The Bhagavad Gītā (Chapter 2, Verse 16) declares:
“nāsato vidyate bhāvo nābhāvo vidyate sataḥ”
“The unreal has no existence; the real never ceases to be.”
This foundational insight distinguishes the ever-absent from the ever-abiding. The only reality that truly is—unchanging and independent—is existence itself, sat, or Brahman. All else—seen and unseen—arises within that one Reality and depends entirely on It.
But what then is the nature of what we perceive—the tangible world, emotions, thoughts, relationships? Is it all false?
The Reflection-Being: A Glimpse of Mithyā
To unpack this, consider your face reflected in a mirror. The reflection moves when you move, smiles when you smile. It appears expressive, consistent, and undeniably present. And yet, on deeper inspection, we realize that this “reflection-being” lacks independent existence. He depends wholly on the real face standing before the mirror.
He is not asat—completely nonexistent—for we perceive him. But he is not sat either—he cannot exist without the original. He is mithyā: an appearance with functional reality in one domain, but no ultimate substance in another.
When we inquire into the reflection-being, he disappears. What remains is sat alone. Similarly, the world, which once felt solid and autonomous, dissolves in the light of self-knowledge—revealing Brahman as the only unchanging substratum.
Climbing the Ladder of Reality
Vedānta teaches that reality comes in two levels:
- Vyāvahārika Sattā – the transactional level of daily experience, where time, cause, and individuality seem real.
- Pāramārthika Sattā – the ultimate level, where only Brahman is, and all else is sublated.
To visualize this transition, imagine a ladder.
The lower rung is vyāvahārika. It is stable enough to help us rise. Here, the world appears real, actions have results, and spiritual practice begins. The mirror-man lives here, and so does the seeker.
But as we ascend through enquiry, guided by śravaṇa, manana, and nididhyāsana, we reach the higher rung: pāramārthika. Now we no longer take the rungs for reality. We see that even the mirror and the face, the seeker and the sought, collapse into sat. The illusion of separation dissolves.
Yet, the lower rung is not false. Just as a dream has meaning until waking, or a map is helpful until the destination is reached, the empirical world has a functional reality. It is useful—but not ultimate.
Mithyā: A Gentle Disappearance
Mithyā is not a denial of the world—it is a revaluation. The world is not discarded as false but is seen as dependent: like the mirror reflection, like the movie on a screen, like the dream that evaporates but leaves learning behind.
It is not enough to intellectually accept this. The true shift comes in direct knowledge (aparokṣa jñāna), when the last rung is left behind—and the climber, the climb, and even the concept of ladders dissolve into the One.
Anirvacanīya: The Inexpressible Nature of the Illusory
In Advaita Vedānta, the term anirvacanīya means indefinable or inexpressible. This is the precise status of mithyā. The world, as we experience it, cannot be pinned down as either real (sat) or unreal (asat). It appears, functions, and dissolves—leaving us with something that defies binary categorization.
This indefinability arises because:
- If the world were real, it would never be sublated. But it does, through knowledge.
- If it were unreal, like a square circle – it would never appear. But it does appear.
Therefore, it must be something else entirely—something that appears, yet does not abide. This “something else” is anirvacanīya—a reality that is knowable only in its disappearance, like mist fading under sunlight, leaving no trace.
The term safeguards the elegance of non-duality: Brahman alone is real. The world appears through avidyā (ignorance) and is sublated through vidyā (knowledge), revealing that the entire cosmos is neither independent nor permanent—but also not nothing. It is anirvacanīya mithyā.
