One might call it “Heart Sutra Science”

1. Introduction

Science and spirituality often seem worlds apart: the former devoted to empirical and mathematical rigor, the latter to contemplative or mystical insights. Yet there are striking resonances between these realms. Noether’s theorem—a foundational principle in physics—asserts that whenever a system displays a continuous symmetry, there is a corresponding conservation law (e.g., time-invariance implies conservation of energy). Meanwhile, Buddhist philosophy, particularly as expressed in the Heart Sutra and Nagarjuna’s writings, stresses the interdependence and emptiness (śūnyatā) of phenomena, pointing out how things exist relationally rather than as fixed substances.

This essay explores the phenomenological, first-person dimension of these ideas. By analyzing a single moment of lived experience—such as a breath in meditation—we can see how symmetrical relations and conservation-like principles appear in our own conscious processes. Nagarjuna’s Catuskoti (the “four-cornered” logic) will help us see how claims about existence and non-existence, permanence and impermanence, can be reframed in light of emptiness and dependent origination. The end goal is to highlight an unexpected harmony between the physical insight of symmetries and conservation (Noether’s theorem) and Buddhism’s proclamation that all dharmas (phenomena) are empty of intrinsic essence yet remain functionally effective through interdependence.


2. Noether’s Theorem and the Symmetry of Emptiness

2.1 A Brief Overview of Noether’s Theorem

Emmy Noether’s theorem (1918) is a cornerstone of theoretical physics. In simplified terms, it states:

Whenever a system’s action (governing equations) remains invariant under a continuous symmetry, a corresponding conservation law arises.

  • Time invariance Conservation of energy
  • Spatial translational invariance Conservation of momentum
  • Rotational invariance Conservation of angular momentum, etc.

In each case, the “invariance” refers to the idea that the system’s fundamental equations or action do not change when transformed according to a certain symmetry (e.g., shifting the time coordinate or rotating the reference frame).

2.2 Symmetry in a Buddhist Context

From a Buddhist standpoint—particularly the Heart Sutra—all phenomena (dharmas) are:

  1. Empty of own-being: They have no permanent or unchanging essence (no svabhāva).
  2. Arising dependently (pratītyasamutpāda): Their existence is contingent upon relationships with other phenomena.

When we overlay these ideas onto Noether’s theorem, we might reinterpret “symmetry” as a form of relational balanceamong empty phenomena. The “conservation laws” are not about locked-in substances persisting through time. Instead, the stability or “conservation” we observe emerges from invariant relational structures—networks of dependent origination that remain functionally consistent under transformations (e.g., time shifts or spatial translations).

In other words, emptiness does not negate phenomena. It reveals that their “conserved” properties (like energy or momentum) exist not as intrinsic possessions but as relational invariants. This parallels the Heart Sutra’s teaching that while all dharmas are empty, they remain “form” in a conventional sense, co-arising in a web of interdependence.


3. The Lived Moment: Phenomenological Analysis

3.1 Observing the Breath Through the Five Skandhas

To ground these ideas in direct experience, consider a simple moment of sitting meditation where you focus on the breath. From a Buddhist taxonomical lens, this experience can be broken into the five skandhas (aggregates):

  1. Form (rūpa): The physical sensation of the breath—air passing through nostrils, the expansion/contraction of the abdomen.
  2. Sensation (vedanā): The feeling tone—pleasant, unpleasant, or neutral—as the breath moves.
  3. Perception (saṃjñā): Recognition: “This is breathing,” the labeling of inhalation vs. exhalation, etc.
  4. Mental Formations (saṃskāra): Volitional states (the intention to remain focused) and other mental factors (judgments, subtle urges to shift posture, etc.).
  5. Consciousness (vijñāna): The bare awareness that illuminates the entire process, registering each aspect as an experience.

By carefully attending to these five components, you notice that nothing remains static:

  • The Form of the breath changes moment by moment.
  • Sensation shifts—sometimes more pleasant, sometimes neutral.
  • Perceptions can become sharper or dull as attention waxes and wanes.
  • Mental formations arise and fade (e.g., the impulse to refocus if mind-wandering occurs).
  • Consciousness itself appears continuous, yet on closer inspection, it too exhibits a dynamic flux—moments of clarity, subtle lapses, re-dawning of attention.

3.2 Emptiness in the Meditative Moment

Applying the Heart Sutra’s proclamation—“Form is emptiness, emptiness is form”—in meditation reveals that each skandha arises interdependently:

  • The breath (form) relies on bodily processes, atmospheric pressure, and mental awareness to be recognized.
  • The sensation (vedanā) depends on neural activity and contextual interpretation (e.g., how your posture feels today).
  • Perception is shaped by prior experiences (“I know what breathing feels like”), subtle expectations, and language.
  • The mental formations guiding you to keep focus are not absolute commands from a separate, unchanging self but arise conditionally based on your motivation, mindfulness training, and mental habits.
  • Consciousness is not an isolated “observer” but an ongoing interplay shaped by momentary conditions and the other skandhas.

In seeing how none of these aspects hold a permanent essence, the “empty” nature of each skandha becomes experientially tangible, even as they function and interact seamlessly.


