What is Keno Upanishad ?
The Keno Upanishad is an ancient Indian spiritual text that belongs to the Sama Veda tradition. It is one of the primary Upanishads, also known as Mukhya Upanishads. The name “Keno” comes from the first word of the text, which means “by whom”. The Keno Upanishad asks deep questions about the source of our consciousness and life. It investigates:
- By whom is the mind directed?
- Who makes the body live?
- What power enables us to see, hear, and think?
The answer it gives is Brahman, the Supreme Reality. Everything in the universe works because of Brahman, but Brahman itself is beyond the reach of the senses and intellect.
Key Teachings of Keno Upanishad
- Brahman is the power behind all senses and actions.
- Brahman is beyond the mind, speech, and senses.
- True knowledge is realizing Brahman within yourself.
- Humility is essential—power comes from Brahman, not from ego.
- The Self (Atman) is one with Brahman.
The Keno Upanishad teaches that Brahman is the unseen power behind all life and knowledge, and realizing this truth leads to self-awareness and liberation.

Shankaracharya’s Teachings on Brahman in the Keno Upanishad
Shankaracharya uses the Keno Upanishad to teach that realizing Brahman as your true Self leads to liberation (moksha), and that Brahman is beyond all sense perception but is the essence of everything.
- Brahman is the source and support of all actions, senses, and thoughts, yet it is beyond human perception and intellect.
- You cannot know Brahman through ordinary means (like sight, hearing, or thinking); it can only be realized through direct experience in deep meditation and self-inquiry.
- Shankara emphasizes Advaita (non-duality)—there is no difference between the individual self (Atman) and Brahman, the supreme reality.
- He reminds us that ego and pride (like those shown by the gods in the story) are illusions; true power and knowledge belong to Brahman alone.
