Background

Harikathamrutasara Part 8, Bhojana Sandhi. The Hidden Science Treasure is described in MantralayaCompassion of Sri Rayaru is described in Mantralaya (2101).

Meaning

In Mantralaya (2010), we explored the Bhojana Rasa Vibhaga Sandhi from a spiritual perspective. Now, let us re-examine the same profound composition through the lens of modern science. To do justice to the depth and brilliance of the Harikathamrutasara, especially the Bhojana Rasa Vibhaga Sandhi, this exploration will be presented in multiple parts. The aim is to present Sri Jagannatha Dasaru's insights in a way that aligns with contemporary scientific understanding, enabling the present generation to appreciate the remarkable depth of Vedic knowledge embedded in this timeless work.

One of the most profound observations made by Sri Jagannatha Dasaru in the Bhojana Rasa Vibhaga Sandhi is deceptively simple, the individual consciously performs none of the essential functions that sustain life. What appears at first to be a devotional reflection on eating gradually unfolds into a profound meditation on the nature of existence itself. The Sandhi invites the devotee to recognize that the body is maintained not through personal effort or independent power, but through an uninterrupted process of divine governance.

Centuries before the emergence of modern physiology, molecular biology, and neuroscience, Sri Jagannatha Dasaru directed attention to a truth that contemporary science increasingly reveals with remarkable clarity: life depends upon an incomprehensibly intricate network of coordinated processes operating entirely beyond conscious awareness.

Let us now examine this profound insight of Sri Jagannatha Dasaru through the lens of modern science.

Modern biology has transformed our understanding of the human body. Rather than viewing it as a collection of independent organs performing isolated tasks, science now understands it as a highly integrated, dynamic and self-regulating system composed of trillions of interacting cells. Every organ, tissue, cell and molecule participates in an immense network of communication through electrical impulses, chemical messengers, mechanical signals and genetic regulation. At every moment, countless physiological processes occur simultaneously with extraordinary precision, maintaining the internal conditions necessary for life despite continuous changes in the external environment. This remarkable stability, known as homeostasis, is one of the foundational principles of modern physiology.

Homeostasis involves far more than maintaining body temperature or blood pressure. Every second, the body continuously monitors and regulates hundreds of physiological variables within remarkably narrow limits. Body temperature remains close to 37°C despite environmental fluctuations. Blood glucose is tightly controlled to supply the brain while preventing tissue damage. Blood pH is maintained between approximately 7.35 and 7.45, as even slight deviations can impair enzyme function and threaten survival. Oxygen and carbon dioxide levels, electrolyte balance, blood volume, blood pressure, hormones, nutrients and countless signalling molecules are all regulated through interconnected feedback systems. None of these processes require conscious attention. Indeed, if they depended upon deliberate human effort, survival would be impossible.

The autonomic nervous system illustrates this principle with remarkable clarity. Unlike the voluntary nervous system, which enables conscious movement, the autonomic nervous system functions continuously without conscious instruction. It regulates heart rate, blood pressure, respiration, digestion, pupil size, body temperature, glandular secretion and countless other physiological functions. Within moments, it adjusts cardiovascular activity during exercise, redistributes blood flow according to metabolic demand, regulates perspiration and coordinates digestion after meals. Every moment of life depends upon this silent regulatory system, yet most people remain entirely unaware of its existence.

Even this extraordinary system represents only one layer of biological regulation. The endocrine system simultaneously coordinates metabolism, growth, reproduction, immunity, stress responses and tissue repair through hormones secreted by glands throughout the body. Hormones such as insulin, glucagon, cortisol, thyroid hormones and growth hormone act at concentrations measured in parts per trillion, yet exert profound physiological effects through intricate feedback loops that continually adjust according to the body's changing needs. The conscious mind neither initiates nor supervises these processes.

At the cellular level, the complexity becomes even more astonishing. The human body contains approximately 37 trillion cells, each functioning as an extraordinarily sophisticated living system. Every cell continually exchanges information with neighbouring cells and distant organs through thousands of molecular signalling pathways. Receptors detect hormones, neurotransmitters, growth factors and cytokines, activating intracellular communication networks that regulate gene expression, metabolism, cell division, repair and specialized functions. Every second, innumerable molecular interactions occur within every cell, allowing the body to respond continuously to both internal and external conditions.

