From Pure Consciousness to the Expanding Cosmos
“Kasminnu bhagavo vijñāte sarvam idaṁ vijñātaṁ bhavati iti.”
— Mundaka Upanishad 1.1.3“By knowing which, everything else becomes known.”
Introduction
The question — What is that by knowing which, everything becomes known? — stands at the heart of both spiritual inquiry and scientific exploration. The exploration of Vedanta and the Big Bang sheds light on such profound questions. Understanding Vedanta and the Big Bang is crucial in this search.
In the Mundaka Upanishad, it opens the dialogue between the seeker and the sage.
In modern physics, it mirrors the quest for the Unified Field Theory — the single principle from which all forces and forms of the universe emerge.
Vedanta answers this question through the realization of Brahman, the infinite, undivided reality —
the Nirguna Brahman, pure consciousness, beyond attributes or forms. It mirrors the quest for the Unified Field Theory — the single principle from which all forces and forms of the universe emerge in Vedanta and the Big Bang.
When this infinite stillness reflects upon itself, it appears as Saguna Brahman —
the causal ground of creation, giving rise to the subtle and gross universes. Exploring Vedanta and the Big Bang can help us understand this transformation.
Philosophical Note:
The physicist and the Vedantin stand at the same threshold:
both seek the One from which the many arise.
The scientist calls it the singularity;
the sage calls it Brahman.
A Note to the Reader
This essay is meant for reflection, not speed.
It unfolds slowly — concept by concept — weaving the language of Vedanta with the precision of cosmology.
Understanding non-duality (Advaita) is not easy for the intellect.
It requires contemplation, the silence between thoughts. The concepts of Vedanta and the Big Bang can provide insights in this.
The Big Bang offers a parallel key — that all diversity emerged from an original singularity, a state beyond space and time.
What science calls the singularity, Vedanta calls Brahman — One without a second.
Because of its depth, this post may take time to absorb.
Pause between sections. Let the images, ideas, and verses settle inwardly.

The Big Bang and the Brahmanic Beginning
According to modern cosmology, (NASA: Big Bang and the Evolution of the Universe), the universe began as a singularity — infinitely dense and timeless.

For a deeper background on the scientific evolution of cosmology, read my earlier post
Cosmology: Origin of Our Universe (Part 1).
It explores how the modern model of the expanding universe parallels the ancient Vedantic view of emanation from Brahman.
According to cosmology, the universe began as a singularity —
infinitely dense, timeless, and spaceless.
At that primordial instant, all four fundamental forces — gravity, electromagnetism, strong and weak nuclear forces — were united as one.
This undivided energy field parallels the Nirguṇa Brahman of Vedanta —
the Pure Consciousness that precedes space, time, and causation (kāla, deśa, nimitta).
Just as the Big Bang marks the expansion of the universe from the singular into the manifold,
Vedanta sees the reflection of Brahman into manifestation —
not as a physical explosion, but as the vibration of Consciousness into diversity.
Philosophical Note:
“What physics calls the singularity, Vedanta names Brahman —
the stillness before space and time, where all possibilities sleep in one undivided awareness.”
The singularity before the Big Bang is not merely dense matter — it is the symbol of unmanifest potential.
In Vedanta, this state is Avyākṛta, the unmanifest, in which the entire cosmos lies folded like a tree within a seed.
The Separation of Forces in the Big Bang
“According to modern cosmology (NASA: Big Bang and the Evolution of the Universe), the universe began as a singularity — infinitely dense and timeless.”
From Unity to Multiplicity:
In both Vedanta and the Big Bang, unity precedes multiplicity; the One differentiates into many without losing its essence.
As the universe cooled, the single unified force differentiated into the four fundamental forces.
In scientific terms, this is symmetry breaking — the birth of structure and order.
Vedanta parallels this as the emanation of the five subtle elements (tanmātras) and the five great elements (mahābhūtas) from the one Consciousness.
“From that Self arose space; from space, air; from air, fire; from fire, water; from water, earth.”
