Ātman (Hinduism)
Ātman in Hinduism is the true, innermost essence or self of a living being, conceived as eternal and unchanging. Atman is conceptually closely related to the individual self, Jīvātman, which persists across multiple bodies and lifetimes, but different from the self-idea or ego, the emotional aspect of the mind, and the bodily or natural aspects. The term is often translated as soul, but is better translated as "Self" or essence. To attain moksha, a human being must acquire self-knowledge.
The six orthodox schools of Indian philosophy have different views on what this self is. In Samkhya and Yoga, which call the essence purusha, and in Advaita Vedanta, the essence is pure consciousness or witness-consciousness, beyond identification with phenomena. In Samkhya and Yoga there are innumerable selves, while in Advaita Vedanta there is only one Self. Prominent views in Vedanta on the relation between Atman and the supreme Self or Ultimate Reality are that atman and Brahman are simultaneously different and non-different, non-different, different with dependence, or non-different but with dependence, which is distinct from the body-mind complex. This is a major point of difference with the Buddhist doctrine of Anatta, which holds that in essence there is no unchanging essence or Self to be found in the empirical constituents of a living being, intentionally ambiguous on what it is that is liberated. While essentialist positions are seemingly found in Buddhism, such as in Madhyamika and Yogachara, presenting broad similarities to non-dualist traditions of Hinduism, the concept of ātman remains anathema to the foundations of Buddhism.
Etymology and meaning
Etymology
Ātman is a Sanskrit word that refers to "essence, breath, soul." It is thought to be derived from the reconstructed hypothetical Proto-Indo-European word *etmen "breath".Meaning
Olivelle notes that ātman "has many meanings and usages in the Upanisadic vocabulary," including "Self," "the ultimate essence of a human being," but is also used to refer to "a living, breathing body," and as reflexive pronoun, akin to "myself."In contemporary Hinduism, Ātman means "real Self" of the individual, "innermost essence." Atman refers to the essence of human beings that persists amid change, distinct from the ever-evolving embodied individual being embedded in material reality. Embodied personality can change while Atman does not. In Advaita Vedanta, it is the observing pure consciousness or witness-consciousness, "pure, undifferentiated, self-shining consciousness," while in Neo-Advaita it is also the nonconceptual insight that 'being' cannot be grasped in words or deeds.
While often translated as "soul", it is better translated as "self." As such, it is different from non-Hindu notions of soul, which includes consciousness but also the mental abilities of a living being, such as reason, character, feeling, consciousness, memory, perception and thinking. In Hinduism, these are all included in embodied reality, the counterpart of ''Atman.''
Development of the concept
Vedas
The earliest use of the word Ātman in Indian texts is found in the Rig Veda. Yāska, the ancient Indian grammarian, commenting on this Rigvedic verse, accepts the following meanings of Ātman: the pervading principle, the organism in which other elements are united and the ultimate sentient principle.Other hymns of Rig Veda where the word Ātman appears include I.115.1, VII.87.2, VII.101.6, VIII.3.24, IX.2.10, IX.6.8, and X.168.4.
Upanishads
Ātman is a central topic in all of the Upanishads, and "know your Ātman" is one of their thematic foci. The Upanishads say that Atman denotes "the ultimate essence of the universe" as well as "the vital breath in human beings", which is "imperishable Divine within" that is neither born nor does it die.The Upanishads express two distinct, somewhat divergent themes on the relation between Atman and Brahman. Some teach that Brahman is identical with Ātman, while others teach that Ātman is part of Brahman but not identical to it. This ancient debate flowered into various dual and non-dual theories in Hinduism. The Brahmasutra by Badarayana synthesized and unified these somewhat conflicting theories, stating that Atman and Brahman are different in some respects, particularly during the state of ignorance, but at the deepest level and in the state of self-realization, Atman and Brahman are identical, non-different. According to Koller, this synthesis countered the dualistic tradition of Samkhya-Yoga schools and realism-driven traditions of Nyaya-Vaiseshika schools, enabling it to become the foundation of Vedanta as Hinduism's most influential spiritual tradition.
The atman, according to several Upaniṣadic texts, is present within the human body, extending even to the extremities such as the tips of the nails. Though the atman pervades the entire body, the Upanishads often emphasize the heart, not as a physical organ but as an inner "cave" or guha, as the atman's special locus. It is described as lying deep within the heart.
