SamadhiSamādhi (Pali and समाधि), in Hinduism, Buddhism, Jainism, Sikhism and yogic schools, is a state of meditative consciousness. In Buddhism, it is the last of the eight elements of the Noble Eightfold Path. In the Ashtanga Yoga tradition, it is the eighth and final limb identified in the Yoga Sutras of Patanjali. In the oldest Buddhist sutras, on which several contemporary western Theravada teachers rely, it refers to the development of an investigative and luminous mind which is equanimous and mindful.
VedanāVedanā (Pāli and Sanskrit: वेदना) is an ancient term traditionally translated as either "feeling" or "sensation." In general, vedanā refers to the pleasant, unpleasant and neutral sensations that occur when our internal sense organs come into contact with external sense objects and the associated consciousness. Vedanā is identified as valence or "hedonic tone" in psychology. Vedanā is identified within the Buddhist teaching as follows: One of the seven universal mental factors in the Theravāda Abhidharma.
PratītyasamutpādaPratītyasamutpāda (Sanskrit: प्रतीत्यसमुत्पाद, Pāli: paṭiccasamuppāda), commonly translated as dependent origination, or dependent arising, is a key doctrine in Buddhism shared by all schools of Buddhism. It states that all dharmas (phenomena) arise in dependence upon other dharmas: "if this exists, that exists; if this ceases to exist, that also ceases to exist". The basic principle is that all things (dharmas, phenomena, principles) arise in dependence upon other things.
Pre-sectarian BuddhismPre-sectarian Buddhism, also called early Buddhism, the earliest Buddhism, original Buddhism, and primitive Buddhism, is Buddhism as theorized to have existed before the various Early Buddhist schools developed, around 250 BCE (followed by later subsects of Buddhism). The contents and teachings of this pre-sectarian Buddhism must be deduced or re-constructed from the earliest Buddhist texts, which by themselves are already sectarian. The whole subject remains intensely debated by scholars, not all of whom believe a meaningful reconstruction is possible.
Shikantazais Dogen's Japanese translation of the Chinese phrase zhǐguǎn dǎzuò (只管打坐 / 祇管 打坐), "just sitting." The phrase was used by his teacher Rujing, a monk of the Caodong school of Chan Buddhism, to refer to the meditation-practice called "Silent Illumination" (), or "Serene Reflection," taught by the Caodong master Hongzhi Zhengjue (1091-1157). In Japan, it is associated with the Zen Soto school. In shikantaza one does not focus attention on a specific object (such as the breath); instead, practitioners "just sit" in a state of conscious awareness.
BhavanaBhāvanā (Pali; Sanskrit: भावना, also bhāvanā) literally means "development" or "cultivating" or "producing" in the sense of "calling into existence". It is an important concept in Buddhist practice (Patipatti). The word bhavana normally appears in conjunction with another word forming a compound phrase such as citta-bhavana (the development or cultivation of the heart/mind) or metta-bhavana (the development/cultivation of lovingkindness). When used on its own, bhavana signifies contemplation and 'spiritual cultivation' generally.
Dhamma vicayaIn Buddhism, dhamma vicaya (Pali; dharma-) has been variously translated as the "analysis of qualities," "discrimination of dhammas," "discrimination of states," "investigation of doctrine," and "searching the Truth." The meaning is ambivalent; it implies the investigation of the Buddhist teachings (dhamma), but also the application of discernment to body-mind phenomena in order to apply right effort, giving way to entry into the first jhana.
Five hindrancesIn the Buddhist tradition, the five hindrances (පඤ්ච නීවරණ; Pali: ) are identified as mental factors that hinder progress in meditation and in daily life. In the Theravada tradition, these factors are identified specifically as obstacles to the jhānas (stages of concentration) within meditation practice. Within the Mahayana tradition, the five hindrances are identified as obstacles to samatha (tranquility) meditation. Contemporary Insight Meditation teachers identify the five hindrances as obstacles to mindfulness meditation.
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.
Effects of meditationThe psychological and physiological effects of meditation have been studied. In recent years, studies of meditation have increasingly involved the use of modern instruments, such as fMRI and EEG, which are able to observe brain physiology and neural activity in living subjects, either during the act of meditation itself or before and after meditation. Correlations can thus be established between meditative practices and brain structure or function.
