It's a key concept in Advaita Vedanta, a school of Hindu philosophy that emphasizes the oneness of the ultimate reality (Brahman) and the individual soul (Atman).
Here's a breakdown:
* Advaita: means "not two" or "non-dual"
* Vedanta: refers to the end of the Vedas, a collection of ancient Hindu scriptures.
Therefore, adwaitham signifies the ultimate unity of all existence, negating the separation between the individual self and the divine.