— Taittiriya Upanishad 2.1
This gradual differentiation — from causal to subtle to gross —
is the unfolding of Saguna Brahman into the Sūkṣma (subtle) and Sthūla (gross) universes.
Thus, what physics describes as the separation of forces, Vedanta interprets as the manifestation of Consciousness through graded densities of reality.
Philosophical Note:
The physicist observes separation;
the sage perceives reflection.
The One remains undivided — only its expressions diversify.
This is Maya — the appearance of multiplicity upon the eternal unity of Brahman.
From Subtle Vibrations to Visible Matter — The First Three Minutes.
Here Vedanta and the Big Bang meet again — one speaks of Tanmatra, the other of quantum fields.
As differentiation continued after the primordial expansion,
the universe entered an exquisite and fragile balance.
Energy, space, and time — newly born — began their great unfolding.
Within the first fraction of a second, physics itself awakened.
🔹 The Unification Breaks — The Birth of Forces
At the moment of the Big Bang, all interactions were one — a single, unified field of immense energy and temperature, beyond comprehension.
As the universe expanded and cooled from about 10³² Kelvin downward:
-
At 10⁻⁴³ seconds (the Planck epoch): gravity separated from the other forces.
-
At 10⁻³⁶ seconds: the Grand Unified Force split — the strong nuclear force separated from the electroweak force.
-
At 10⁻¹² seconds: even the electroweak force divided into electromagnetic and weak nuclear forces.
By then, the four fundamental forces we know today — gravity, strong, weak, and electromagnetic — were distinct, setting the stage for structure and complexity.
In the language of Vedanta, this was the first stirring of Maya —
the One energy field (Brahman as Nirguna) differentiating into diverse principles (Saguna Brahman).
🔹 The Quark–Hadron Epoch (10⁻⁶ seconds onward)
As the temperature fell to around 10¹³ Kelvin,
quarks and gluons — the most fundamental constituents of matter — condensed out of the energy field.
These quarks combined in triplets, bound by the strong force, to form protons and neutrons — the hadron era.
This was the first stable matter in the universe:
atomic nuclei in potential, still floating in a sea of high-energy radiation.
Yet the creation was turbulent — for each particle of matter, there arose one of antimatter.
When they met, they annihilated, releasing photons in immense numbers.
But a minute asymmetry — one part in a billion — allowed a tiny excess of matter to survive.
That slender residue became the foundation of every star, planet, and life form to come.
🔹 The Lepton and Photon Epochs — Light Is Born
Between one second and three minutes after the beginning,
the universe cooled enough for protons and neutrons to combine into light nuclei.
This was nucleosynthesis — the birth of hydrogen, helium, and traces of lithium.
Most of the universe became hydrogen (≈75%) and helium (≈25%),
with heavier elements yet to come much later in stars.
After about 380,000 years, when the temperature dropped to around 3,000 Kelvin,
electrons finally bonded with nuclei to form neutral atoms — a moment called recombination.
For the first time, light was free to travel through transparent space.
The universe filled with photons — the soft afterglow we now detect as the cosmic microwave background.
Water and oxygen, the essential elements of life, appeared much later,
forged in the interiors of stars by fusion and scattered across galaxies in stellar winds and supernovae.
Thus the seeds of life were born from the hearts of dying stars —
the cosmos breathing itself into consciousness.
For a detailed scientific account of this early evolution — from the first seconds to the birth of atoms and light — see my essay The First Three Minutes of the Universe.
There, the cosmological timeline is discussed in light of both physics and metaphysical insight.
Philosophical Note:
The Big Bang is the outward breath of the same consciousness that inhales creation back into silence.
Expansion and dissolution are not opposites — they are the pulse of the One.”
What science describes as differentiation, condensation, and fusion
is, in Vedantic vision, the gradual thickening of Consciousness into matter.
From the subtlest vibration (tanmātra) to the densest atom,
it is one continuum of Being — Brahman appearing as energy, form, and light.
