Atman (Hinduism) in the context of "Punarjanman"

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.

A traditional Vedic 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. (though there are exceptions to the latter two: Mimamsa and Samkhya respectively).

Sassatavada (Pali), also śāśvata-dṛṣṭi (Sanskrit), usually translated "eternalism", is a kind of thinking rejected by the Buddha in the nikayas (and agamas). One example of it is the belief that the individual has an unchanging self. Views of this kind were held at the Buddha's time by a variety of groups.

The Buddha rejected this and the opposite concept of ucchedavada (annihilationism) on both logical and epistemic grounds. He proposed a Middle Way between these extremes, relying not on ontology but on causality.

Maya (/ˈmɑːjə/; Devanagari: माया; IPA: [mɑː.jɑ́ː]; IAST: māyā), literally "illusion" or "magic", has multiple meanings in Indian philosophies depending on the context. In later Vedic texts, māyā connotes a "magic show, an illusion where things appear to be present but are not what they seem"; the principle which shows "attributeless Absolute" as having "attributes". Māyā also connotes that which "is constantly changing and thus is spiritually unreal" (in opposition to an unchanging Absolute, or Brahman), and therefore "conceals the true character of spiritual reality".

In the Advaita Vedanta school of Hindu philosophy, māyā, "appearance", is "the powerful force that creates the cosmic illusion that the phenomenal world is real". In this nondualist school, māyā at the individual level appears as the lack of knowledge (avidyā) of the real Self, Atman-Brahman, mistakenly identifying with the body-mind complex and its entanglements.

Ishvara (Sanskrit: ईश्वर, romanized: Īśvara) 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 lord, ruler, king, husband, queen, soul or the Supreme Self (Paramatman). 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 like 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 (Saguna brahman).

In Buddhism, the term anattā (Pali: 𑀅𑀦𑀢𑁆𑀢𑀸) is the doctrine of "non-self" – that no unchanging, permanent self exists, and is the absence of essence in any phenomenon. While often interpreted as a doctrine denying the existence of a self, anatman is more accurately described as a strategy to attain non-attachment by recognizing everything as impermanent, while staying silent on the ultimate existence of an unchanging essence. In contrast, dominant schools of Hinduism assert the existence of Ātman as pure awareness or witness-consciousness, "reify[ing] consciousness as an eternal self".

The Kaivalya Upanishad (Sanskrit: कैवल्य उपनिषद्) is a late 1st millennium BCE Sanskrit text and one of the minor Upanishads of Hinduism. It is classified as a Shaiva Upanishad, and survives into modern times in two versions, one attached to the Krishna Yajurveda and other attached to the Atharvaveda. It is, as an Upanishad, a part of the corpus of Vedanta literature collection that presents the philosophical concepts of Hinduism.

The Upanishad extols Shiva, aloneness and renunciation, describes the inner state of man in his personal spiritual journey detached from the world. The text is notable for presenting Shaivism in Vedanta, discussing Atman (Self) and its relation to Brahman, and Self-knowledge as the path to kaivalya (liberation).
