Brihadaranyaka Upanishad
अहं ब्रह्मास्मि (Aham Brahmasmi)
I am Brahman - Brihadaranyaka Upanishad 1.4.10
Of the four great Mahavakyas, this is the most direct and powerful. It is not a statement to be believed, but a truth to be realized.
This teaching appears in the Brihadaranyaka Upanishad in the context of creation. The text describes how in the beginning, there was only the Self (Atman), and it looked around and saw nothing else but itself. It first uttered “I Am” (Aham Asmi), and from that came the name “I.”
Then it realized: Aham Brahmasmi—I am the totality, I am Brahman.
Not the limited ego-I, but the pure sense of existence before any qualification.
Not “I am John” or “I am a teacher”—just the bare “I AM.”
This “I” is:
सत्यं ज्ञानम् अनन्तं ब्रह्म (Satyam Jnanam Anantam Brahma)
Brahman is Truth, Knowledge, Infinite - Taittiriya Upanishad
Brahman is:
The verb “to be” in present tense, first person.
Not “was” (past) or “will be” (future)—but eternally IS.
This “am” is not becoming—it is pure being.
How can the limited “I” be the infinite Brahman?
I appear to be:
Brahman is:
The teaching points to a crucial distinction:
What you APPEAR to be (the body-mind) is not what you ARE (pure consciousness).
Just as:
So too:
A powerful reasoning to support this truth:
In waking:
In dreaming:
In deep sleep:
What remains constant across all three states?
Not the body (it’s not experienced in deep sleep)
Not the mind (it’s absent in deep sleep)
Not the world (it changes in each state)
Only awareness/consciousness remains constant—the “I” that witnesses all three states.
That “I” is Brahman.
Adi Sankara uses the example of the rope and snake:
In dim light, you see a rope and mistake it for a snake. Fear arises. When light comes, you realize it was always a rope.
Similarly:
“I am this limited person” was the ignorance.
”I am Brahman” is the knowledge that dispels that ignorance.
This is not mere philosophy. The Upanishad says:
तदात्मानमेवावेत् अहं ब्रह्मेति (Tadatmanam Evav Et Aham Brahmeti)
Therefore, know the Self as “I am Brahman”
How to know this?
Negation (Neti Neti)
Affirmation (Iti Iti)
Direct Recognition
When this truth is not just understood intellectually but realized directly:
ब्रह्मवित् ब्रह्मैव भवति (Brahmavit Brahmaiva Bhavati)
The knower of Brahman becomes Brahman - Mundaka Upanishad
Not “becomes” in the sense of transformation, but in the sense of recognition.
Like a prince raised among tribals who discovers his royal identity—he doesn’t BECOME a prince, he realizes he always WAS.
All fear ends - What can threaten the infinite?
All sorrow ends - What can limit the complete?
All seeking ends - What more could Brahman want?
The sage Vamadeva, while still in his mother’s womb, realized “Aham Brahmasmi.”
The teaching: This realization is not dependent on:
It depends only on the removal of ignorance. When the cloud of not-knowing is gone, the sun of knowledge that was always present shines forth.
Does realizing “I am Brahman” mean:
It means:
Like space—it contains all objects but is not affected by them.
There is a danger: The ego might claim “I am Brahman” and become inflated.
This is the difference between:
Ego’s claim: “I (this person) am God, I am special, worship me!”
Truth’s revelation: “There is no individual person at all—there is only Brahman appearing as all things. No one is special because everything is That.”
True realization destroys ego, not inflate it.
Aham Brahmasmi is not a belief system.
It’s not positive thinking.
It’s not spiritual ego.
It is the direct recognition of what you have always been.
Before your parents were born—you were.
When the universe dissolves—you will be.
Behind every thought, every perception, every experience—you ARE.
Not you as a person.
You as the infinite awareness.
You as Brahman itself.
पूर्णमदः पूर्णमिदं पूर्णात् पूर्णमुदच्यते
पूर्णस्य पूर्णमादाय पूर्णमेवावशिष्यतेThat is whole, this is whole. From the whole, the whole comes forth. Taking the whole from the whole, the whole alone remains - Isha Upanishad
You are that wholeness. Aham Brahmasmi.
