Who Can Know the Knower?

The 21st mantra from the Dviteeya valli of the first chapter of Kathopanishad -

आसीनो दूरं व्रजति शयानो याति सर्वतः ।

कस्तं मदामदं देवं मदन्यो ज्ञातुमर्हति ॥ २१॥

Don’t take this mantra at face value. If you read it lightly, you’ll think it’s talking about the manas — the restless mind that hops from memory to fantasy, dream to fear. But this verse isn’t describing the mind at all.

It’s describing that which sees the mind — the Atma.

The Upanishad says:

• ‘While sitting, it travels far.’
  
  
• ‘While lying down, it moves everywhere.’
  
  

Now listen — the mind may flit about, but it is limited. It needs effort. It tires. It’s bound to the senses, to memory, to desire.

But Atma?
Atma doesn’t travel.
It doesn’t move.
It doesn’t imagine.
It simply is — present everywhere, effortlessly.

So why say ‘travels far’?
Because wherever anything is, Atma is already there — not by going, but by being. Like space — unmoving, yet present in every corner.

The mind operates within Atma.
Like waves rising in the ocean — but they are not the ocean’s full truth.
Thought is not awareness.
Dream is not the dreamer.

Atma is the witness of all this — unchanging, untouched, and ever-free.

That’s why the Upanishad calls it 'madaamadam devam' —
The Deva beyond even the pride of knowledge, beyond the intoxication of intellect.

And then the challenge:
Who can know That?
Can the eye see itself?
Can the mind, full of noise, grasp that which is silent and still?

No.

Only Atma can know Atma.
The moment you drop the ego, the intellect, the grasping — what remains is That which was always there — still, watching, present.

And that — not the wandering mind — is the real You.

• If the Atma does not move, why does the mantra describe it as traveling far and moving everywhere?
  The mantra uses these paradoxical terms to describe the Atma's omnipresence rather than its physical motion. Because the Atma is the foundational reality of all space and time, it is already present at every destination before a thought can even conceive of going there. It "travels" only in the sense that there is no place where it is absent; it is the screen upon which the movie of distance and travel is projected.
• How does the distinction between the mind and the Atma change our understanding of restlessness?
  Restlessness is a quality of the mind (manas), which is limited by energy, memory, and desire. When we identify with the mind, we feel exhausted by its constant movement. However, when we realize we are the Atma, we see that we are the silent witness of that restlessness. The Atma remains as still as the depths of the ocean, even while the surface waves of the mind are turbulent.
• What is the hidden meaning behind the phrase madaamadam devam?
  This phrase refers to the Deva (the Shining One) who is both joyful (mada) and devoid of joy (amada), or intoxicated and sober. It points to a state that transcends dualities. The Atma is the source of all bliss, yet it is not affected by the highs and lows of emotional intoxication or the dullness of depression. It is the mysterious middle ground that supports all experiences without being stained by them.
• Why is it said that the mind can never truly grasp the Atma?
  The mind is an instrument of perception that functions through division, labels, and boundaries. Since the Atma is the very subject that enables the mind to function, the mind cannot turn around and "look" at its own source. It is like a flashlight trying to shine a beam on the batteries inside itself. The mind can only know objects; it cannot "objectify" the ultimate Subject.
• If the Atma is present everywhere like space, why is it not visible to everyone?
  Visibility requires a contrast between an object and its background. Because the Atma is the universal background and has no form, color, or boundary, the outgoing senses overlook it. We are so busy looking at the "things" inside the room that we forget to notice the "space" that allows the things to exist. It remains hidden not because it is far away, but because it is too close.
• What does the Upanishad mean by the challenge: Who else but I can know this Deva?
  This is not an expression of ego, but a revelation of the only way to "know" the truth. One cannot know the Atma through a second-hand report or a book. The "I" here refers to the purified consciousness. Only when the individual ego-sense is dissolved can the Atma recognize itself. It is a knowledge by being, not a knowledge by description.
• How does the analogy of the dreamer and the dream clarify the nature of the Atma?
  In a dream, you may see mountains, people, and cities. While the dream lasts, those objects seem external and moving. However, upon waking, you realize that the entire dream world was made of nothing but your own mind, and you, the dreamer, never actually moved from your bed. Similarly, the Atma is the "dreamer" of the waking world; all movement happens within it, while it remains absolutely still.
• What is the significance of the Atma being described as "sitting" while "traveling"?
  This paradox highlights the nature of the Absolute as the Unmoved Mover. It indicates that the Atma is the stable, unchanging center of a changing universe. It "sits" in its own glory, yet because all of nature (Prakriti) is powered by its presence, every movement in the cosmos is an expression of its infinite reach.
• In what way is the Atma "beyond the pride of knowledge"?
  Human knowledge is often a source of pride (mada) because it implies an achievement of the intellect. However, the Atma is the light that illumines the intellect itself. To "know" the Atma, one must drop the pride of being a "knower." It is a state of profound humility where the seeker realizes that their intellectual brilliance is just a tiny reflection of the sun-like Atma.
• What is the practical result of realizing that the real "You" is the witness and not the wandering mind?
  The practical result is absolute fearlessness and emotional stability. If you believe you are the mind, you are a victim of every passing thought, fear, and craving. If you know you are the Atma, you understand that nothing in the world of change can add to you or take away from you. You become the "Aasina" (the Seated One)—permanently established in a peace that the world's noise cannot disturb.
