Tantra in the context of "Devi Upanishad"

Yoga (UK: /ˈjəʊɡə/, US: /ˈjoʊɡə/; Sanskrit: योग 'yoga' [joːɡɐ] ; lit. 'yoke' or 'union') is a group of physical, mental, and spiritual practices or disciplines that originated with its own philosophy in ancient India, aimed at controlling body and mind to attain various soteriological goals (moksha), as practiced in the Hindu, Jain, Sikh, and Buddhist traditions.

Yoga may have pre-Vedic origins, but is first attested in the early first millennium BCE. It developed as various traditions in the eastern Ganges basin drew from a common body of practices, including Vedic elements. Yoga-like practices are mentioned in the Rigveda and a number of early Upanishads, but systematic yoga concepts emerge during the fifth and sixth centuries BCE in ancient India's ascetic and Śramaṇa movements, including Jainism and Buddhism. The Yoga Sutras of Patanjali, the classical text on Hindu yoga, samkhya-based but influenced by Buddhism, dates to the early centuries of the Common Era. Hatha yoga texts began to emerge between the ninth and 11th centuries, originating in tantra.

Shaktism (Sanskrit: शाक्तसम्प्रदायः, romanized: Śāktasampradāyaḥ) is a major Hindu denomination in which the ultimate reality is considered as Adi Parashakti.

In Shaktism, the divine feminine energy, Shakti, is revered as the supreme power and is personified as the Mahadevi (Great Goddess), who manifests in numerous forms, with each form having distinct functions and unique attributes. The most prominently worshiped goddesses include Durga, the fierce protector who vanquishes evil and restores cosmic order; Parvati, the gentle yet powerful mother goddess of fertility, devotion, and spiritual wisdom; and Kali, the primal force of time and transformation. Additionally, Shaktism reveres a broader pantheon, including goddesses like Saraswati, the goddess of knowledge and arts; Lakshmi, the goddess of wealth and prosperity; and Tripura Sundari, the goddess of beauty and grace. Also honoured are the various Gramadevata, local village guardian deities, who protect and bless their communities. Following the decline of Buddhism in India, elements of Hindu and Buddhist goddess worship gradually merged, culminating in the emergence of the Mahavidya, a revered group of ten fierce and esoteric goddesses central to the tantric traditions within Shaktism.

Chamunda (Sanskrit: चामुण्डा, IAST: Cāmuṇḍā), also known as Chamundeshwari, Chamundi or Charchika, is a fearsome form of Chandi, the Hindu mother goddess, Mahadevi and is one of the seven Matrikas.

She is also one of the chief Yoginis, a group of sixty-four or eighty-one Tantric goddesses, who are attendants of the warrior goddess Parvati. The name is a combination of Chanda and Munda, two demons whom Chamunda killed. She is closely associated with Mahakali or Durga.

Guru (/ˈɡuːruː/ Sanskrit: गुरु; IAST: guru) is a Sanskrit term for a "mentor, guide, expert, or master" of certain knowledge or field. In pan-Indian traditions, a guru is more than a teacher: traditionally, the guru is a reverential figure to the disciple (or shisya in Sanskrit, literally seeker [of knowledge or truth]) or student, with the guru serving as a "counsellor, who helps mould values, shares experiential knowledge as much as literal knowledge, an exemplar in life, an inspirational source and who helps in the spiritual evolution of a student". Whatever language it is written in, Judith Simmer-Brown says that a tantric spiritual text is often codified in an obscure twilight language so that it cannot be understood by anyone without the verbal explanation of a qualified teacher, the guru. A guru is also one's spiritual guide, who helps one to discover the same potentialities that the guru has already realized.

The oldest references to the concept of guru are found in the earliest Vedic texts of Hinduism. The guru, and gurukula – a school run by guru, were an established tradition in India by the 1st millennium BCE, and these helped compose and transmit the various Vedas, the Upanishads, texts of various schools of Hindu philosophy, and post-Vedic Shastras ranging from spiritual knowledge to various arts so also specific science and technology. By about mid 1st millennium CE, archaeological and epigraphical evidence suggest numerous larger institutions of gurus existed in India, some near Hindu temples, where guru-shishya tradition helped preserve, create and transmit various fields of knowledge. These gurus led broad ranges of studies including Hindu scriptures, Buddhist texts, grammar, philosophy, martial arts, music and painting.

Tibetan Buddhism is a form of Buddhism practiced in Tibet, Bhutan and Mongolia. It also has a sizable number of adherents in the areas surrounding the Himalayas, including the Indian regions of Ladakh, Darjeeling, Sikkim, and Arunachal Pradesh, as well as in Nepal. Smaller groups of practitioners can be found in Central Asia, some regions of China such as Northeast China, Xinjiang, Inner Mongolia and some regions of Russia, such as Tuva, Buryatia, and Kalmykia.