In Vedantic vision, this is the movement from Sūkṣma (subtle) to Sthūla (gross) —
the solidification of the cosmic idea into perceptible reality.
What physics calls “matter formation,” Vedanta calls the densification of Consciousness —
the point where vibration (spanda) becomes visibility.
“From that which is full, this universe has emerged.
Though this has come forth from the full, the full remains full.”
— Isha Upanishad
The One never loses Its wholeness.
Matter does not limit Brahman; it merely reveals the infinite in finite form.
Siva–Shakti and the Quantum Mirror — Consciousness Unfolding into Form
In Vedanta and the Big Bang, the transformation from pure energy into the first atoms mirrors the Siva–Shakti principle — the eternal polarity within the One Consciousness.
Here, Siva represents Pure Awareness, the unmoving witness; Shakti is its dynamic power, the creative vibration (spandana) that manifests the universe.
Just as the unified field of physics differentiates into particles and forces, Shakti unfolds from still potential into measurable energy, and finally into tangible form.
This is not a creation from nothing, but a manifestation — the latent becoming evident, the invisible made perceivable.
“The universe arises when awareness looks at itself —
when the One becomes the mirror and the reflection at once.”
Ardhanarishvara — the sacred union of Shiva and Shakti, stillness and motion in one eternal balance.
In that sacred union of Shiva and Shakti, science finds its reflection and Vedanta its realization — the stillness and motion of the same infinite awareness.
Ardhanarishvara — the sacred union of Shiva and Shakti, stillness and motion in one eternal balance.
Philosophical Note:
Creation is not invention but revelation —
the invisible becoming visible,
the eternal expressing itself as time and form.
The Birth of Form and Conscious Order
The harmony of Vedanta and the Big Bang reveals order arising from consciousness itself.
As stars formed and worlds cooled, elements combined into intricate harmonies.
Out of apparent chaos emerged astonishing precision —
a universe fine-tuned for life, balance, and beauty.
Vedanta sees this not as chance, but as the inherent intelligence (Chaitanya) of Brahman manifesting as law and order (ṛta).
Every atom moves in rhythm with that consciousness; every galaxy dances to its silent measure.
“He who is in the sun, and he who is in the heart, are one and the same.”
— Bṛhadāraṇyaka Upaniṣad 3.7.9
Thus, the macrocosm and microcosm mirror each other.
The same awareness that shines as the sun illumines the mind within.
Philosophical Note:
Where science discovers order, Vedanta perceives awareness.
Law and consciousness are not two —
they are the structure and spirit of the same reality.
The Emergence of Life — The Universe Becomes Self-Aware
On one small planet, in one corner of this vastness,
the elements awakened into life.
From inert matter, consciousness looked back upon itself.
The universe, through the human mind, began to wonder about its own origin.
This is the reflection of Brahman within its own manifestation —
the point where the creation begins to recognize its source.
Life is not an accident; it is Consciousness returning to self-awareness through living forms.
“The Self, having entered into beings up to the tip of their nails,
looks out through their eyes and is called the person.”
— Bṛhadāraṇyaka Upaniṣad 1.4.7
Philosophical Note:
What biology calls life, Vedanta calls remembrance —
the infinite remembering itself through finite expressions.
The Inward Big Bang — Realization of the Self
As the outer universe expands, the seeker turns inward to its source.
Through viveka (discernment), dhyāna (meditation), and ātma-vichāra (self-inquiry),
the layers of Māyā dissolve.
The yogi discovers that the real singularity is within —
the still point of consciousness in which all worlds arise and subside.
“Aham Brahmāsmi — I am Brahman.”
— Bṛhadāraṇyaka Upaniṣad 1.4.10
At that instant, the distinction between observer and observed,
matter and mind, energy and awareness, disappears.
The same unity that the scientist glimpses in equations
is realized directly as the non-dual Self (Ātman = Brahman).
Philosophical Note:
The Big Bang is the outward surge of creation;
Self-realization is the inward surge of dissolution.
Both reveal the same source — stillness vibrating as existence.
