The Upanishads are a collection of sacred texts that are considered to be the foundation of Hinduism. They contain the teachings of the ancient sages and seers who realized the ultimate truth of Brahman.

Moksha is the ultimate goal of the Vedanta Philosophy. It is the state of liberation from the cycle of birth and rebirth, and the attainment of the highest reality, Brahman.

Brahman is the ultimate reality, the source of all that exists. It is infinite, eternal, and unchanging.

Brahman and Atman are one and the same. The Atman is the individual soul, and the Brahman is the universal soul. They are both the same essence.

Self-realization is the path to moksha. It is the realization of the true nature of the self, which is Brahman.

The guru plays an important role in the Vedanta Philosophy. He teaches the student the scriptures, guides the student on the path to moksha, and helps the student overcome obstacles.

The four main schools of Vedanta Philosophy are Advaita Vedanta, Dvaita Vedanta, Vishishtadvaita Vedanta, and Bhedabheda Vedanta.

The main teaching of Advaita Vedanta is that Brahman is the only reality, the world is an illusion, and the Atman is identical to Brahman.

Madhvacharya is considered to be the founder of Dvaita Vedanta.

The main teaching of Dvaita Vedanta is that Brahman and Atman are different, the world is real, and Bhakti is the path to moksha.

Ramanuja is considered to be the founder of Vishishtadvaita Vedanta.

The main teaching of Vishishtadvaita Vedanta is that Brahman is the only reality, the world is real, and the Atman is a part of Brahman.