4. Nagarjuna’s Catuskoti and the Symmetry of Dharmas

4.1 The Four Corners of Inquiry

Nagarjuna’s Catuskoti lays out four possible stances regarding a proposition (e.g., “the breath exists”):

  1. It exists
  2. It does not exist
  3. It both exists and does not exist
  4. It neither exists nor does not exist

In a purely logical analysis (the so-called “tetralemma”), these can seem contradictory or puzzling. But for Nagarjuna, the point is to show how conceptual extremes fail to capture the subtlety of dependent origination.

4.2 Applying the Catuskoti to the Meditative Breath

  • It exists: Conventionally, the breath is a real phenomenon—observable, measurable, vital.
  • It does not exist: Ultimately, the breath has no fixed essence (it is empty); it is a fleeting interplay of countless conditions (body, mind, air, etc.).
  • It both exists and does not exist: Phenomena operate conventionally while being empty ultimately; these two truths are not mutually exclusive.
  • It neither exists nor does not exist: We see that trying to pin the breath as “absolutely real” or “absolutely nonexistent” goes beyond conceptual fixations, echoing Nagarjuna’s “middle way” (madhyamaka).

4.3 Mirroring Noether’s Invariance in Dharmas

When you see that the breath “both is and is not”—that it arises as an interdependent phenomenon—this reveals a kind of invariance. It consistently behaves in relationship to the body, environment, and consciousness, but that consistency arises relationally rather than from a permanent “something.” This parallels how Noether’s theorem sees conservation laws: they are not rooted in an immutable substance but in invariance principles—the structural “emptiness” or relational “DNA” of the system.


5. Empty Dharmas, Conservation, and Insight

5.1 Conservation as Dependent Origination

In physics, “conservation laws” state that certain quantities (energy, momentum, etc.) remain constant over time. If we interpret these laws through a Buddhist lens, they become statements about how a system’s relational structure remains stable under transformations. They do not assert a “thing” that eternally exists but reflect how processes continue in an unbroken chain, dependent on symmetrical conditions.

5.2 Noether’s Theorem and Pratītyasamutpāda

Noether’s theorem can thus be read as a formal corollary of pratītyasamutpāda (dependent origination) in the sense that every “conserved quantity” points to an underlying symmetry in how phenomena relate—i.e., a stable pattern that emerges from cyclical or self-consistent interactions. This pattern is empty of a separate essence, yet it is observableand functionally valid.


6. Proving Noether’s Theorem Within Nagarjuna’s Catuskoti?

6.1 A Non-Mathematical “Proof”

Strictly speaking, Noether’s theorem in physics is a mathematical statement requiring Lagrangians, variations of action, and group theory. Nagarjuna’s Catuskoti is a philosophical tool for undermining conceptual extremes and revealing emptiness. How, then, might we talk of “proving” Noether’s theorem in the context of Catuskoti?

  1. Revelatory Parallel: Nagarjuna dismantles the idea that phenomena possess or lack existence absolutely. Noether’s theorem dismantles the idea that conserved quantities exist as brute facts; instead, they exist only in the presence of invariance (a relational structure).
  2. Common Ground in Emptiness and Symmetry: In both frameworks, “essences” dissolve. Noether’s theorem localizes the cause of “conservation” in a system’s symmetrical structure. Nagarjuna localizes the “essence” of phenomena in the interdependence of conditions.
  3. Four Corners, Four Perspectives on Symmetry: If we try to claim a symmetry is absolutely real, or absolutely unreal, or both, or neither, we discover (like the breath) that symmetry is a relational phenomenon: it depends on the system’s formulation and the observer’s transformations. This parallels the Catuskoti’s demonstration that single-position claims about ultimate existence fall short.

Hence, “proving” Noether’s theorem within the Catuskoti amounts to showing the conceptual synergy: the emptiness of phenomena allows symmetrical invariances to become the “locus” for what we call “conservation.” The theorem and the Catuskoti both converge in illustrating that no static essence is required for stability to occur.


7. Conclusion

By expanding a simple moment of phenomenological analysis—the breath in sitting meditation—through the lens of Buddhist taxonomies (five skandhas, emptiness) and Nagarjuna’s Catuskoti, we see a striking parallel to Noether’s theorem’s principle of symmetry and conservation:

  • All dharmas are empty: No phenomenon has an independent, unchanging substance.
  • Symmetries produce conservation: Stability or consistency (whether of breath or energy) arises from relational invariance, not from an absolute entity.
  • The Catuskoti: Shows that existence claims can only be provisionally asserted (conventional truth), but ultimately, phenomena defy reification (ultimate truth).

In the meditative moment, we notice the breath’s dynamic nature. It “exists” in a conventional sense, “does not exist” in an ultimate sense, “both exists and doesn’t” as a fusion of form and emptiness, and “neither exists nor doesn’t” when we relinquish all conceptual extremes. These four vantage points mirror how Noether’s theorem demonstrates that conservation laws emerge not from any one ultimate substance but from the self-consistent relational structure of a system.

In short, phenomenological experience and Buddhist emptiness do not undermine the empirical findings of modern physics—rather, they can illuminate why these findings might take the form they do, offering an integrative vision. Both spiritual wisdom and scientific theory uncover invariant patterns in experience and reality, attesting to a shared commitment: that there is no fixed “essence” behind phenomena, yet patterns of stability naturally arise due to the interwoven tapestry of relations.