Sacred Matter and the Matter of Physics
Science describes matter as energy; Vedanta sees energy as sacred. In my earlier essay, Exploring the Intersection of Ancient Wisdom and Modern Science, I examine how quantum physics, cosmology, and Upanishadic wisdom converge — reinforcing the view that science and spirituality speak the same language.
Physics teaches that matter and energy are interchangeable.
Vedanta adds: energy and consciousness are likewise inseparable.
The cosmos is not inert — it is sacred motion, the divine in dynamic form.
Every particle is a mantra, every wave a hymn.
To see the universe is to perceive Brahman expressing Itself as light, form, and life.
“Sarvam khalvidam Brahma.”
— Chāndogya Upaniṣad 3.14.1“All this is indeed Brahman.”
When one knows this, the boundary between science and spirituality dissolves.
Sacred matter and the matter of physics become one continuum of Consciousness.
Philosophical Note:
To the sage, the atom is not mere substance —
it is awareness vibrating at a measurable frequency.
To the physicist, energy is the basis of form;
to the seer, awareness is the basis of energy.
The Eternal Continuum — Beyond Creation and Dissolution in Vedanta and the Big Bang
The universe may one day cool and fade into quiet equilibrium,
but Brahman neither expands nor contracts.
It is the substratum of all becoming — the unmoved mover, the still witness of time.
“That is whole; this is whole.
From the whole, the whole arises.
Even when the whole is taken from the whole, the whole remains.”
— Isha Upaniṣad
Thus, the beginning and the end, the expansion and the silence,
are but two reflections of the same infinite reality.
Science traces outward to the cosmic horizon;
Vedanta turns inward to the luminous core —
and both dissolve in the same One without a second (Ekam eva advitīyam).

Each of these works points, in its own way, to the same indivisible truth —
that Consciousness is the field in which the universe arises, sustains, and returns to rest.
I have had the privilege of engaging with several of these works over the years — each one deepening my conviction that the ultimate reality, whether described by physics or Vedanta, is one and the same: Pure Consciousness — the irreducible foundation of all that is.
Conclusion
The riddle posed by the sages — “By knowing which, everything is known” —
finds its echo in modern cosmology.
The quest of science and the quest of self-knowledge converge:
the search for the Unified Field and the realization of Brahman are one and the same movement.
To know the Self is to know the cosmos,
for all phenomena are but Consciousness in expression.
In that knowledge, the seeker and the universe merge,
and silence remains — radiant, complete, and timeless.
Well done! Evolution unfolds through God’s will—God’s wish to express himself in many forms. Guided by the law of karma, which connects the repeating rythm of Big Bangs and Big Crunches, this process harmonises all forces. From this harmony, God shapes a perfectly ordered universe where each one of us can grow, reach its potential, and realise that were not created by God, but that we ARE God.

I am highly grateful to you for your continued support through your insights.
I wanted to include the srishti sthiti pralaya with parallel to the theory of the cyclical universe meaning an infinite number of big bangs and big crunches.
Finally it became tedious to add further reference.
Thinking of publishing another one with your inputs.
Your added insights give me further interest to think more on what you said.
I am always thankful to you.
Regards 🙏 ❤️ 🙏
Thank you for your always kind words! “From That, this has arisen; by That, it is sustained; into That, it dissolves.” Srishti, sthiti, and laya. Beautifully illustrates Vedanta’s concept of matter converting into energy and back. I am looking forward for your next piece on the true nature of Brahman!
Inspired by your words 😊🙏🪷
Sparks curiosity
Really thoughtful read — you’ve framed the question of “that by which everything is known” in a rich way, weaving together Vedanta and modern cosmology so elegantly. The reflections on consciousness and the cosmos invite a pause, and remind me how the inner and outer worlds mirror each other. 🙏
Thank you so much Sir for your kind comments.
I am encouraged by your words.
Now -a-days hardly people stop in these reads.
I find this subject is primarily very important for people to understand the real nature of the Self.
Best regards to you Atul ji.
