In this blog, we will continue our exploration of the nature of reality by investigating the striking parallels between quantum physics and Eastern spiritual traditions, particularly Buddhism. Over the last century, science has begun to uncover truths about reality that echo ancient teachings, most notably the concept of "emptiness" as the ground of all existence.
Emptiness: Nagarjuna’s Mulamadhyamaka Interpretation
Nagarjuna, a foundational thinker in Mahayana Buddhism, explored the concept of emptiness (shunyata) in his seminal text, the Mulamadhyamaka-karika. For Nagarjuna, emptiness is not a void or nihilism but the absence of intrinsic, independent existence in all phenomena. It underscores the idea of pratītyasamutpāda (dependent origination): everything arises due to causes and conditions, existing relationally rather than autonomously.
This interdependence implies that things lack an inherent "self-nature," making their apparent solidity and separateness illusory. Nagarjuna's insight challenges binary oppositions—existence vs. non-existence—and redefines reality as dynamic and interconnected, rooted in relationality rather than absolutes.
An apt analogy is a blank sheet of paper. A blank sheet of paper, inherently devoid of meaning, symbolizes emptiness. While the paper itself conveys nothing, it serves as the potential foundation for infinite expressions—stories, art, or knowledge. Similarly, emptiness isn’t a void but the fertile ground from which phenomena arise and dissolve.
Nagarjuna’s insights resonate with modern perspectives, such as quantum physics, where matter emerges from a quantum field, where particles exist as probabilities, and their state is relationally defined, often only actualized upon observation. Together, they reveal a profound unity underlying the apparent diversity of the universe.
Reality and Emptiness in Nagarjuna’s View - Dependent Origination
Pratītyasamutpāda, often translated as "dependent origination" or "dependent arising," is a central doctrine in Buddhist philosophy. It explains how all phenomena arise in dependence on other factors, emphasizing that nothing exists independently or intrinsically. This insight underpins the understanding of shunyata (emptiness).
Key Features of Pratītyasamutpāda
Interdependence of Phenomena: All things arise because of specific causes and conditions. For instance, a tree exists because of seeds, soil, sunlight, water, and time. Without these interdependent factors, the tree cannot exist.
No Intrinsic Nature (Svabhava): Since phenomena arise through conditions, they lack an inherent, unchanging essence. This absence of intrinsic existence aligns with the concept of emptiness.
Twelve Links of Dependent Origination: The doctrine is often illustrated through the cycle of existence, represented by the twelve links (nidanas), which describe how ignorance and craving perpetuate samsara (cyclic existence). The links include:
Ignorance (avidya): Lack of understanding of reality and the Four Noble Truths.
Volitional Actions (samskara): Karmic formations driven by ignorance.
Consciousness (vijnana): Awareness conditioned by previous karma.
Name-and-Form (nama-rupa): Mental and physical components of existence.
Six Sense Bases (shadayatana): Eyes, ears, nose, tongue, body, and mind.
Contact (sparsha): Interaction between sense organs and objects.
Feeling (vedana): Sensory experience as pleasant, unpleasant, or neutral.
Craving (trishna): Desire arising from feelings.
Clinging (upadana): Attachment to desires.
Becoming (bhava): The process of existence and karmic potential for rebirth.
Birth (jati): Entry into a new life.
Aging and Death (jara-marana): The inevitable decline and dissolution of existence.
Practical Implications
Understanding pratītyasamutpāda helps dismantle attachment and aversion by revealing that nothing exists in isolation.
It promotes a worldview of interconnectedness, fostering compassion, as all beings are intertwined in the same web of conditions.
It provides a pathway to liberation by breaking the chain of conditioned existence through insight and mindfulness.
In essence, pratītyasamutpāda reflects a universe that is fluid, interconnected, and free from inherent boundaries, mirroring the dynamic potentiality seen in both Nagarjuna's philosophy and modern scientific concepts like the quantum field.

Emptiness as Middle Path
Nagarjuna’s critique of intrinsic nature is a cornerstone of his philosophy, particularly within the framework of Madhyamaka (the Middle Way). His argument is a direct challenge to essentialist views that assert that things have an inherent, unchanging essence or nature.
The Problem of Intrinsic Existence: Nagarjuna posits that if phenomena (whether material objects or mental events) had intrinsic or inherent nature (svabhava), they would be static, independent, and self-sufficient. In other words, they would not change, evolve, or interact with other phenomena. An inherent essence would imply that phenomena are independent of causes and conditions, existing in isolation, unaffected by time, context, or relationships. However, we observe that all things are in constant flux and are deeply interdependent.
