Yoga in the context of Rigveda

Hinduism (/ˈhɪnduˌɪzəm/) is an umbrella term for a range of Indian religious and spiritual traditions (sampradayas) that are unified by adherence to the concept of dharma, a cosmic order maintained by its followers through rituals and righteous living, as expounded in the Vedas. The word Hindu is an exonym, and while Hinduism has been called the oldest surviving religion in the world, it is also described by the 19th century term Sanātana Dharma (lit. 'eternal dharma'). Vaidika Dharma (lit. 'Vedic dharma') and Arya Dharma are historical endonyms for Hinduism.

Hinduism entails diverse systems of thought, marked by a range of shared concepts that discuss theology, mythology, and other topics in textual sources. Hindu texts have been classified into Śruti (lit. 'heard') and Smṛti (lit. 'remembered'). The major Hindu scriptures are the Vedas, the Upanishads, the Puranas, the Mahabharata (including the Bhagavad Gita), the Ramayana, and the Agamas. Prominent themes in Hindu beliefs include karma (action, intent and consequences), saṃsāra (the cycle of death and rebirth) and the four Puruṣārthas, proper goals or aims of human life, namely: dharma (ethics/duties), artha (prosperity/work), kama (desires/passions) and moksha (liberation/emancipation from passions and ultimately saṃsāra). Hindu religious practices include devotion (bhakti), worship (puja), sacrificial rites (yajna), and meditation (dhyana) and Yoga. Hinduism has no central doctrinal authority and many Hindus do not claim to belong to any denomination. However, scholarly studies notify four major denominations: Shaivism, Vaishnavism, Shaktism and Smartism. The six Āstika schools of Hindu philosophy that recognise the authority of the Vedas are: Sankhya, Yoga, Nyaya, Vaisheshika, Mīmāṃsā, and Vedanta.

The Bhagavad Gita (/ˈbʌɡəvəd ˈɡiːtɑː/; Sanskrit: भगवद्गीता, IPA: [ˌbʱɐɡɐʋɐd ˈɡiːtɑː], romanized: bhagavad-gītā, lit. 'God's song'), often referred to as the Gita (IAST: gītā), is a Hindu scripture, likely composed in the second or first century BCE, which forms part of the epic poem Mahabharata. The Gita is a synthesis of various strands of Indian religious thought, including the Vedic concept of dharma (duty, rightful action); Sankhya-based yoga and jnana (knowledge); and bhakti (devotion). Among the Hindu traditions, the Gita holds a unique pan-Hindu influence as the most prominent sacred text and is a central text in the Vedanta and Vaishnava traditions.

While traditionally attributed to the sage Veda Vyasa, the Gita is historiographically regarded as a composite work by multiple authors. Incorporating teachings from the Upanishads and the samkhya yoga philosophy, the Gita is set in a narrative framework of dialogue between the Pandava prince Arjuna and his charioteer guide Krishna, an avatar of Vishnu, at the onset of the Kurukshetra War.

Dhyāna (Sanskrit: ध्यान) in Hinduism means meditation and contemplation. Dhyana is taken up in Yoga practices, and is a means to samadhi and self-knowledge.

The various concepts of dhyana and its practice originated in the Sramanic movement of ancient India, which started before the 6th century BCE (pre-Buddha, pre-Mahavira), and the practice has been influential within the diverse traditions of Hinduism. It is, in Hinduism, a part of a self-directed awareness and unifying Yoga process by which the yogi realizes Self (Atman, soul), one's relationship with other living beings, and the Ultimate Reality. Dhyana is also part of other Indian religions such as Buddhism and Jainism. Several other traditions introduce unique aspects and context to Dhyana, and mutually influence each other.

Yoga philosophy is one of the six major important schools of Hindu philosophy, 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 modern literature often simply call Yoga philosophy 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.

