“Prajnanam Brahma” is one of the four mahavakyas, which are considered to be the most important and profound statements of the Upanishads in Advaita Vedanta. The phrase is a sanskrit sentence which translates to “Prajñānam (Consciousness) is Brahman”. It states that consciousness is the ultimate reality, the ultimate truth and that Brahman, the ultimate consciousness is the ultimate reality.

The statement is found in the Aitareya Upanishad, and it is considered to be the most succinct expression of the ultimate truth of Advaita Vedanta. It asserts that Brahman, the ultimate reality, is the same as the individual consciousness, and that the individual consciousness is a reflection of the ultimate consciousness.

The statement suggests that the true nature of the self, is pure consciousness and not the ego or body. It also implies that the ultimate reality is non-dual, meaning it is not made up of distinct parts or entities. This statement is considered as the most fundamental statement of non-dualism of Advaita philosophy and considered as the key to ultimate realization or self-realization in Advaita Vedanta.

In Advaita Vedanta, understanding and realizing the meaning of this statement is said to lead to liberation.

In Advaita Vedanta, the “four mahavakyas” are considered to be the four most important and profound statements of the Upanishads that reveal the ultimate nature of reality and the self. The four mahavakyas are:

1. “Prajnanam Brahma” or “Brahman is consciousness”: This statement, found in the Aitareya Upanishad, asserts that consciousness is the fundamental reality, the ultimate truth and that Brahman is the ultimate consciousness, the ultimate reality.
2. “Aham Brahmasmi” or “I am Brahman”: This statement, found in the Brihadaranyaka Upanishad, asserts that the individual self is not separate from the ultimate reality, but is itself the ultimate reality, Brahman.
3. “Tat Tvam Asi” or “That Thou Art”: This statement, found in the Chandogya Upanishad, asserts that the individual self and the ultimate reality, Brahman, are identical.
4. “Ayam Atma Brahma” or “This Self is Brahman”: This statement, found in the Mandukya Upanishad, asserts that the individual self and Brahman are one and the same, and that the self is a reflection of the ultimate reality.
   These statements are considered to be some of the most important and profound teachings of Advaita Vedanta and are studied and meditated upon.
