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.
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.
Brahma SutrasThe Brahma Sūtras (ब्रह्मसूत्राणि), also known as the Vedanta Sutra (Sanskrit: वेदान्त सूत्र), Shariraka Sutra, and Bhikshu-sutra, are a Sanskrit text which synthesizes and harmonizes Upanishadic ideas and practices. It is attributed to the sages Bādarāyaṇa and Vyāsa, but probably an accumulation of incremental additions and changes by various authors to an earlier work, completed in its surviving form in approx. 400–450 CE. The oldest version may be composed between 500 BCE and 200 BCE, with 200 BCE being the most likely date.
BuddhismBuddhism (ˈbʊdɪzəm , USalsoˈbuːd- ), also known as Buddha Dharma, and Dharmavinaya (), is an Indian religion or philosophical tradition based on teachings attributed to the Buddha. It originated in the eastern Gangetic plain as a śramaṇa–movement in the 5th century BCE, and gradually spread throughout much of Asia via the Silk Road. It is the world's fourth-largest religion, with over 520 million followers (Buddhists) who comprise seven percent of the global population.
VaisheshikaVaisheshika or Vaiśeṣika (vaɪˈʃɛʃɪkə; वैशेषिक) is one of the six schools of Hindu philosophy from ancient India. In its early stages, the Vaiśeṣika was an independent philosophy with its own metaphysics, epistemology, logic, ethics, and soteriology. Over time, the Vaiśeṣika system became similar in its philosophical procedures, ethical conclusions and soteriology to the Nyāya school of Hinduism, but retained its difference in epistemology and metaphysics.
Yoga (philosophy)Yoga philosophy is one of the six major orthodox schools of Hinduism, though it is only at the end of the first millennium CE that Yoga is mentioned as a separate school of thought in Indian texts, distinct from Samkhya. Ancient, medieval and most modern literature often refers to Yoga-philosophy simply as Yoga. A systematic collection of ideas of Yoga is found in the Yoga Sutras of Patanjali, a key text of Yoga which has influenced all other schools of Indian philosophy.
Guṇa(गुण) is a concept in Hinduism and Sikhism, which can be translated as "quality, peculiarity, attribute, property". The concept is originally notable as a feature of Samkhya philosophy. The guṇas are now a key concept in nearly all schools of Hindu philosophy. There are three guṇas, according to this worldview, that have always been and continue to be present in all things and beings in the world. These three guṇas are called: (goodness, calmness, harmonious), (passion, activity, movement), and (ignorance, inertia, laziness).
SmritiSmriti (स्मृति, IAST: ), literally "that which is remembered" are a body of Hindu texts usually attributed to an author, traditionally written down, in contrast to Śrutis (the Vedic literature) considered authorless, that were transmitted verbally across the generations and fixed. Smriti is a derivative secondary work and is considered less authoritative than Sruti in Hinduism, except in the Mimamsa school of Hindu philosophy. The authority of smriti accepted by orthodox schools, is derived from that of shruti, on which it is based.
SutraSutra (सूत्र) in Indian literary traditions refers to an aphorism or a collection of aphorisms in the form of a manual or, more broadly, a condensed manual or text. Sutras are a genre of ancient and medieval Indian texts found in Hinduism, Buddhism and Jainism. In Hinduism, sutras are a distinct type of literary composition, a compilation of short aphoristic statements. Each sutra is any short rule, like a theorem distilled into few words or syllables, around which teachings of ritual, philosophy, grammar, or any field of knowledge can be woven.
ŚrutiShruti (श्रुति, , ɕrʊtɪ) in Sanskrit means "that which is heard" and refers to the body of most authoritative, ancient religious texts comprising the central canon of Hinduism. Manusmriti states: Śrutistu vedo vijñeyaḥ (Devanagari: श्रुतिस्तु वेदो विज्ञेयः) meaning, "Know that Vedas are Śruti". Thus, it includes the four Vedas including its four types of embedded texts—the Samhitas, the Upanishads, the Brahmanas and the Aranyakas. Śrutis have been variously described as a revelation through anubhava (direct experience), or of primordial origins realized by ancient Rishis.
