https://en.wikipedia.org/wiki/Advaita_Vedanta
The term Advaita (literally "non-secondness", but usually rendered as "nondualism",[5][6]and often equated with monism[note 3]) refers to the idea that Brahman alone is ultimately real, while the transient phenomenal world is an illusory appearance (maya) of Brahman. In this view, jivatman, the experiencing self, is ultimately non-different ("na aparah") from Ātman-Brahman, the highest Self or Reality.[3][7][8][note 4] The jivatman or individual self is a mere reflection or limitation of singular Ātman in a multitude of apparent individual bodies.[9]
Vedanta
Vedanta (/veɪˈdɑːntə/; Sanskrit: वेदान्त, IAST: Vedānta), also known as Uttara Mīmāṃsā, is one of the six orthodox (āstika) schools of Hindu philosophy. The word "Vedanta" means "conclusion of the Vedas", and encompasses the ideas that emerged from, or were aligned with, the speculations and enumerations contained in the Upanishads, with a focus on knowledge and liberation. Vedanta developed into many schools, all of which base their ideas on the authority of a common group of texts called the Prasthānatrayī, translated as "the three sources": the Upanishads, the Brahma Sutras and the Bhagavad Gita.[1]
