Dr. Azad’s clinic. Late afternoon. The boys have just arrived, still holding the book they found in the library. The clinic is quiet, case-sheets stacked neatly on the desk. Dr. Azad closes a patient file and turns to them.
Dr. Azad: So, what did Charaka teach you this time?
Kabir: This chapter was dramatic. Three people almost died, and in each case, what brought them back was breath, just breath.
Rohan: It felt like a lesson on first aid and cardiopulmonary resuscitation. The boy choked by smoke, the one rescued from drowning, and even the strangled thief: they were all motionless. Then Charaka restores breath, and everything else follows.
Aarav: And he says that when breath returns, the heart beats again, the senses awaken, and even the mind and reflexes like swallowing come back. It’s almost like breath carries everything.
Dr. Azad: Yes. That is a core Ayurvedic observation: breath is the threshold of life. When breath goes, vision, speech, thought, reflexes and the senses fail. When it returns, so does everything else.
Kabir: It’s elegant in a way. You watch three near-death cases and see the same pattern. Breath goes, and mind goes. Breath returns, and life returns.
Rohan: But from the perspective of modern science, I think there’s a lot missing. Is breath everything? Is Charaka assuming that disturbance of breath is the ultimate cause of death? When someone is shot through the heart, their breathing stops—so disturbance of circulation causes disturbance of breath. Similarly, injury to the brain can disrupt circulation, respiration, movement, cognition, and more. Surely Charaka recognized that death could result from multiple interacting causes.
Dr. Azad: Certainly. Even today, cardiorespiratory failure is commonly recorded as the immediate cause of death, although the underlying causes may vary widely. In Charaka’s system, the heart was regarded as the seat of channels that carry Prāṇa. So, the connection between the heart, breath, and life was recognized, even if not understood in anatomical terms. The two systems, respiratory and circulatory, were seen as functionally interconnected.
Rohan: That is interesting. He says Prāṇa functions from the head. He must have also observed that severe head injuries could lead to cessation of breath and, eventually, death.
Kabir: Yes! I wonder, did he know the precise anatomy and physiology of circulation and respiration?
Dr. Azad: Their anatomical and physiological knowledge was limited and observational rather than experimental. He lacked the tools needed to identify entities like oxygen or hemoglobin. His contemporaries in the ancient Greece and Rome too had many wrong notions about these systems.
Kabir: Like what?
Dr. Azad: In those times, many believed that air from the lungs entered the heart, which then pumped it through the arteries. This led to the notion that arteries carried air, not blood. Blood itself was thought to be produced from digested food, gradually transformed into bodily tissues. It was believed to be consumed during nourishment rather than continuously recirculated. The concept of pulmonary circulation, blood moving from the heart to the lungs and back, was entirely unknown then.
Kabir: What did Charaka and Sushruta think on these topics?
Dr. Azad: Suśruta understood that, after digestion, nutrients were absorbed from the gut and reached the heart. Charaka described the heart as the central source from which nourishing fluids were distributed throughout the body. This reflects an early idea of systemic distribution, though it does not correspond to the concept of circulation as we know it today.
Kabir: Is there any reference in Ayurveda textbooks that hints at blood circulation?
Dr. Azad: There is a passage in the Charaka Saṃhitā that vaguely suggests the idea of circulation, comparing the nourishment of bodily tissues to the turning of a wheel—a continuous, cyclic motion. The Bhela Saṃhitā also contains an implicit description in which the nutrient fluid is said to exit the heart, nourish the body, and then return to the heart. However, it remains unclear whether this refers to the same fluid making a complete circuit or to a fresh supply originating from the gastrointestinal tract. While these observations gesture toward some basic circulatory dynamics, the anatomical and physiological mechanisms are not explicitly defined.
Aarav: In school, we were taught that Prāṇa Vāyu means oxygen. But in this story, it’s clearly something more.
Dr. Azad: That’s a common oversimplification. Oxygen is part of what modern medicine links with respiration, but Prāṇa Vāyu in Ayurveda is a functional category: an organizing idea for all inward and life-sustaining movements, including breath, swallowing, and mental clarity. It’s not a gas, but a metaphor for a pattern of vitality.
Aarav: The text describes chest pressing and rubbing the limbs. Was that a kind of early resuscitation? Did Charaka actually use these methods?
Dr. Azad: In a limited sense, yes. Classical Ayurvedic texts do mention practices like rubbing the body, fanning, and stimulating the senses to revive the unconscious. However, the rhythmic chest pressing described in this narrative is an interpretive addition—it enhances the dramatic effect but does not come from the Charaka Saṃhitā itself. The text does not prescribe Cardio-Pulmonary Resuscitation as we understand it today. That element is a narrative device, meant to show the restoration of breath in visual terms.
Kabir: Then is the lesson still useful?
Dr. Azad: It is useful because it illustrates the functions of Prāṇa Vāyu based on clinical observation rather than abstract speculation. It captures the principle that breath governs vital functions. But as a guide to emergency care, it is incomplete. Emergency medicine requires knowledge of anatomy, physiology, and diagnostic reasoning. We must distinguish between types of respiratory failure—whether obstructive, neurological, or traumatic—because each demands a different intervention.
Rohan: And Charaka ends by mentioning Prāṇāyāma. But doesn’t explain it.
Dr. Azad: Right. That’s because in the classical medical texts it has not been mentioned. The detailed practices come from Yoga literature, not Charaka. Here, Prāṇāyāma is offered as a suggestion: if disordered breath leads to collapse, perhaps regulated breath can bring clarity.
Aarav: Still, the connection is interesting. Breath affects not just lungs, but also mind, speech, awareness.
Dr. Azad: Exactly. In Ayurveda, the functions of breath were understood through close observation of life processes and illness and not through abstract speculation. That empirical approach is where its strength lies.
Kabir: So the teaching is symbolic but still has practical value.
Dr. Azad: Precisely. Charaka offers a powerful metaphor, but not a complete map. You must respect both sides. Life begins with breath. Medicine begins with understanding what breath means: both in biological terms and in lived, human experience.
The clinic falls quiet. For a moment, they listen to their own breathing, more aware of it than before.
