Hinduism 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 first expounded in the Vedas. The word Hindu is an exonym, and while Hinduism has been called the oldest religion in the world, it has also been described by the modern term Sanātana Dharma emphasizing its eternal nature. Another endonym for Hinduism is Vaidika Dharma.
Swami Vivekananda, born Narendranath Datta was an Indian Hindu monk, philosopher, author, religious teacher, and the chief disciple of the Indian mystic Ramakrishna. He was a key figure in the introduction of Vedanta and Yoga to the Western world. He is credited with raising interfaith awareness and bringing Hinduism to the status of a major world religion in the late nineteenth century.
The Upanishads are late Vedic and post-Vedic Sanskrit texts that "document the transition from the archaic ritualism of the Veda into new religious ideas and institutions" and the emergence of the central religious concepts of Hinduism. They are the most recent addition to the Vedas, the oldest scriptures of Hinduism, and deal with meditation, philosophy, consciousness, and ontological knowledge. Earlier parts of the Vedas dealt with mantras, benedictions, rituals, ceremonies, and sacrifices.
Ātman is a Sanskrit word for the true or eternal Self or the self-existent essence or impersonal witness-consciousness within each individual. Atman is conceptually different from Jīvātman, which persists across multiple bodies and lifetimes. Some schools of Indian philosophy regard the Ātman as distinct from the material or mortal ego (Ahankara), the emotional aspect of the mind (Citta), and existence in an embodied form (Prakṛti). The term is often translated as soul, but is better translated as "Self", as it solely refers to pure consciousness or witness-consciousness, beyond identification with phenomena. In order to attain moksha (liberation), a human being must acquire self-knowledge.
Moksha, also called vimoksha, vimukti, and mukti, is a term in Jainism, Buddhism, Hinduism, and Sikhism for various forms of emancipation, liberation, nirvana, or release. In its soteriological and eschatological senses, it refers to freedom from saṃsāra, the cycle of death and rebirth. In its epistemological and psychological senses, moksha is freedom from ignorance: self-realization, self-actualization and self-knowledge.
Adi Shankara, also called Adi Shankaracharya, was an Indian Vedic scholar, philosopher and teacher (acharya) of Advaita Vedanta. Reliable information on Shankara's actual life is scanty, and his true impact lies in his "iconic representation of Hindu religion and culture," despite the fact that most Hindus do not adhere to Advaita Vedanta. He is seen by Hindus as "the one who restored the Hindu dharma against the attacks of the Buddhists and in the process helped to drive Buddhism out of India." Tradition also portrays him as the one who reconciled the various sects with the introduction of the Pañcāyatana form of worship, the simultaneous worship of five deities – Ganesha, Surya, Vishnu, Shiva and Devi, arguing that all deities were but different forms of the one Brahman, the invisible Supreme Being.
Vedanta, also known as Uttara Mīmāṃsā, is one of the six orthodox (āstika) traditions of textual exegesis and Hindu philosophy. The word Vedanta means 'conclusion of the Vedas', and encompasses the ideas that emerged from, or aligned and reinterpreted, the speculations and enumerations contained in the Upanishads, focusing, with varying emphasis on devotion and knowledge, and liberation. Vedanta developed into many traditions, all of which give their specific interpretations of a common group of texts called the Prasthānatrayī, translated as 'the three sources': the Upanishads, the Brahma Sutras, and the Bhagavad Gita.
Advaita Vedanta is a Hindu tradition of textual exegesis and philosophy which states that jivatman, the individual experiencing self, is ultimately pure awareness mistakenly identified with body and the senses, and non-different from Ātman-Brahman, the highest Self or Reality. The term Advaita literally means "non-secondness", but is usually rendered as "nonduality", and often equated with monism. It modifies the Samkhya-dualism between Purusha and Prakriti as the two equal basic principles of existence, proposing instead that Atman-Brahman alone is ultimately real, and, though unchanging, the cause and origin of the transient phenomenal world (prakriti). In this view, the jivatman or individual self is a mere reflection or limitation of singular Ātman in a multitude of apparent individual bodies. It regards the material world as an illusory appearance (maya) or "an unreal manifestation (vivarta) of Brahman," the latter as proposed by the 13th century scholar Prakasatman.
Indian philosophy consists of philosophical traditions of the Indian subcontinent. The philosophies are often called darśana meaning, "to see" or "looking at." Ānvīkṣikī means “critical inquiry” or “investigation." Unlike darśana, ānvīkṣikī was used to refer to Indian philosophies by classical Indian philosophers, such as Chanakya in the Arthaśāstra.
Jnana yoga, also known as jnanamarga, is one of the three classical paths (margas) for moksha (liberation) in the Bhagavad Gita, which emphasizes the "path of knowledge" or the "path of self-realization". The other two are karma yoga and bhakti yoga. Modern interpretations of Hindu texts have led to the a fourfold classification to include Raja yoga, that is, meditation as described in the Yoga Sutras of Patanjali.