Take, for example, a seed. A seed contains no essence of the tree it will eventually grow into, but it is dependent on soil, water, and light to manifest into a tree. If the seed were intrinsically a tree, it should already be a tree by itself, regardless of conditions.
Dependence on Causes and Conditions: Nagarjuna’s theory of dependent origination (pratītyasamutpāda) asserts that all phenomena arise in dependence upon causes and conditions. No phenomenon exists by itself, and its identity or nature emerges through its relationships with other things. For instance, a cup is not a cup in isolation; it is a cup because of the shape, material, purpose, and the context in which it is recognized as a cup.
If phenomena had intrinsic existence, there would be no room for this interdependent arising. Things would be self-contained and unchanging, rather than continuously arising and passing away in accordance with a web of conditions. Therefore, the very concept of intrinsic nature collapses in the face of the observable flux and interconnectedness of the world.
The Dismantling of Identity: One of the most profound implications of Nagarjuna’s view is its impact on identity, both of objects and of the self. If things don’t have an intrinsic nature, then they are not what we conventionally think they are. Their identity is relational, contingent upon context and perception. This applies not just to physical objects, but also to the notion of the self.
Nagarjuna’s critique suggests that our understanding of self is also an illusion rooted in fixed ideas. If the self had an intrinsic nature, it would be a permanent, unchanging entity. However, the self is also a phenomenon that depends on causes and conditions, constantly changing and evolving. The idea of a permanent, independent "I" becomes untenable when we recognize the interdependent and impermanent nature of all phenomena.
The Consequences for Perception and Reality: By rejecting the concept of intrinsic existence, Nagarjuna challenges our perceptions of reality. We are inclined to categorize things as having fixed natures (a cup is a cup, a tree is a tree, and so on), but Nagarjuna’s reasoning forces us to see these as conventional designations rather than absolute truths. This radical shift in perspective destabilizes fixed, rigid worldviews, calling for a more flexible, interconnected understanding of existence.
At a deeper level, Nagarjuna is suggesting that the very fabric of reality is empty of inherent, self-contained essence. Instead, it is empty of any such fixed nature. This śūnyatā (emptiness) is not a void or nothingness but the absence of inherent, independent existence.
Implications for Liberation: One important aspect of Nagarjuna’s teachings is that realizing emptiness is the path to liberation. When one understands that all phenomena (including the self) are empty of inherent existence, one can see through the illusion of permanent, separate entities and grasp the truth of their interdependence. This leads to the cessation of clinging and attachment, which are seen as the causes of suffering.
In this sense, the "field of potential" is not only a metaphysical concept but also a spiritual insight. Understanding emptiness helps to free the mind from the grasp of fixed concepts and gives rise to wisdom that sees reality as interconnected, interdependent, and ever-changing. The realization of emptiness is transformative because it allows one to let go of rigid concepts of self and other, offering a direct experience of the fluid, interconnected nature of all phenomena.

Emptiness and the Quantum Field
Buddhism often describes this emptiness as the infinite potentiality from which all phenomena arise and eventually return. The universe is in a state of constant flux, where all things are empty of any permanent, independent identity. This emptiness is dynamic and fertile, capable of giving rise to all the forms and experiences we encounter, but these phenomena are ultimately transient and interdependent.
In modern physics, particularly in quantum field theory (QFT), the quantum field is a fundamental concept. It suggests that beneath the apparent material world, there exists a unified field that permeates all of space. The quantum field is the foundation of all particles and forces in the universe. Unlike classical physics, where particles are considered discrete, quantum field theory asserts that particles are excitations or fluctuations in this underlying field.
This quantum field is considered primordial, non-local, and timeless. It is beyond our ordinary perceptions of time and space. When we observe phenomena such as electrons or photons, what we are actually seeing are localized, discrete expressions of this field. These particles are not independent entities with fixed existence but rather manifestations of the quantum field, emerging and dissipating according to the laws of quantum mechanics.
Influences on the “Deeper Field of Potential” (Emptiness)
In Nagarjuna’s framework, emptiness (śūnyatā) is not an entity influenced by external factors; rather, it is the inherent lack of independent, fixed existence in all phenomena. What influences the arising of phenomena from this "field of potential" is the interconnected web of causes and conditions.