Modern molecular biology has further revealed that the human genome is not a static repository of information but a dynamically regulated system. Although nearly every cell contains the same DNA, different genes are activated or suppressed according to the needs of each tissue. This allows liver cells, neurons, heart muscle cells and immune cells to perform vastly different functions despite possessing nearly identical genetic material. Thousands of genes are continually switched on and off in response to developmental signals, nutrients, circadian rhythms, hormones and environmental influences. These processes occur without conscious awareness, yet govern growth, repair, adaptation, and survival throughout life.

Equally remarkable are the mechanisms preserving the integrity of the genome. Every day, each human cell experiences thousands of spontaneous DNA lesions arising from metabolism, oxidative stress and environmental influences. Highly sophisticated DNA repair systems continuously identify and correct this damage with extraordinary accuracy, preserving genomic stability across trillions of cells without conscious participation.

Proteins, the molecular machinery responsible for virtually every biological process, likewise require continuous maintenance. Newly synthesized proteins must fold into precise three-dimensional structures before becoming functional. Molecular chaperones assist this process, while damaged proteins are removed through elaborate quality-control systems such as the ubiquitin-proteasome pathway and autophagy. Without these mechanisms, defective proteins would accumulate, impair cellular function and contribute to disease.

Perhaps no organ better illustrates biological complexity than the human brain. Although it represents only about two percent of body weight, it consumes approximately twenty percent of the body's resting energy. Its approximately eighty-six billion neurons communicate through hundreds of trillions of synapses, supporting perception, memory, language, reasoning, emotion and movement. Yet the neural circuits responsible for respiration, cardiovascular regulation, body temperature, sleep and countless reflexes function automatically throughout life. Modern neuroscience increasingly shows that many neural processes underlying perception and decision-making begin before conscious awareness arises, reinforcing that conscious thought represents only a small fraction of the brain's total activity.

Sleep provides perhaps the clearest demonstration of human dependence upon unconscious physiological regulation. During sleep, the brain remains highly active, consolidating memories, recalibrating neural circuits, removing metabolic waste through the glymphatic system, promoting tissue repair, strengthening immunity, regulating metabolism and synchronizing endocrine rhythms. Meanwhile, the cardiovascular system, kidneys, liver, lungs and every other vital organ continue functioning without interruption or conscious supervision.

Recent advances in systems biology have further transformed our understanding by revealing that health emerges from continuous communication among genes, proteins, cells, tissues, organs, hormones, the nervous system, the immune system and even the intestinal microbiome. Every physiological system interacts with numerous others through vast interconnected feedback networks.

This integrated view reveals that the body is not governed by a single controlling centre but by innumerable interacting regulatory systems. Every heartbeat, every breath and every movement depends upon extraordinary biological coordination extending across multiple physiological systems. The deeper science investigates living organisms, the more evident this complexity and interdependence become.

It is precisely here that the insight of Sri Jagannatha Dasaru acquires extraordinary significance. The Bhojana Rasa Vibhaga Sandhi does not seek to explain the molecular mechanisms of physiology, its purpose is far deeper. It invites the devotee to contemplate that the countless processes sustaining life are not governed by personal effort or independent human power. The astonishing order revealed by modern science becomes an invitation to humility. Every heartbeat, every breath, every cellular repair, every neural impulse and every moment of existence remind us that life is sustained through processes operating entirely beyond our conscious control.

Science describes these mechanisms with increasing precision, revealing how they function according to the laws governing living systems. Sri Jagannatha Dasaru directs our attention beyond the mechanisms to their ultimate sustainer. From the perspective of the Bhojana Rasa Vibhaga Sandhi, the harmonious coordination observed throughout biology is not merely the consequence of impersonal physical laws but the continuous expression of Sri Hari's sovereign governance. Thus, every scientific discovery that uncovers greater biological complexity also deepens the devotee's appreciation of the Sandhi's timeless teaching, the individual is never truly independent. Every moment of life, from the first breath to the last heartbeat, rests entirely upon the uninterrupted grace, wisdom and sustaining power of the Supreme Lord.

In the next Mantralaya series, we will build directly upon this foundation by examining digestion, metabolism, the gut microbiome, cellular bioenergetics and the profound teaching of Bhagavad Gita 15.14, showing how Sri Jagannatha Dasaru presents Vaishvanara (Vishwanara Devaru) as the true digester of food and the Lord presiding over the body's perpetual inner Yajna.

The devotion towards Sri Raghavendrateertharu is the ultimate truth and is the most simple and effective way to reach Sri Hari  - "NAMBI KETTAVARILLAVO EE GURUGALA"! “Those who have complete faith in this Guru will never be disappointed.”
