Advaita Vedanta is a spiritual philosophy that originated in ancient India and is based on the teachings of the Upanishads, which are the final part of the Vedas, the sacred texts of Hinduism. The word "Advaita" means "non-duality" and "Vedanta" means "end of the Vedas", so Advaita Vedanta can be translated as "the end of duality". It is a non-dualistic philosophy that teaches that the ultimate reality is one, and that everything in the universe is a manifestation of this one reality.

Mooji, also known as Anthony Paul Moo-Young, is a spiritual teacher who follows the path of Advaita Vedanta. He was born in Jamaica and spent many years studying different spiritual traditions before meeting his teacher, Papaji, who introduced him to the teachings of Advaita Vedanta. Mooji's teachings are rooted in the non-dualistic understanding that all beings are ultimately one with the divine.

Mooji teaches Advaita Vedanta through the practice of self-inquiry, which involves questioning the nature of one's true self. He encourages his students to go beyond their thoughts, emotions, and identities, and to discover the true essence of their being. This is done through a process of self-examination and introspection, where one becomes aware of the mind's constant chatter and learns to detach from it.

Mooji also emphasizes the importance of being present in the moment and letting go of attachments to the past and future. He teaches that the present moment is the only reality and that by focusing on it, one can experience a sense of peace and freedom from the mind's constant fluctuations.

One of the key teachings of Advaita Vedanta is the concept of "neti-neti", which means "not this, not that". This is the process of negating all that is not the true self, in order to discover what is beyond the mind and body. Mooji guides his students through this process of self-inquiry, encouraging them to let go of all concepts and beliefs and to simply be present in the awareness of their own being.

Mooji's teachings are also deeply rooted in the understanding of the impermanence of all things. He reminds his students that everything in the world, including our thoughts, emotions, and identities, is constantly changing and therefore cannot be our true self. By letting go of these temporary aspects of ourselves, we can discover the eternal and unchanging essence of our being.

In conclusion, Advaita Vedanta is a philosophy that teaches the ultimate reality of oneness and non-duality. Mooji teaches this philosophy through self-inquiry, being present in the moment, and letting go of attachments and concepts. His teachings guide his students towards the discovery of their true self, beyond the mind and body, and towards a state of peace and freedom.
