VedasThe Vedas (ˈveɪdəz or ˈviːdəz, , वेदः) are a large body of religious texts originating in ancient India. Composed in Vedic Sanskrit, the texts constitute the oldest layer of Sanskrit literature and the oldest scriptures of Hinduism. There are four Vedas: the Rigveda, the Yajurveda, the Samaveda and the Atharvaveda. Each Veda has four subdivisions – the Samhitas (mantras and benedictions), the Aranyakas (text on rituals, ceremonies, sacrifices and symbolic-sacrifices), the Brahmanas (commentaries on rituals, ceremonies and sacrifices), and the Upanishads (texts discussing meditation, philosophy and spiritual knowledge).
Adi ShankaraAdi Shankara, also called Adi Shankaracharya (Ādi Śaṅkara, Ādi Śaṅkarācārya, aːdɪ ɕɐŋkɐraːt͡ɕaːrjɐ), was an 8th-century Indian Vedic scholar and teacher (acharya). His works present a harmonizing reading of the sastras, with liberating knowledge of the self at its core, synthesizing the Advaita Vedanta teachings of his time. Due to his later fame, over 300 texts are attributed to him, including commentaries (Bhāṣya), introductory topical expositions (Prakaraṇa grantha) and poetry (Stotra).
SamkhyaSamkhya or Sankya (ˈsɑːŋkjə; sāṃkhya) is a dualistic orthodox school of Hindu philosophy. It views reality as composed of two independent principles, Puruṣa ('consciousness' or spirit) and Prakṛti (nature or matter, including the human mind and emotions). Puruṣa is the witness-consciousness. It is absolute, independent, free, beyond perception, above any experience by mind or senses, and impossible to describe in words. Unmanifest Prakriti is matter or nature.
Advaita VedantaAdvaita Vedanta (ʌdˈvaɪtə_vɛˈdɑːntə; अद्वैत वेदान्त, ) is a school of Hindu philosophy and a Hindu sādhanā, a path of spiritual discipline and experience. In a narrow sense it refers to the oldest extant scholarly tradition of the orthodox Hindu school Vedānta, written in Sanskrit; in a broader sense it refers to a popular, syncretic tradition, blending Vedānta with other traditions and producing works in vernacular.
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.
PurushaPurusha (पुरुष, ) is a complex concept whose meaning evolved in Vedic and Upanishadic times. Depending on source and historical timeline, it means the cosmic being or self, awareness, and universal principle. In early Vedas, Purusha was a cosmic being whose sacrifice by the gods created all life. This was one of many creation myths discussed in the Vedas. In the Upanishads, the Purusha concept refers to the abstract essence of the Self, Spirit and the Universal Principle that is eternal, indestructible, without form, and is all-pervasive.
RigvedaThe Rigveda or Rig Veda (ऋग्वेद , from "praise" and "knowledge") is an ancient Indian collection of Vedic Sanskrit hymns (sūktas). It is one of the four sacred canonical Hindu texts (śruti) known as the Vedas. Only one Shakha of the many survive today, namely the Śakalya Shakha. Much of the contents contained in the remaining Shakhas are now lost or are not available in the public forum. The Rigveda is the oldest known Vedic Sanskrit text. Its early layers are among the oldest extant texts in any Indo-European language.
YogaYoga (ˈjoʊgə; योग joːɡɐ) is a group of physical, mental, and spiritual practices or disciplines which originated in ancient India and aim to control (yoke) and still the mind, recognizing a detached witness-consciousness untouched by the mind (Chitta) and mundane suffering (Duḥkha). There is a wide variety of schools of yoga, practices, and goals in Hinduism, Buddhism, and Jainism, and traditional and modern yoga is practiced worldwide. Yoga-like practices were first mentioned in the ancient Hindu text known as Rigveda.
