Sakshi (Witness) in the context of "Advaita Vedanta"

Ātman (/ˈɑːtmən/; Sanskrit: आत्मन्) 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-image or ego (Ahamkara), the emotional aspect of the mind (Citta), and the bodily or natural aspects (prakṛti). The term is often translated as soul, but is better translated as "Self" or essence. To attain moksha (liberation), a human being must acquire self-knowledge (Atma Gyaan or Brahmajnana).

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 (sakshi), 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 (Jīv)Atman and the supreme Self (Paramātmā) or Ultimate Reality (Vishnu, Shiva, Brahman) are that atman and Brahman are simultaneously different and non-different (Bhedabheda), non-different (Advaita, 'not-two'), different with dependence (Dvaita, 'dualist'), or non-different but with dependence (Vishishtadvaita, qualified non-dualism).

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".
