Summary

śloka 128 of Vivekacūḍāmaṇi

Ācārya Tadany began the class by reciting and introducing śloka 128 from Vivekacūḍāmaṇi:

yena viśvam idaṃ vyāptaṃ

yaṃ na vyāpnoti kiñcana

ābhā-rūpam idaṃ sarvaṃ

yam bhāntyanubhātyayam

Ācārya Tadany noted that there are two possible readings in the third line:

ābhā-rūpam or abhā-rūpam.

Both readings are acceptable and found in different source texts.

 

The Pronoun “Ayam” and Ever-Evident Consciousness

Ācārya Tadany explained the significance of the pronoun ayam (this) used in the śloka. In Sanskrit, pronouns indicate degrees of distance from the subject:

• saḥ — that (farthest)
• eṣaḥ — this (moderately distant)
• ayam — this (nearest, most evident)

The use of ayam for Ātman indicates that consciousness is the most evident, nearest reality — it is nitya svayaṃ prakāśa rūpaḥ (eternally self-evident).

Key distinction: While external objects like a glass require sense organs (eyes must be open and directed toward the object) to be evident, consciousness requires no sense organs at all. Whether eyes are open or closed, consciousness remains evident:

• Eyes open → consciousness is evident as the illuminator of forms, colors, and shapes
• Eyes closed → consciousness is evident as the illuminator of the absence of forms, colors, and shapes

This applies to all sense experiences: presence or absence of sound, touch, smell, taste — consciousness illumines both states. Therefore, consciousness is ayam — ever-evident, requiring no conditions.

Important question: When is consciousness evident? The answer: consciousness is always evident. The correct counter-question is: “When is consciousness not evident?”

 

Consciousness as All-Pervading (Vyāpti)

The first line of the śloka states: yena viśvam idaṃ vyāptam — “by which this entire universe is pervaded.”

Ācārya Tadany emphasized that this teaching is unique to Vedānta. Not only is consciousness independent (satyam), but it is also all-pervading — it pervades the entire universe (idam viśvam vyāptam).

The second line confirms: yaṃ na vyāpnoti kiñcana — “nothing pervades consciousness.” This is logically necessary because the pervader must be larger than the pervaded. Just as a blanket must be larger than the body it covers, consciousness must be larger than everything it pervades. Therefore, nothing can be larger than or pervade consciousness.

 

Common Misconception: Consciousness Located Within the Body

Ācārya Tadany addressed a very common mistake that students make, even after studying Vedānta for some time.

The mistake: When we define consciousness as the “witness of thoughts,” we naturally conclude that consciousness must be located within the body. This is because:

• Thoughts occur in the mind
• The mind is (mistakenly) assumed to be located in the body
• Therefore, consciousness (witness of thoughts) must be inside the body

This misconception is reinforced by:

• Scientific understanding that consciousness exists only where there is a brain, neurons, or cells
• Some Upaniṣadic statements that instruct seekers to “turn within” (antarmukhī bhava)

While these teachings have pedagogical value for introductory understanding, Śaṅkarācārya wants to correct this limited view. Consciousness is not confined to the body — it is all-pervading.

 

Manifest (Vyakta) vs Unmanifest (Avyakta) Consciousness

The natural question arises: If consciousness is all-pervading, why don’t we recognize consciousness everywhere? Why do we experience consciousness only in living beings and not in objects like a glass or book?

Ācārya Tadany provided the answer from Ātmabodha and Bhagavad Gītā:

sadā sarvagataṃ cāpi nātmā sarvatr dṛśyate

buddhau eva tu dṛśyate sūkṣmatvāt kūṭastha-nityaḥ

“Even though Ātman is present everywhere, it is not perceived everywhere. It is perceived only in the intellect (buddhi), just as a reflection is seen only in a clear mirror.”

Key teaching: The recognition of consciousness requires an appropriate medium. This is not a limitation of consciousness itself, but a limitation of manifestation — and in fact, our limitation.

Two helpful analogies:

• Electricity analogy: Electricity flows through all wires in your house right now, but you recognize its presence only when you turn on a light switch or fan. The electricity is present everywhere in the wiring, but manifestation requires a specific device (bulb, fan, etc.).
• Light reflection analogy: Light from your face travels in all directions. If you hold a book in front of your face, light reflects off the book, but you cannot see your face. If you hold a mirror, you see your reflection. The light is present in both cases, but recognition requires an appropriate medium (mirror).

