The Forgotten 5,000-Year-Old Science of the Human Body w/ Dr. Vasant Lad (Transcript)

Editor’s Note: In this episode of the Know Thyself podcast, host André Duqum sits down with Dr. Vasant Lad, the founder of the Ayurvedic Institute and a pioneer in bringing Ayurveda to the Western world. Dr. Lad delves into the 5,000-year-old science of life, explaining how the five elements, the three doshas, and the nature of consciousness shape our individual health and well-being. Throughout the conversation, they explore how to cultivate balance, heal the mind-body connection, and embrace a life of awareness and longevity. (May 26, 2026) 

Introduction to Ayurveda and Dr. Vasant Lad

ANDRÉ DUQUM: Hey everyone, welcome back to the Know Thyself Podcast. We are at Soham in Asheville, North Carolina. A bit of a deviation from the normal studio shootings, and it feels great to be in nature with our guest today, who is the founder of the Ayurvedic Institute, the man who really has pioneered and brought Ayurveda to the West, which is a beautiful over 5,000-year-old lineage. And he’s trained thousands of practitioners, authored several books, and he’s the man to dive deep into all things Ayurveda with. Dr. Vasant Lad, thank you for being here.

DR. VASANT LAD: Thank you.

ANDRÉ DUQUM: Quite the pad. I want to set a bit of the context and the stage for our audience, for everybody who’s listening in who may or may not have known about Ayurveda or don’t know it at much depth. What does Ayurveda actually mean? What does that word mean?

What Is Ayurveda? The Science of Life

DR. VASANT LAD: Oh, very beautiful question. The very word, ayu veda — ayu is the life, and Veda is the knowledge, and that systematized knowledge became science. So Ayurveda is a science of life, in a simpler word. And it is so unified, it is so totally one with the universal law.

So according to Ayurveda, this spiritual energy is pure awareness. And awareness is expressing itself as the etheric space, air, fire, water, earth. These are called 5 great elements. And they are present in every tree, every flower, every human being. There is a Sanskrit quotation that, Sarvani dravyani pancha bhootikani — all organic and inorganic matter is made up of 5 great elements.

These are very important. So in the body there are smaller and bigger spaces — abdominal space, thoracic space, cranial space. So that is etheric space. At cellular level, every cell has a space, and through the cellular space there is a communication going on. If I want to communicate with you, first I have to create space in my heart and then listen. Then I have direct communication. So space is very important. Space is freedom, space is love, and space is communication.

Then the second important principle is air. Air is a principle of movement. In our body, the lungs are breathing, diaphragm is moving, heart is beating. All these movements — afferent, efferent, sensory, motor — all these movements are governed by air element. Air is the principle of movement.

Then where there is a movement, there is a friction. Where there is a friction, there is a heat — the fire. And the fire in the body is digestive fire. Liver generates large amount of heat, so liver is also seat of fire. That is called bhūtāvani. Agni is the fire, and this fire, Agni, maintains hunger, appetite, digestion, absorption, assimilation, and transformation of food into consciousness. All these are governed by fire.

Then comes water. Water is the plasma, the serum, the cytoplasm. All that biological substance — plasma, the serum — is water. And without water, cell cannot survive. Water is a universal chemical solvent.

Then comes earth. Earth is solid ground like calcium, magnesium, zinc, iron, copper. So all these 5 elements are present in our body. So this is a structural aspect of the body.

But biological combination of ether, air, fire, water, earth split into 3 doshas. Ether and air create vata. Vata is a principle of movement. Fire and water become pitta. Pitta is the biochemical activities. And kapha is earth and water — the building block material. So all these vata, pitta, kapha, they are present in every RNA, DNA as our genetic code, as our blueprint. And we carry that blueprint in our body.

So these three doshas, they were governing this biological structure of the body and psychosomatic expression of the body. These are called 3 doshas, and every individual has a unique expression of consciousness. In the true sense of the word, individual is indivisible, undivided, total unique expression of awareness. So we all are individual.

Now, based on our individual prakruti, which is your constitution, and because of change in the season, change in the time, change in the age, change in the environment, our prakruti ratio — vata, pitta, kapha — undergoes change. And that change, altered status of vata, pitta, kapha, is called vikruti. Vikruti is present altered status. And prakruti is your genetic code. And Ayurveda is a science of prakruti-vikruti paradigm.

Prakruti and Vikruti: Constitution and Imbalance

ANDRÉ DUQUM: So if I have it right, the way that you just described it, the prakruti is what you come into genetically. That’s what you’re set with. You have a constitution of these different elements in different levels. Correct. Vata, pitta, kapha. And we’re all born with a set amount of each. And then we have vikruti, which is the variation, the difference, the delta between that — as we live and eat and move in society, it changes.

DR. VASANT LAD: Correct. But this vikruti is the potential womb in which disorder may happen. If we don’t balance vikruti back to the prakruti, then there is ill health. So vikruti is the root cause of all disease, psychosomatic disorder.

ANDRÉ DUQUM: It’s a very different conception from the Western allopathic model, which I want to get into with you. But so if that is the source of disease, the vikruti, then what is the premise of what Ayurveda is trying to understand and bring to everyone’s understanding?