Madhvacharya, also known as Purna Prajna and Ānanda Tīrtha, was an Indian philosopher, theologian and the chief proponent of the Dvaita (dualism) school of Vedanta. Madhva called his philosophy Tattvavāda meaning "arguments from a realist viewpoint".
Ishvara is a concept in Hinduism, with a wide range of meanings that depend on the era and the school of Hinduism. In ancient texts of Hindu philosophy, depending on the context, Ishvara can mean supreme Self, ruler, lord, king, queen or husband. In medieval era Hindu texts, depending on the school of Hinduism, Ishvara means God, Supreme Being, personal God, or special Self. In Shaivism, Ishvara is an epithet of Shiva. In Vaishnavism it is synonymous with Vishnu, like in his epithet of Venkateswara. In traditional Bhakti movements, Ishvara is one or more deities of an individual's preference (Iṣṭa-devatā) from Hinduism's polytheistic canon of deities. In modern-day sectarian movements such as Arya Samaj and Brahmoism, Ishvara takes the form of a monotheistic God. In the Yoga school of Hinduism, it is any "personal deity" or "spiritual inspiration". In Advaita Vedanta, Ishvara is the manifested form of Brahman.
The standard problem of evil found in monotheistic religions does not apply to almost all traditions of Hinduism because it does not posit an omniscient, omnipotent, omnibenevolent creator.
The Smarta tradition, also called Smartism, is a movement in Hinduism that developed and expanded with the Puranas genre of literature. It reflects a synthesis of four philosophical strands, namely Uttara Mīmāṃsā, Advaita, Yoga, and theism. The Smarta tradition rejects theistic sectarianism, and is notable for the domestic worship of five shrines with five deities, all treated as equal – Ganesha, Shiva, Shakti, Vishnu and Surya. The Smarta tradition contrasted with the older Shrauta tradition, which was based on elaborate rituals and rites. There has been a considerable overlap in the ideas and practices of the Smarta tradition with other significant historic movements within Hinduism, namely Shaivism, Brahmanism, Vaishnavism, and Shaktism.
In Hinduism, the conception of God varies in its diverse religio-philosophical traditions. Hinduism comprises a wide range of beliefs about God and Divinity, such as henotheism, monotheism, polytheism, panentheism, pantheism, pandeism, monism, agnosticism, atheism, and nontheism.
Vaishnavism is one of the major Hindu denominations along with Shaivism, Shaktism, and Smartism. It is also called Vishnuism since it considers Vishnu as the sole supreme being leading all other Hindu deities, that is, Mahavishnu. Its followers are called Vaishnavites or Vaishnavas, and it includes sub-sects like Krishnaism and Ramaism, which consider Krishna and Rama as the supreme beings respectively. According to a 2020 estimate by The World Religion Database (WRD), hosted at Boston University’s Institute on Culture, Religion and World Affairs (CURA), Vaishnavism is the largest Hindu sect, constituting about 399 million Hindus.
In Hinduism, Brahman connotes the highest universal principle, the Ultimate Reality of the universe. In major schools of Hindu philosophy, it is the non-physical, efficient, formal and final cause of all that exists. It is the pervasive, infinite, eternal truth, consciousness and bliss which does not change, yet is the cause of all changes. Brahman as a metaphysical concept refers to the single binding unity behind diversity in all that exists.
Hindu denominations, sampradayas, traditions, movements, and sects are traditions and sub-traditions within Hinduism centered on one or more gods or goddesses, such as Vishnu, Shiva, Shakti and so on. The term sampradaya is used for branches with a particular founder-guru with a particular philosophy.
Neo-Vedanta, also called Hindu modernism, neo-Hinduism, Global Hinduism and Hindu Universalism, are terms to characterize interpretations of Hinduism that developed in the 19th century. The term "Neo-Vedanta" was coined by German Indologist Paul Hacker, in a pejorative way, to distinguish modern developments from "traditional" Advaita Vedanta.
Advaita Vedānta is the oldest extant tradition of Vedānta, and one of the six orthodox (āstika) Hindu philosophies. Its history may be traced back to the start of the Common Era, but takes clear shape in the 6th-7th century CE, with the seminal works of Gaudapada, Maṇḍana Miśra, and Shankara, who is considered by tradition and Orientalist Indologists to be the most prominent exponent of the Advaita Vedānta, though the historical fame and cultural influence of Shankara grew only centuries later, particularly during the era of the Muslim invasions and consequent reign of the Indian subcontinent. The living Advaita Vedānta tradition in medieval times was influenced by, and incorporated elements from, the yogic tradition and texts like the Yoga Vasistha and the Bhagavata Purana. In the 19th century, due to the interplay between western views and Indian nationalism, Advaita came to be regarded as the paradigmatic example of Hindu spirituality, despite the numerical dominance of theistic Bkakti-oriented religiosity. In modern times, its views appear in various Neo-Vedānta movements.