''Brihadaranyaka Upanishad''
The Brihadaranyaka Upanishad describes Atman as that in which everything exists, which is of the highest value, which permeates everything, which is the essence of all, bliss and beyond description. In hymn 4.4.5, Brihadaranyaka Upanishad describes Atman as Brahman, and describes the self as made of everything, including the functions, elements and desires:The theme of acquiring knowledge of Brahman, and thereby becoming godlike, is extensively repeated in Brihadāranyaka Upanishad. Not even gods can prevail over such a liberated man, to their dismay. For example, in hymn 1.4.10,
''Chandogya Upanishad''
The Chandogya Upanishad explains Ātman as that which appears to be separate between two living beings but isn't, that essence and innermost, true, radiant self of all individuals which connects and unifies all. Hymn 6.10 explains it with the example of rivers, some of which flow to the east and some to the west, but ultimately all merge into the ocean and become one. In the same way, the individual souls are pure being, states the Chandogya Upanishad; an individual soul is pure truth, and an individual soul is a manifestation of the ocean of one universal soul.''Katha Upanishad''
Along with the Brihadāranyaka, all the earliest and middle Upanishads discuss Ātman as they build their theories to answer how man can achieve liberation, freedom and bliss. The Katha Upanishad explains Atman as the imminent and transcendent innermost essence of each human being and living creature, that this is one, even though the external forms of living creatures manifest in different forms. Hymn 2.2.9 states:Katha Upanishad, in Book 1, hymns 3.3-3.4, describes the widely cited proto-Samkhya analogy of chariot for the relation of "Soul, Self" to body, mind and senses. Stephen Kaplan translates these hymns as, "Know the Self as the rider in a chariot, and the body as simply the chariot. Know the intellect as the charioteer, and the mind as the reins. The senses, they say are the horses, and sense objects are the paths around them". The Katha Upanishad then declares that "when the Self understands this and is unified, integrated with body, senses and mind, is virtuous, mindful and pure, he reaches bliss, freedom and liberation".
Bhagavad Gita
In Bhagavad Gita verses 10-30 of the second chapter, Krishna urges Arjuna to understand the indestructible nature of the atman, emphasizing that it transcends the finite body it inhabits. The atman neither kills nor can be killed, as it is eternal and unaffected by birth or death. The analogy of changing clothes is used to illustrate how the soul discards old bodies for new ones. Krishna emphasizes the eternal existence of the soul by explaining that even as it undergoes various life stages and changes bodies it remains unaffected. It is imperceptible, inconceivable, and unchanging.Indian philosophy
Orthodox schools
Atman is a metaphysical and spiritual concept for Hindus, often discussed in their scriptures with the concept of Brahman. All major orthodox schools of Hinduism – Samkhya, Yoga, Nyaya, Vaisesika, Mimamsa, and Vedanta – accept the foundational premise of the Vedas and Upanishads that "Ātman exists." In Hindu philosophy, especially in the Vedanta school of Hinduism, Ātman is the first principle. Jainism too accepts this premise, although it has its own idea of what that means. In contrast, both Buddhism and the Charvakas deny that there is anything called "Ātman/soul/self".Samkhya
In Samkhya, the oldest Hindu school of Dualism, Puruṣa, the witness-consciousness, is Atman. It is absolute, independent, free, imperceptible, unknowable through other agencies, above any experience by mind or senses and beyond any words or explanations. It remains pure, "nonattributive consciousness". Puruṣa is neither produced nor does it produce. No appellations can qualify purusha, nor can it substantialized or objectified. It "cannot be reduced, can't be 'settled'." Any designation of purusha comes from prakriti, and is a limitation. Unlike Advaita Vedanta, and like Purva-Mīmāṃsā, Samkhya believes in plurality of the puruṣas.Samkhya considers ego to be the cause of pleasure and pain. Self-knowledge is the means to attain kaivalya, the separation of Atman from the body-mind complex.
Yoga philosophy
The Yogasutra of Patanjali, the foundational text of Yoga school of Hinduism, sees purusha as the essence of human beings, revealed in samadhi, but mentions Atma in multiple verses, and particularly in its last book, where Samadhi is described as the path to self-knowledge and kaivalya. Some earlier mentions of Atman in Yogasutra include verse 2.5, where evidence of ignorance includes "confusing what is not Atman as Atman".In verses 2.19-2.20, Yogasutra declares that pure ideas are the domain of Atman, the perceivable universe exists to enlighten Atman, but while Atman is pure, it may be deceived by complexities of perception or mind. These verses also set the purpose of all experience as a means to self-knowledge.
In Book 4, Yogasutra states spiritual liberation as the stage where the yogin achieves distinguishing self-knowledge, he no longer confuses his mind as Atman, the mind is no longer affected by afflictions or worries of any kind, ignorance vanishes, and "pure consciousness settles in its own pure nature".
The Yoga school is similar to the Samkhya school in its conceptual foundations of purusha as Ātman. It is the self that is discovered and realized in the Kaivalya state, in both schools. Like Samkhya, this is not a single universal Ātman. It is one of the many individual selves where each "pure consciousness settles in its own pure nature", as a unique distinct soul/self. However, Yoga school's methodology was widely influential on other schools of Hindu philosophy. Vedanta monism, for example, adopted Yoga as a means to reach Jivanmukti – self-realization in this life – as conceptualized in Advaita Vedanta. Yoga and Samkhya define Ātman as an "unrelated, attributeless, self-luminous, omnipresent entity", which is identical with consciousness.
