In Hinduism and Advaita Vedanta philosophy, Atman and Brahman are two fundamental concepts that are central to understanding the nature of reality and the human experience.

Atman refers to the individual soul, which is seen as an eternal, unchanging, and indestructible essence that is present in every living being. According to Advaita Vedanta, the Atman is not separate from the ultimate reality of Brahman but is a manifestation of it.

Brahman, on the other hand, refers to the ultimate reality and is seen as the source and foundation of all existence. Brahman is described as pure consciousness, beyond all concepts and attributes, including time and space. According to Advaita Vedanta, Brahman is the only true reality, and everything else, including the physical world and the individual self, is an illusion (Maya).

t is believed that through a process of self-inquiry and contemplation, one can realize the ultimate reality of Brahman and the identity of the individual self with the ultimate reality. This realization is seen as the ultimate goal of human existence and is often referred to as enlightenment or liberation.