Tibetan Buddhism evolved as a form of Mahayana Buddhism stemming from the latest stages of Buddhism (which included many Vajrayana elements). It thus preserves many Indian Buddhist tantric practices of the post-Gupta early medieval period (500–1200 CE), along with numerous native Tibetan developments. In the pre-modern era, Tibetan Buddhism spread outside of Tibet primarily due to the influence of the Mongol-led Yuan dynasty, founded by Kublai Khan, who ruled China, Mongolia, and parts of Siberia. In the Modern era, Tibetan Buddhism has spread outside of Asia because of the efforts of the Tibetan diaspora (1959 onwards). As the Dalai Lama escaped to India, the Indian subcontinent is also known for its renaissance of Tibetan Buddhism monasteries, including the rebuilding of the three major monasteries of the Gelug tradition.

Mahayana Buddhism entered Han China via the Silk Road, beginning in the 1st or 2nd century CE. The first documented translation efforts by Buddhist monks in China were in the 2nd century CE via the Kushan Empire into the Chinese territory bordering the Tarim Basin under Kanishka. These contacts transmitted strands of Sarvastivadan and Tamrashatiya Buddhism throughout the Eastern world.

Theravada Buddhism developed from the Pāli Canon in Sri Lanka Tamrashatiya school and spread throughout Southeast Asia. Meanwhile, Sarvastivada Buddhism was transmitted from North India through Central Asia to China. Direct contact between Central Asian and Chinese Buddhism continued throughout the 3rd to 7th centuries, much into the Tang period. From the 4th century onward, Chinese pilgrims like Faxian (395–414) and later Xuanzang (629–644) started to travel to northern India in order to get improved access to original scriptures. Between the 3rd and 7th centuries, parts of the land route connecting northern India with China was ruled by the Xiongnu, Han dynasty, Kushan Empire, the Hephthalite Empire, the Göktürks, and the Tang dynasty. The Indian form of Buddhist tantra (Vajrayana) reached China in the 7th century. Tibetan Buddhism was likewise established as a branch of Vajrayana, in the 8th century.

Mahayana is the largest branch of Buddhism, followed by Theravada. It is a broad group of Buddhist traditions, texts, philosophies, and practices developed in ancient India (c. 1st century BCE onwards). 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. Vajrayana or Mantra traditions are a subset of Mahāyāna which makes use of numerous Tantric methods Vajrayānists consider to help achieve Buddhahood.

Mahāyāna also refers to the path of the bodhisattva striving to become a fully awakened Buddha for the benefit of all sentient beings, and is thus also called the "Bodhisattva Vehicle" (Bodhisattvayāna). Mahāyāna Buddhism generally sees the goal of becoming a Buddha through the bodhisattva path as being available to all and sees the state of the arhat as incomplete. Mahāyāna also includes numerous Buddhas and bodhisattvas that are not found in Theravada (such as Amitābha and Vairocana). Mahāyāna Buddhist philosophy also promotes unique theories, such as the Madhyamaka theory of emptiness (śūnyatā), the Vijñānavāda ("the doctrine of consciousness" also called "mind-only"), and the Buddha-nature teaching.

Sanskrit Buddhist literature refers to Buddhist texts composed either in classical Sanskrit, in a register that has been called "Buddhist Hybrid Sanskrit" (also known as "Buddhistic Sanskrit" and "Mixed Sanskrit"), or a mixture of these two. Several non-Mahāyāna Nikāyas appear to have kept their canons in Sanskrit, the most prominent being the Sarvāstivāda school. Many Mahāyāna Sūtras and śāstras also survive in Buddhistic Sanskrit or in standard Sanskrit.

During the Indian Tantric Age (8th to the 14th century), numerous Buddhist Tantras were written in Sanskrit, sometimes interspersed with local languages like Apabhramśa, and often containing notable irregularities in grammar and meter.

A divine embodiment or godform refers to the visualized appearance of the deity assumed in theurgical, tantric, and other mystical practices. This process of ritual embodiment is aimed at transforming the practitioner, aligning them with divine powers for spiritual ascent or transformation. The concept is found across diverse traditions, including Western esotericism, Eastern spirituality, and mysticism, where it serves as a method for achieving personal enlightenment, union with the divine, or other spiritual goals.

In Western esotericism, divine embodiment is most commonly associated with theurgy, particularly in the works of Neoplatonists like Iamblichus, where the practitioner assumes a divine form through ritual or meditation to transcend the material world and reach higher spiritual realms. This concept was influenced by ancient Greek practices of invoking gods and embodying divine forces, seen in both the public cults and private rituals. The idea was later adapted and expanded in Hermeticism, particularly through the Hermetic Order of the Golden Dawn, where practitioners would visualize themselves as deities to channel spiritual power.