The metaphysics of Yoga is Samkhya's dualism, in which the universe is conceptualized as composed of two realities: Puruṣa (witness-consciousness) and Prakṛti (nature). Jiva (a living being) is considered as a state in which puruṣa is bonded to Prakṛti in some form, in various permutations and combinations of various elements, senses, feelings, activity and mind. During the state of imbalance or ignorance, one or more constituents overwhelm the others, creating a form of bondage. The end of this bondage is called liberation, or mokṣa, by both the Yoga and Samkhya schools of Hinduism, and can be attained by insight and self-restraint.

Hindu deities are the gods and goddesses in Hinduism. Deities in Hinduism are as diverse as its traditions, and a Hindu can choose to be polytheistic, pantheistic, monotheistic, monistic, even agnostic, atheistic, or humanist. The terms and epithets for deities within the diverse traditions of Hinduism vary, and include Deva, Devi, Ishvara, Ishvari, Bhagavān and Bhagavati.

The deities of Hinduism have evolved from the Vedic era (2nd millennium BCE) through the medieval era (1st millennium CE), regionally within Nepal, Pakistan, India and in Southeast Asia, and across Hinduism's diverse traditions. The Hindu deity concept varies from a personal god as in Yoga school of Hindu philosophy, to thirty-three major deities in the Vedas, to hundreds of deities mentioned in the Puranas of Hinduism. Examples of contemporary major deities include Vishnu, Shiva and Devi. These deities have distinct and complex personalities, yet are often viewed as aspects of the same Ultimate Reality called Brahman. From ancient times, the idea of equivalence has been cherished for all Hindus, in its texts and in early 1st-millennium sculpture with concepts such as Harihara (Half Vishnu, Half Shiva) and Ardhanārīshvara (half Shiva, half Parvati), with myths and temples that feature them together, declaring they are the same. Major deities have inspired their own Hindu traditions, such as Vaishnavism, Shaivism and Shaktism, but with shared mythology, ritual grammar, theosophy, axiology and polycentrism. Some Hindu traditions, such as Smartism from the mid 1st millennium CE, have included multiple major deities as henotheistic manifestations of Saguna Brahman, and as a means to realizing Nirguna Brahman. In Samkhya philosophy, Devata or deities are considered as "natural sources of energy" who have Sattva as the dominant Guna.

Inner peace (also known as peace of mind) refers to a deliberate state of psychological or spiritual calm maintained despite the presence of stressors. It is associated with a state of psychological "homeostasis" and the opposite of being stressed or anxious, and is considered to be a state where one's mind performs at an optimal level, regardless of outcomes. Peace of mind is thus generally associated with a state of contentment and emotional well-being including bliss, happiness and contentment.

Peace of mind, serenity, and calmness are descriptions of a disposition free from the effects of stress. In various cultural traditions, inner peace is regarded as a state of consciousness attainable through practices such as breathing exercises, prayer, meditation, tai chi or yoga. Many spiritual practices refer to this peace as an experience of knowing oneself.

The Universal White Brotherhood (UWB) is a religious movement founded in Bulgaria in 1897 by Peter Dunov. It was later established in France in 1937 by Omraam Mikhaël Aïvanhov, one of Deunov's followers.

Their teachings are also known as "Dunovism", after the founder. The group proposes a Christian esoterism, characterized by a number of practices, including prayers, meditation, breathing exercises, yoga of nutrition and paneurhythmy. A person can be both a member of the group and of another religion. It has two centers located in Sèvres and Fréjus and 2,000 followers in France. It is present in many countries, including Canada, Switzerland and Belgium.

Ayurveda (/ˌɑːjʊərˈveɪdə, -ˈviː-/; IAST: āyurveda) is an alternative medicine system with historical roots in the Indian subcontinent. It is heavily practised throughout India and Nepal, where as much as 80% of the population report using ayurveda. The theory and practice of ayurveda is pseudoscientific and toxic metals, including lead and mercury, are used as ingredients in many ayurvedic medicines.