For human beings, this means that karma (intentional actions) and mental patterns heavily influence what arises in thought and behaviour. Just as ripples in a pond arise from a combination of wind, pebbles, and currents, human experiences arise based on prior actions, current conditions, and mental tendencies. The potential for various thoughts and actions is always present, but what manifests depends on:
Past actions (karma): Accumulated intentional actions create tendencies that influence future thoughts and actions.
Current circumstances: Environmental factors, relationships, and immediate stimuli shape the manifestation of potential.
Intention and mindfulness: A conscious intention can guide which potentials are activated, much like steering the direction of a ship.
Manifestation of Potential
When a thought or action manifests, it emerges from the dynamic interplay of conditions. In Buddhism, this transition is fluid, with no fixed entity causing it. Instead, it is like a wave cresting in the ocean—its shape, size, and timing are determined by the interaction of countless forces.
A thought arises when the mind encounters a stimulus (internal or external) that aligns with past conditioning and current focus.
An action follows when this thought triggers volition, which sets the mental and physical processes into motion.
This mirrors the quantum idea of a superposition of potentials, where the observation or interaction determines the specific outcome. In quantum mechanics, a particle such as an electron exists in a state of superposition—a wave of infinite potentialities—until it is observed or interacts with something else. At the moment of observation, the wave "collapses" into a definite state, becoming a particle with specific properties (e.g., position or momentum).
Wave-Particle Duality and Emptiness
One of the central ideas in quantum physics is wave-particle duality, which reveals that particles such as electrons or photons can behave both as particles and as waves, depending on how they are observed. This dual nature suggests that at the quantum level, reality is not fixed but rather fluid, emerging in different forms depending on the context of observation. Similarly, in Buddhism, the concept of emptiness suggests that phenomena, including the self, are not fixed or self-contained but arise from a deeper field of potential, manifesting in various forms that are constantly in flux.
Now, to tie this to a common experience: many people feel that they are interacting with solid, real objects, such as when sitting in a chair. However, quantum physicists explain that you are not actually touching the chair in the way we conventionally think. What you are experiencing is actually a repulsive force between the atoms in your body and those in the chair. This force, similar to the interaction between like poles of magnets, prevents the atoms from coming into direct contact. Therefore, what feels like solid matter is, in reality, a field of energy at the atomic level. This force creates the illusion of solidity, just as the dynamic waves of the ocean create the illusion of discrete, separate water particles.
This sensation of "solidness" is, in fact, illusory—what we are really experiencing is the energy exchange, not matter as a fixed entity. The repulsive force that we feel is analogous to the experience of emptiness—it is an underlying process that gives rise to the appearance of solid forms, just as the quantum field gives rise to the appearance of particles and matter. In both cases, we perceive what seems to be solid and real, but deeper down, these phenomena are actually interdependent and not fixed in their essence.
This brings us back to the quantum field, which is outside of our direct perception but remains as the pure potentiality for matter to arise. All the particles that make up atoms—the very building blocks of what we consider physical reality—arise from this field. However, they are not separate from the field; they are expressions of it, much like how waves are expressions of the ocean. The quantum field itself is spread across all of space and time, and it is the very foundation from which all matter, all atoms, the universe itself, and even our very selves arise.
At the most fundamental level, matter and energy are simply different manifestations of the same underlying reality. Whether it's a rock, a tree, or the sensation of touch, these experiences arise from this quantum field, just as Buddhist teachings suggest that all phenomena are expressions of the empty nature of reality. Ultimately, just as the waves fall back into the ocean, all matter and energy fall back into the quantum field. Everything arises from and dissolves back into this unified ground, revealing the interconnectedness of all things.
This resonance between quantum field theory and Buddhist emptiness (and Advaita's Purnam) suggests that our perceptions of solidity and permanence are illusory. Both perspectives invite us to recognize the fluidity and interdependence of all phenomena, pointing to a deeper, unified reality beneath the surface of appearances.
The Role of Consciousness and Intention
In both systems, consciousness plays a key role in shaping manifestation:
In quantum mechanics, some interpretations (e.g., the observer effect) suggest that consciousness impacts the outcome of potential states.
In Buddhism, mindfulness and volition guide the activation of latent tendencies, allowing a person to influence which potentials become manifest.
This implies that awareness is a key factor in transitioning potential to manifestation. For instance:
Unconscious habits: Potentials manifest based on ingrained tendencies, akin to particles arising through random interactions.
Conscious intention: With mindfulness, one can steer thoughts and actions toward constructive outcomes, much like shaping the conditions for specific phenomena to arise.
Bridging the Two: Dynamic Interplay of Potential and Manifestation
From Potential to Action
In Buddhism: A thought arises when karmic imprints, current conditions, and intention align. When volition is added, this thought translates into speech or action.
