Identity'', p. 2. In contrast to ''Mahāyāna'' and ''Vajrayāna'', Theravāda tends to be conservative in matters of doctrine (''pariyatti'') and monastic discipline (''vinaya''). One element of this conservatism is the fact that Theravāda rejects the authenticity of the Mahayana sutras (which appeared c. ...

Meta-analysis
A meta-analysis is a statistical analysis that combines the results of multiple scientific studies. Meta-analyses can be performed when there are multiple scientific studies addressing the same question, with each individual study reporting measurements that are expected to have some degree of error. The aim then is to use approaches from statistics to derive a pooled estimate closest to the unknown common truth based on how this error is perceived. Meta-analytic results are considered the most trustworthy source of evidence by the evidence-based medicine literature.Herrera Ortiz AF., Cadavid Camacho E, Cubillos Rojas J, Cadavid Camacho T, Zoe Guevara S, Tatiana Rincón Cuenca N, Vásquez Perdomo A, Del Castillo Herazo V, & Giraldo Malo R.

Chandrakirti
Chandrakirti (; ; , 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 () 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. However, by the 11th and 12th centuries, his work became influential in the north, especially in Kashmir and in Tibet. Over time, Chandrakirti became a major source for the study of madhyamaka philosophy in Tibetan Buddhism. As noted by Kevin A. Vose, Chandrakirti is seen by many Tibetan Buddhists as offering "the most thorough and accurate vision of Nāgārjuna's emptiness, which, in turn, most fully represents the final truth of the Buddha's teaching."Vose 2015, pp. 2, 6. He is considered by Tibetans to be the main exponent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vajrayana
Vajrayāna ( sa, वज्रयान, "thunderbolt vehicle", "diamond vehicle", or "indestructible vehicle"), along with Mantrayāna, Guhyamantrayāna, Tantrayāna, Secret Mantra, Tantric Buddhism, and Esoteric Buddhism, are names referring to Buddhism, Buddhist traditions associated with Tantra and "Secret Mantra", which developed in the Medieval India, medieval Indian subcontinent and spread to Tibet, Nepal, other Himalayan states, East Asia, and Mongolia. Vajrayāna practices are connected to specific lineages in Buddhism, through the teachings of lineage holders. Others might generally refer to texts as the Buddhist Tantras. It includes practices that make use of mantras, dharanis, mudras, mandalas and the visualization of deities and Buddhas. Traditional Vajrayāna sources say that the tantras and the lineage of Vajrayāna were taught by Gautama Buddha, Śākyamuni Buddha and other figures such as the bodhisattva Vajrapani and Padmasambhava. Contemporary historians of Bu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mahayana
''Mahāyāna'' (; "Great Vehicle") is a term for a broad group of Buddhist traditions, texts, philosophies, and practices. Mahāyāna Buddhism developed in India (c. 1st century BCE onwards) and is considered one of the three main existing branches of Buddhism (the other being ''Theravāda'' and Vajrayana).Harvey (2013), p. 189. 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. These include the Mahāyāna Sūtras and their emphasis on the ''bodhisattva'' path and ''Prajñāpāramitā''. ''Vajrayāna'' or Mantra traditions are a subset of Mahāyāna, which make use of numerous tantric methods considered to be faster and more powerful at achieving Buddhahood by Vajrayānists. "Mahāyāna" also refers to the path of the bodhisattva striving to become a fully awakened Buddha (''samyaksaṃbuddha'') for the benefit of all sentient beings, and is thus als ...