Technical terms:

• Vyakta caitanyam (manifest consciousness) — consciousness recognized in living beings with appropriate medium (body-mind complex)
• Avyakta caitanyam (unmanifest consciousness) — consciousness present everywhere but not recognized due to lack of appropriate medium

 

How to Recognize Consciousness Everywhere

Ācārya Tadany introduced an indirect method taught in Vedānta for recognizing consciousness everywhere (both vyakta and avyakta caitanyam):

1. Study śāstra thoroughly until you come to the firm, doubtless conclusion that consciousness alone exists
2. Understand that consciousness and existence are one and the same — therefore, the recognition of existence equals the recognition of consciousness
3. Recognize consciousness in all objects as existence itself

Practical example: How do we recognize consciousness in a glass?

• We cannot recognize consciousness in the glass as consciousness (it is avyakta, unmanifest)
• But we recognize consciousness in the glass as existence
• When we say “the glass is” or “the book is,” we are acknowledging existence
• Where existence is, consciousness is — they are non-different

Counter-question method:

• Question: “Where is existence?”
• Answer: Counter with “Where is existence not?”

This applies even to the farthest star in the universe — we recognize consciousness in that star as its existence. As the teaching states: yaśaiva supūrṇaṃ sad ātmakaṃ asat kalpārthakaṃ bhāsate — “Eternally shining consciousness illumines even the unmanifest (asat) and gives it meaning and substance.”

Ācārya Tadany noted this is a critical side topic that fundamentally changes how we perceive reality and everything in the universe.

 

Definition of Cetanam vs Acetanam/Jaḍam

The third line of the śloka uses the term ābhā-rūpam (or abhā-rūpam), where:

• ābhā = caitanyam (consciousness)
• abhā = acetanam (non-consciousness)

Therefore, abhā-rūpam = acetana-rūpam = jaḍa-rūpam (insentient nature)

Critical Vedāntic definitions:

Cetanam (consciousness): That which can prove its existence by itself

• Self-evident, self-proving
• Does not require pramāṇa (means of knowledge) to establish its existence
• Example: “Am I here right now?” — No need for pratyakṣa (perception), anumāna (inference), or any logical proof. I already know I exist before any thinking or recognition occurs.

Acetanam/Jaḍam (non-consciousness): That which cannot prove its existence by itself

• Inert, insentient
• Requires consciousness to prove its existence
• Examples: glass, book, body — none can prove their own existence

Fundamental principle: The existence of any object (book, glass, picture) is proved only by the self-evident consciousness (I, the witness). Without consciousness, no object can prove its existence.

Practical application: “I do not have horns on my head.” How can we say this with certainty? Because horns are not available for any proof — they do not fall within consciousness in past, present, or future. If something does not fall within consciousness in any of the three periods of time, it is non-existent.

Ācārya Tadany gave a humorous example: After class, if you tell your family “there was a blue elephant next to Guruji during class,” and they ask for proof, you cannot simply say “I don’t need to prove it, I know it was there.” They would question your participation in Vedānta classes!

Why? Because the existence of anything is acceptable only when it falls within consciousness — past, present, or future.

This principle even applies to astronomy: We accept the existence of distant stars and galaxies not currently within our consciousness because they will fall within consciousness in the future (through telescopes, etc.). But if something does not fall within consciousness in any time period, it is non-existent.

 

Self-Proving vs Dependently Proven Existence

The fourth line of the śloka states: yam bhānty anubhāty ayam

Two key terms:

• Bhāti — shines independently, self-luminous
• Anubhāti — shines dependently, derives its shine from another

The teaching:

• Ābhā-rūpam (cetanam/consciousness) is bhāti — it shines independently, proves its own existence directly
• Abhā-rūpam (acetanam/jaḍam) is anubhāti — it shines dependently, proves its existence only indirectly through consciousness

The entire acetana-prapañca (universe of insentient objects) reveals its existence only indirectly (anubhāti) — behind, dependent upon, and because of Ātman (consciousness).

Final summary:

• Consciousness (caitanyam/ābhā-rūpam) is self-proving — bhāti
• Everything else (acetanam/jaḍam/abhā-rūpam) is dependently proven — anubhāti
• Without consciousness, the entire universe of insentient objects would have no proof of existence