In Physics: A wave collapses into a particle when a measurement or interaction reduces its superposition to a definite state.
Interdependence
Both systems emphasize that the manifested form is not independent:
A manifested thought or action arises due to interdependent causes.
A particle’s existence depends on the quantum field and its interactions.
Illusory Solidity
In both cases, the "solid" or "fixed" nature of the manifested state is illusory:
A thought, once manifested, is fleeting and leads to other dependent phenomena.
A particle, though appearing localized, is still interconnected with the field and retains wave-like properties.
Quantum Entanglement: A Scientific Perspective
Quantum entanglement occurs when two or more particles become linked such that the state of one particle is instantaneously correlated with the state of another, no matter the distance separating them. This phenomenon was famously demonstrated in the EPR paradox and subsequent experiments verifying Bell’s Theorem, which proved that the correlations predicted by entanglement cannot be explained by classical physics or local hidden variables, as declared by Einstein.
Key features of entanglement:
Non-locality: Changes in one particle are reflected in its entangled partner instantaneously, even across vast distances, suggesting a connection beyond the limits of space and time.
Unity despite separation: Although particles appear distinct, their behaviors are inseparably linked, pointing to an underlying unity.
Relational existence: The properties of an entangled particle (e.g., spin) don’t exist independently but only in relation to the other particle.

The Parallels: Entanglement and Interdependence
Non-local Unity
Quantum Physics: Entangled particles demonstrate that separateness is illusory. Despite spatial separation, they behave as a single, unified system.
Buddhism: Interdependence reveals that no phenomenon is truly separate. The boundaries we perceive (e.g., between self and other) are constructs; in reality, everything is part of an interconnected whole.
Relational Identity
Quantum Physics: The properties of an entangled particle (e.g., spin) do not exist independently but are defined in relation to its partner.
Buddhism: The identity of all phenomena is relational, arising from their interconnections. For example, a tree exists because of soil, water, sunlight, and countless other factors—it has no independent essence.
Beyond Space and Time
Quantum Physics: The instantaneous correlation between entangled particles challenges the classical idea of spacetime as a limiting framework.
Buddhism: Interdependence transcends conventional notions of time and space. For instance, actions performed in the past (karma) influence the present and future, demonstrating a continuity that is not bound by linear time.
Illusion of Separateness
Quantum Physics: Entanglement reveals that what appears as distinct entities (particles) are fundamentally interconnected.
Buddhism: The notion of a separate self is an illusion. The self is a composite of interdependent processes (skandhas), not an independent entity.
Conclusion: A Unified Perspective
At the heart of both Nagarjuna's Madhyamaka philosophy and quantum physics lies a transformative insight into the nature of reality: what we perceive as solid, fixed, and independent is, in fact, dynamic, interdependent, and void of inherent essence. This profound parallel invites us to reconsider the foundational assumptions that shape our understanding of existence, whether through the lens of metaphysics or modern science.
Nagarjuna's teachings on dependent origination and emptiness reveal a profound view of interconnection and the absence of inherent essence, resonating with the principles of quantum physics. Both frameworks emphasize reality as a dynamic web of relationships, where phenomena arise from interdependence rather than fixed identities. The concept of emptiness aligns with the quantum field, representing potential and fluidity rather than voidness. This synthesis invites a deeper understanding of unity beneath apparent separations, whether in Buddhist philosophy or the fabric of the quantum universe.
The convergence of Nagarjuna’s Madhyamaka and quantum physics offers a radical shift in how we view reality:
Relational Reality: Both frameworks reveal that nothing exists independently—identity arises only in relation to other factors.
Dynamic Potential: Reality is a process, not a static structure. Manifestations emerge from a field of potentiality, shaped by conditions and interactions.
Illusory Solidity: The perceived "solidity" of objects and the self is an illusion arising from relational forces, whether the repulsion of atoms or mental constructs.
Unity in Diversity: Beneath the appearance of multiplicity lies an interconnected unity, whether expressed through quantum entanglement or the Buddhist principle of oneness.
By bridging these two profound insights, we are invited to let go of rigid notions of self and world, embracing a reality that is interconnected, dynamic, and open-ended. This understanding not only transforms our intellectual grasp of existence but also offers a path to greater compassion, wisdom, and harmony with the universe. In both science and spirituality, the journey leads to the same realization: The boundaries we perceive are mere illusions, and beneath them lies an infinite, unified potential.
