The gist of Hinduism - Soul is immortal - doesn't it remind us about the conservation of Mass and Energy of modern physics - it's time for Bharat to embrace Sanskrit....

The idea that the soul is immortal in Hinduism can be intriguingly compared with modern scientific principles like the conservation of mass and energy. While the domains are different — metaphysical vs physical — the philosophical resonance between them is worth exploring.

Hindu View: Soul Is Eternal and Imperishable

In Bhagavad Gita (Chapter 2, Verse 20):

"na jāyate mriyate vā kadācin..."

"The soul is never born and never dies; it is eternal, ever-existing, and primeval. It is not slain when the body is slain."

Key concepts:

• Ātman (आत्मन्) = The individual soul

• Immortal: Not subject to birth or death

• Transcendental: Beyond the physical body and matter

• Cycles of birth and rebirth (Saṃsāra), but the ātman itself remains unchanged

Modern Science: Conservation Laws

1. Conservation of Mass-Energy (Einstein’s Equivalence)

$$E = mc^2$$

• Matter and energy are interchangeable

• In any closed system, mass-energy is never created or destroyed — it only transforms

• After death, the body's mass returns to the environment (soil, gases, etc.), and its energy dissipates as heat, motion, etc.

2. First Law of Thermodynamics

Energy can neither be created nor destroyed, only transformed.

3. ∇⋅U=0, for non-compressible fluid in CFD

Philosophical Similarity

Hinduism (Ātman)	Modern Physics (Mass/Energy)
Soul is never created or destroyed	Energy/mass is never created or destroyed
Soul changes bodies (rebirth)	Energy changes forms (heat, light, motion)
Body is temporary; soul persists	Objects decay, but mass-energy persists
Soul is subtle, invisible	Energy is abstract, invisible but measurable

Spiritual vs Scientific Lens

Aspect	Hinduism (Metaphysical)	Science (Physical)
Subject	Soul (Ātman)	Mass, Energy
Measurability	No (based on inner experience)	Yes (quantifiable)
Immortality	Eternal existence beyond time	Conservation across physical processes
Framework	Vedanta, Yoga, Gita	Physics, Thermodynamics, Relativity

Deeper Interpretive Parallel

• Just as energy transforms without loss, the soul transmigrates without ending.

• Death is not destruction — it is transition, in both models:

  • In physics: from matter to heat/light/sound

  • In spirituality: from one body to another (rebirth)

Final Reflection

While Hinduism’s soul is not material, and science does not comment on the metaphysical, both present a worldview in which essence is preserved and only appearances change.

So:

"Nothing truly ends — it only transforms." 

This principle, whether found in the Gita or the laws of physics, continues to inspire both spiritual seekers and scientific minds alike.