Ayurveda therapies have varied and evolved over more than two millennia. Therapies include herbal medicines, special diets, meditation, yoga, massage, laxatives, enemas, and medical oils. Ayurvedic preparations are typically based on complex herbal compounds, minerals, and metal substances (perhaps under the influence of early Indian alchemy or rasashastra). Ancient ayurveda texts also taught surgical techniques, including rhinoplasty, lithotomy, sutures, cataract surgery, and the extraction of foreign objects.

The Bhagavata Purana (Sanskrit: भागवतपुराण; IAST: Bhāgavata Purāṇa), also known as the Srimad Bhagavatam (Śrīmad Bhāgavatam), Srimad Bhagavata Mahapurana (Śrīmad Bhāgavata Mahāpurāṇa) or simply Bhagavata (Bhāgavata), is one of Hinduism's eighteen major popular Puranas (Mahapuranas) and central text in Vaishnavism. Composed in Sanskrit and traditionally attributed to Veda Vyasa, it promotes bhakti (devotion) towards god Vishnu. Like other Puranas, it discusses a wide range of topics including cosmology, astronomy, genealogy, geography, legend, music, dance, yoga and culture.

The text consists of twelve books (skandhas or cantos) totalling 335 chapters (adhyayas) and 18,000 verses. The tenth book, with about 4,000 verses, has been the most popular and widely studied. It is widely available in almost all Indian languages and was the first Purana to be translated into a European language, as a French translation of a Tamil version appeared in 1788 and introduced many Europeans to Hinduism and 18th-century Hindu culture during the colonial era.

Entheogens are psychoactive substances used in spiritual, religious, recreational, therapeutic, and experimental contexts to induce altered states of consciousness. While the term itself emphasizes ritual and sacred applications, the same substances are also frequently employed recreationally—sometimes in ways that diverge from or disregard traditional protocols. Hallucinogens such as the psilocybin found in so-called "magic" mushrooms have been used in sacred contexts since ancient times. Derived from a term meaning "generating the divine from within", entheogens are, in religious and shamanic contexts, intentionally employed in the attempt to facilitate experiences of transcendence, healing, divination, and mystical insight.

Entheogens have been used in religious rituals in the belief they aid personal spiritual development. Anthropological study has established that entheogens are used for religious, magical, shamanic, or spiritual purposes in many parts of the world. Civilizations such as the Maya and Aztecs used psilocybin mushrooms, peyote, and morning glory seeds in ceremonies meant to connect with deities and perform healing. They have traditionally been used to supplement diverse practices, such as transcendence, including healing, divination, meditation, yoga, sensory deprivation, asceticism, prayer, trance, rituals, chanting, imitation of sounds, hymns like peyote songs, drumming, and ecstatic dance.

Tantra (/ˈtʌntrə/; Sanskrit: तन्त्र, lit. 'expansion-device, salvation-spreader; loom, weave, warp') is an esoteric yogic tradition that developed on the Indian subcontinent beginning in the middle of the 1st millennium CE, initially within Shaivism and Shaktism, and subsequently in Mahayana Buddhism, Vaishnavism. The Tantras focus on sādhana, encompassing dīkṣā, rituals, and yoga, within a ritual framework that includes bodily purification, divine self-creation through mantra, dhyāna, pūjā, mudrā, mantra recitation, and the use of yantras or maṇḍalas, despite variations in deities and mantras. They present complex cosmologies, viewing the body as divine and typically reflecting the union of Shiva and Shakti as the path to liberation. Tantric goals include siddhi (supernatural accomplishment), bhoga (worldly enjoyment), and Kuṇḍalinī’s ascent, while also addressing states of possession (āveśa) and exorcism.

The term tantra, in the Indian traditions, also means any systematic broadly applicable "text, theory, system, method, instrument, technique or practice". A key feature of these traditions is the use of mantras, and thus they are commonly referred to as Mantramārga ("Path of Mantra") in Hinduism or Mantrayāna ("Mantra Vehicle") and Guhyamantra ("Secret Mantra") in Buddhism.

