The Mahavakyas: The Great Sayings of the Upanishads
Written and reviewed by The Kriya Yogi · Updated 25 September 2026
The Mahavakyas are four specific declarations found in the Upanishads that condense the entire Vedantic philosophy into powerful, meditational formulas.
The short answers
- Prajnanam Brahma (Consciousness is Brahman)
- Ayam Atma Brahma (This Self is Brahman)
- Tat Tvam Asi (Thou Art That)
- Aham Brahmasmi (I am Brahman)
Formulas for Realization
These sayings are not merely information; they are tools for contemplation intended to trigger a shift in awareness. They originate from each of the four Vedas.
The Four Great Sayings
- Prajnanam Brahma (Aitareya Upanishad, Rig Veda): The nature of the ultimate reality is pure consciousness.
- Ayam Atma Brahma (Mandukya Upanishad, Atharva Veda): This very self within me is that same ultimate reality.
- Tat Tvam Asi (Chandogya Upanishad, Sama Veda): You are That. The individual and the universal are not separate.
- Aham Brahmasmi (Brihadaranyaka Upanishad, Yajur Veda): I am Brahman. The final realization of the seeker.
