The Vedic Consciousness and Distributed Systems: One in Many, Many in One
A fresh perspective on how the ancient concept of Consciousness illuminates the interconnectedness of modern software -
The Vedas have existed since before many things we consider ancient. They answer fundamental questions about consciousness, reality, and the nature of existence and much more beyond our capacity to imagine and perhaps, analyze independently. The Yajurveda, one of the four vedas is composed of six Upanishads (explanatory texts).
Among these texts, the Brihadaranyaka Upanishad stands as one of the oldest and most profound. It opens with a remarkable declaration about the nature of wholeness that, surprisingly, offers deep insights into modern distributed systems architecture:
॥ॐ पूर्णमदः पूर्णमिदं पूर्णात्पूर्णमुदच्यते पूर्णस्य पूर्णमादाय पूर्णमेवावशिष्यते ॐ शान्तिः शान्तिः शान्तिः ॥
(Om Poornamadah Poornamidam Poornaat Purnamudachyate Purnasya Purnamaadaaya Poornamevaavashishyate) (Om Shantih Shantih Shantih)
"That is complete, this is complete. From the complete comes the complete. Taking the complete from the complete, The complete remains." “Om Peace, Peace, Peace.”This verse, known as the Purnam mantra, commonly used in meditative teachings and practices. It explores how wholeness manifests in different forms while maintaining its essential nature. The Upanishads use this concept to explain the relationship between universal consciousness (Paramatma) and individual consciousness (Jivatma).
Remarkably, this same framework illuminates how modern distributed applications maintain their core functionality across multiple instances.
The Complete Application (Poornamadah)
In distributed systems, the application itself represents Poornamadah ("that completeness"), the Paramatma of our system. This isn't just about code or functionality – it encompasses the complete essence, the blueprint, of what the application is and does. Like universal consciousness in Upanishadic thought, this essence contains everything needed for the application's existence and operation.
The application's core functionality manifests through its codebase, business logic, data models, and behavioral definitions. It includes every possible state transition, every business rule, every validation check, and every processing capability. This essence remains unchanged regardless of deployment strategy or scaling decisions. Just as Paramatma remains constant while manifesting in countless forms, the application's essential nature persists unchanged across all its instances.
The Independent Instance (Poornamidam)
When we deploy our application, each running instance becomes Poornamidam ("this completeness"), a Jivatma carrying the complete application essence. Every container, every deployment contains not just a part or subset of the application, but its complete capability – a fully functional unit. This mirrors the Upanishadic understanding that each individual consciousness contains the complete essence of universal consciousness.
A running instance maintains its independence while remaining fundamentally connected to the application's core logic. It processes requests, maintains state, and executes business logic autonomously. This independence doesn't imply isolation; each instance represents a complete manifestation of the application’s design, just as each Jivatma contains the complete essence of Paramatma. However, these instances must also interact and share state to function as a cohesive system. This coordination between independent, yet interconnected units is a key characteristic of distributed systems.
From Complete to Complete (Poornaat Purnamudachyate)
The process of creating new instances embodies Poornaat Purnamudachyate – "from the complete comes the complete." Each deployment, each container instantiation, represents a whole arising from a whole. When we spawn a new instance, we're not creating a partial or limited version of our application. Instead, we're manifesting another complete expression of its blueprint.
This principle underpins modern deployment practices. When a container platform like Kubernetes creates new pods, each one receives a replica of the application's core logic and dependencies, enabling it to operate independently. Autoscaling leverages this principle to seamlessly expand capacity: each new pod embodies the full application functionality, ensuring consistent behavior regardless of scale. This replication doesn’t dilute the application’s essential functionality; rather, it multiplies its availability while preserving its integrity.
Completeness Remains (Purnasya Purnamaadaaya Poornamevaavashishyate)
The final line of the shloka captures a profound truth about distributed systems: Purnasya Purnamaadaaya Poornamevaavashishyate – "taking the complete from the complete, the complete remains." This perfectly describes how distributed applications maintain their integrity through scaling, updates, and failures.
When we scale up our application by adding instances, the original essence remains unchanged. When instances fail and are replaced, the application's core functionality persists. Even as we deploy across multiple regions or clouds, the defining logic of the application remains constant. Each instance, while complete in itself, doesn't diminish or divide the application's essence – just as the light of a candle can light many others without diminishing its own flame. This principle is crucial for maintaining consistency and availability in the face of failures or fluctuating demand.
Practical Applications
The Upanishadic framework reveals key patterns in modern distributed systems:
Immutable Design
Container images capture our application's pure essence. Each container manifests identical functionality wherever it runs, embodying the principle of "from the complete comes the complete." A container built in development reproduces the same behavior in production, acting as a complete unit that carries forward the application's core nature.
Connected State
While containers represent our application's logic, state forms a complementary aspect of completeness. Through distributed data systems, each instance connects to the same underlying state - mirroring how individual consciousness links to universal consciousness. The state remains whole regardless of how many instances access it.
Closing Thoughts
A key aspect of this completeness is the intricate connectedness it encompasses.
Ancient wisdom offering fresh perspectives on modern technical challenges is nothing new. A certain J. Robert Oppenheimer comes to mind when thinking on the matter…
In this case though, the Purnam mantra illuminates more than architectural patterns - it provides a framework for understanding how systems maintain wholeness as they scale. The relationship between individual components and collective harmony, captured so elegantly in Upanishadic thought, can continue to guide how we imagine resilient distributed systems.