A yogi is a practitioner of Yoga, including a sannyasin or practitioner of meditation in Indian religions. The feminine form, sometimes used in English, is yogini.

Yogi has since the 12th century CE also denoted members of the Nath siddha tradition of Hinduism, and in Hinduism, Buddhism and Jainism, a practitioner of tantra. In Hindu mythology, the god Shiva and the goddess Parvati are depicted as an emblematic yogi–yogini pair.

Lotus position or Padmasana (Sanskrit: पद्मासन, romanized: padmāsana) is a cross-legged sitting meditation pose from ancient India, in which each foot is placed on the opposite thigh. It is an ancient asana in yoga, predating hatha yoga, and is widely used for meditation in Hindu, Tantra, Jain, and Buddhist traditions.

Variations include easy pose (Sukhasana), half lotus, bound lotus, and psychic union pose. Advanced variations of several other asanas including yoga headstand have the legs in lotus or half lotus. The pose can be uncomfortable for people not used to sitting on the floor, and attempts to force the legs into position can injure the knees.

The Yoga Sutras of Patañjali (IAST: Patañjali yoga-sūtra) is a compilation "from a variety of sources" of Sanskrit sutras (aphorisms) on the practice of yoga – 195 sutras (according to Vyāsa and Krishnamacharya) and 196 sutras (according to others, including BKS Iyengar). The Yoga Sutras were compiled in India in the early centuries CE by the sage Patanjali, who collected and organized knowledge about yoga from Samkhya, Buddhism, and older Yoga traditions, and possibly another compiler who may have added the fourth chapter. He may also be the author of the Yogabhashya, a commentary on the Yoga Sutras, traditionally attributed to the legendary Vedic sage Vyasa, but possibly forming a joint work of Patanjali called the Pātañjalayogaśāstra.

The Yoga Sutras draw from three distinct traditions from the 2nd century BCE to the 1st century CE, namely Samkhya, Buddhism traditions, and "various older ascetic and religious strands of speculation." The Yoga Sutras are built on Samkhya notions of purusha and prakriti, and are often seen as complementary to it. It is closely related to Buddhism, incorporating some of its terminology. While there is "an apparent lack of unity and coherence," there is a "straightforward unity to the text," which focuses on "one-pointed awareness" (ekagrata) and "content-free awareness" (nirvikalpa samadhi); the means to acquire these, namely kriya yoga ("action yoga") and ashtanga yoga (eight-limb yoga); the results acquired from the attainment of these levels of awareness; and the final goal of yoga, namely kaivalya and liberation.

Hatha yoga (/ˈhʌtə, ˈhɑːtə/; Sanskrit हठयोग, IAST: haṭhayoga) is a branch of yoga that uses physical techniques to try to preserve and channel vital force or energy. The Sanskrit word हठ haṭha literally means "force", alluding to a system of physical techniques. Some hatha yoga style techniques can be traced back at least to the 1st-century CE, in texts such as the Hindu Sanskrit epics and Buddhism's Pali canon. The oldest dated text so far found to describe hatha yoga, the 11th-century Amṛtasiddhi, comes from a tantric Buddhist milieu. The oldest texts to use the terminology of hatha are also Vajrayana Buddhist. Hindu hatha yoga texts appear from the 11th century onward.

Some of the early hatha yoga texts (11th-13th c.) describe methods to raise and conserve bindu (vital force, that is, semen, and in women rajas – menstrual fluid). This was seen as the physical essence of life that was constantly dripping down from the head and being lost. Two early hatha yoga techniques sought to either physically reverse this process of dripping by using gravity to trap the bindhu in inverted postures like viparītakaraṇī, or force bindu upwards through the central channel by directing the breath flow into the centre channel using mudras (yogic seals, not to be confused with hand mudras, which are gestures).
