Thomas Garden referred me to this concept. I thought I should share the knowledge.
Advaita Vedanta literally, "not-duality" is a school of Hindu philosophy, and originally known as Puruṣavāda,
The term Advaita refers to the idea that the true self, Atman, is the same as the highest metaphysical reality of the universe, Brahman.
The followers of this school are known as Advaita Vedantins, or just Advaitins or Mayavadins, regarding the phenomenal world as illusory, that is, created by the sense-impressions and the mind, and they seek spiritual liberation through recognizing this illusoriness of the phenomenal world and acquiring vidyā (knowledge) of one's true identity as Atman, and the identity of Atman and Brahman.[
Advaita Vedanta traces its roots to the oldest Upanishads. It relies on three textual sources called the Prasthanatrayi. It gives "a unifying interpretation of the whole body of Upanishads", the Brahma Sutras, and the Bhagavad Gita.
Advaita Vedanta is the oldest extant sub-school of Vedanta, which is one of the six orthodox (āstika) Hindu philosophies (darśana). Although its roots trace back to the 1st millennium BCE, the most prominent exponent of the Advaita Vedanta is considered by tradition to be the 8th century scholar Adi Shankara.
Advaita Vedanta emphasizes Jivanmukti, the idea that moksha (freedom, liberation) is achievable in this life in contrast to other Indian philosophies that emphasize videhamukti, or moksha after death.
The school uses concepts such as Brahman, Atman, Maya, Avidya, meditation and others that are found in major Indian religious traditions, but interprets them in its own way for its theories of moksha. Advaita Vedanta is one of the most studied and most influential schools of classical Indian thought. Many scholars describe it as a form of monism, others describe the Advaita philosophy as non-dualistic. Advaita is considered to be philosophy or spiritual pathway rather than a religion, it does not require those who follow it to be of a particular faith or sect.
Advaita Vedanta texts espouse a spectrum of views from idealism, including illusionism, to realist or nearly realist positions expressed in the early works of Shankara. In modern times, its views appear in various Neo-Vedanta movements. It has been termed as the paradigmatic example of Hindu spirituality.
